| 1 | Effect of source location on particle dispersion in displacement ventilation rooms显示文摘A proposed computer model for predicting aerosol particle dispersion in indoor spaces was validated with experimental data found in th literature,and is then used to study the effect of the area and point source locations on particle dispersion in displacement ventilation(DV) rooms The results show that aerosol source location has a strong impact on the spatial distribution and removal rate of indoor particles.Particle remova performance depends strongly on ventilation efficiency and particle deposition rate on indoor surfaces.Important consideration for both relativ ventilation efficiency and deposition rate consists of the position of the aerosol source relative to the main airflow pattern and the occupied zone. | Ke Zhong Yanming Kang Youjun Wang | 2008 | Particuology2008，6，5： | 7 |
| 2 | Effects of supply air temperature and inlet location on particle dispersion in displacement ventilation rooms显示文摘The effects of supply temperature and vertical location of inlet air on particle dispersion in a displacement ventilated (DV) room were numerically modeled with validation by experimental data from the literature. The results indicate that the temperature and vertical location of inlet supply air did not greatly affect the air distribution in the upper parts of a DV room, but could signiflcantly influence the airflow pattern in the lower parts of the room, thus affecting the indoor air quality with contaminant sources located at the lower level, such as particles from working activities in an offlce. The numerical results also show that the inlet location would slightly influence the relative ventilation efflciency for the same air supply volume, but particle concentration in the breathing zone would be slightly lower with a low horizontal wall slot than a rectangular diffuser. Comparison of the results for two different supply temperatures in a DV room shows that, although lower supply temperature means less incoming air volume, since the indoor flow is mainly driven by buoyancy, lower supply temperature air could more efflciently remove passive sources (such as particles released from work activities in an offlce). However, in the breathing zone it gives higher concentration as compared to higher supply air temperature. To obtain good indoor air quality, low supply air temperature should be avoided because concentration in the breathing zone has a stronger and more direct impact on human health. | Yanming Kang Youjun Wang Ke Zhong | 2011 | Particuology2011，9，6： | 5 |
| 3 | RELATIVE LEVELS OF INDOOR AND OUTDOOR PARTICLE NUMBER CONCENTRATIONS IN A RESIDENTIAL BUILDING IN XI'AN显示文摘The time series of indoor and outdoor particle number concentrations in a naturally ventilated residential building in Xi’an were tested simultaneously for 7 days in summer. The relationships between indoor and outdoor con-centrations were examined and discussed, and linear regression analysis was employed to correlate the indoor and outdoor concentrations. The diurnal cycles of indoor and outdoor particle concentrations of different particle size ranges all showed positive correlations between indoor and outdoor number concentrations. The I/O ratios of number concen-trations varied with the increase of particle size in the range of 0.89 (±0.19) to 0.99 (±0.15). | Yanming Kang Ke Zhong Shun-Cheng Lee | 2006 | China Particuology2006，4，6： | 3 |

| 5 | Analysis of the factors influencing the airflow behavior in an impinging jet ventilation room显示文摘A validated CFD model is employed to predict the airflow behavior in an impinging jet ventilation(IJV)room with cool,isothermal or warm jets.By using the numerical results,the influences of jet discharge height,supply grille shape and room height on the jet flow behavior as well as the draught discomfort are analyzed for IJV operating in heating scenarios.The results indicate that the warm supply jet of IJV rises upward to the ceiling after spreading along the floor for a certain distance due to thermal buoyancy,resulting in a limited dispersion area,while the cool and isothermal jets of IJV always spread along the whole floor.When IJV is used for space heating,the lower the jet discharge height,the farther the supply air spreads along the floor,and the supply grille shape and room height almost have no effect on the air dispersion area.The results also show that the energy-efficient advantage of IJV in its heating mode compared to the mixing ventilation(MV)system is more remarkable in higher rooms.Moreover,there is a risk of draught discomfort in IJV heating rooms and it is recommended to wear socks to avoid this discomfort. | Xiufeng Yang Xiao Ye Bin Zuo Ke Zhong Yanming Kang | 2021 | Building Simulation2021，14，3： | 2 |
| 6 | Transport of black carbon aerosols from non-local sources:A case study in Shanghai显示文摘Black carbon(BC) aerosol mass carried by winds of varying directions from non-local sources was estimated based on hourly measured data of BC mass concentration(C_(BC)) and meteorological parameters from January 2008 to December 2012 in Shanghai,and the relationship between annual average C_(BC) and wind speed was analyzed.The results show that the annual average C_(BC) decreased with wind speed for speeds exceeding 0.3 m/s.The relationship between the two was determined by a linear fit with correlation coefficient 0.88.Assuming BC aerosol mass of non-local sources transported by a southeast wind was zero,annual average BC concentrations(μg/m^3) carried by winds of variable direction were 1.99(southwest),1.95(west),1.15(northwest),0.54(south),0.39(north),0.01(northeast),and 0.01(east).BC aerosol mass of non-local sources transported by wind to Shanghai was about 6404.051 per year,among which the total contribution of southwest,west,and northwest winds was nearly 84%.The aerosol mass transported to Shanghai in winter accounted for 35%that of the entire year,and was greater than that of the other seasons. | Hongqiang Wang Yanming Kang Qianshan He Yonghang Chen | 2015 | Particuology2015，13，3： | 2 |
| 7 | Seasonal variation in particle contribution and aerosol types in Shanghai based on satellite data from MODIS and CALIOP显示文摘Although the concentration of atmospheric particulate matter in Shanghai has declined in recent years,aerosols remain one of the major pollutants affecting air quality.Herein,spatio-seasonal variation in aerosol optical properties and aerosol types were studied overa 10-year period(2006-2015)in Shanghai,China,using satellite data from Moderate Resolution Imaging Spectroradiometer(MODIS)and CloudAerosol Lidar with Orthogonal Polarization(CALIOP).The average aerosol optical depth values for central urban and suburban areas of Shanghai were between 0.9 and 1.0.Clear seasonal variation in aerosol concentrations occurred,causing strongest attenuation in summer and weakest attenuation in autumn.Polluted dust,polluted continental(urban/industrial)and smoke aerosols were the main aerosol types.Desert dust aerosols occurred in the Shanghai area at higher altitudes(greater than 3 km)in spring,related to dusty weather in the north;while in winter,smoke aerosols occurred at high altitudes,related to haze pollution in the north.The aerosols detected in autumn were mainly from local sources,comprising polluted dust,polluted continental,and smoke aerosols.Aerosols in Shanghai clearly reflect both local and regional sources at different times. | Qiong Liu Xin Liu Tongqiang Liu Yanming Kang Yonghang Chen Jiming Li Hua Zhang | 2020 | Particuology2020，18，4： | 2 |

| 10 | Aerosol transportation in horizontal channels w让h gravitational effects显示文摘Aerosol particle deposition in a narrow horizontal channel with gravitational effects is studied in the laminar flow regime. A general explic让 solution for predicting the aerosol transportation in the channel is obtained theoretically. The characteristics of the asymmetric concentratio n profiles and their dependence on gravitational settling are analyzed for different settings of the diffusion and sedimentation parameters. Aerosol deposition on the channel walls, which is influenced by a combination of mechanisms, is also analyzed. The results are compared with those from simplified models obtained in previous studies in which only diffusion or gravity was considered. The analysis reveals that the literature results regarding this aspect may be simplified with the present solution under specific conditions. | Yongwei Gao Ke Zhong Yanming Kang | 2019 | Particuology2019，17，3： | 1 |

| 13 | Theoretical investigation on submicron particle penetration through circular tubes inside a porous medium显示文摘The analytical infinite series solution of submicron particle transport in a circular tube bounded by a porous wall,such as a pinhole,is determined under the slip velocity boundary condition,and the solution is verified by using the experimental data in the previous studies for the specific cases.The results show that particle penetration rate increases with the increase of the porous parameter,the axial pressure drop,and the pinhole radius,whereas it decreases with increasing the pinhole length.The penetration rate of nano-particles are more sensitive to the variation of these parameters.However,the differences between the penetrations of particles ranging from 0.3μm to 1μm are not evident because the diffusion becomes weak gradually in this size range.In addition,a further comparison is performed between the analytical solution and the existing studies,and approximate expressions are presented for accurate calculation of particle penetration rate through pinholes appearing in porous materials including filter devices and masks. | Yanrong Yu Yongwei Gao Yanming Kang | 2022 | Particuology2022，，11： | 0 |
