| 1 | Particle size distribution in CPFD modeling of gas-solid flows in a CFB riser显示文摘A computational particle fluid dynamics(CPFD) numerical method to model gas-solid flows in a circulating fluidized bed(CFB) riser was used to assess the effects of particle size distribution(PSD) on solids distribution and flow.We investigated a binary PSD and a polydisperse PSD case.Our simulations were compared with measured solids concentrations and velocity profiles from experiments,as well as with a published Eulerian-Eulerian simulation.Overall flow patterns were similar for both simulation cases,as confirmed by experimental measurements.However,our fine-mesh CPFD simulations failed to predict a dense bottom region in the riser,as seen in other numerical studies.Above this bottom region,distributions of particle volume fraction and particle vertical velocity were consistent with our experiments,and the simulated average particle diameter decreased as a power function with riser height.Interactions between particles and walls also were successfully modeled,with accurate predictions for the lateral profiles of particle vertical velocity.It was easy to implement PSD into the CPFD numerical model,and it required fewer computational resources compared with other models,especially when particles with a polydisperse PSD were present in the heterogeneous flow. | Qinggong Wang Timo Niemi Juho Peltola Sirpa Kallio Hairui Yang Junfu Lu Lubin Weic | 2015 | Particuology2015,13,4: | 8 |

| 3 | 不同产地沙棘果的成分分析显示文摘通过沙棘甘油三酯和甘油磷脂中的糖、果酸(气相色谱-质谱法,TMS衍生物)、矿物质(FAAS,ETAAS)、挥发性物质(顶部空间气相色谱-质谱法)、Vc(高压液相色谱)和脂肪酸(气相色谱-质谱法,甲基酯)的分析方法,优化不同产地的沙棘果。对1997年10-11月采集的中国沙棘果(CH)和8月底采集的芬兰沙棘果(FI)和俄罗斯沙棘果(RU)的成分进行比较,得到了为今后开展更广泛的沙棘项目所需要的足够的资料。中国沙棘果汁中的Vc含量极高,平均8g/l(4.2-13.2g/l),是芬兰沙棘果汁中含量的5倍。主要矿物元素的含量比其它可食用的浆果中丰富得多,钾是沙棘果(6-14g/kg,干重)和沙棘籽(5-9g/kg,干重)中的主要矿物质之一,在一些样品中铅和镉含量的增加表明存在轻微的污染。压榨的沙棘果汁中糖的含量从1-20g/100ml有很大的变化,含量最高的是晚秋收获的中国沙棘果,最低的是8月收获的芬兰沙棘果。糖主要是葡萄糖(占总糖分的50%以上)、果糖及葡萄糖衍生物。苹果酸和奎宁酸是主要的果酸(77%-97%),含量为每100ml果汁中4.2-9.1g。果汁上部油脂的特点是形成了C2-C5n-、iso-、和ante-iso乙醇,C4-C5n-,iso,及ante-ISO酸,也呈现出挥发性油脂的籽油乙醇前体。不同的产地和采收时间对挥发物有着明显的影响,整个果中的含油量为2%-11%(鲜重)。 | Heikki Kallio Yang Baoru Raija Tahvonen Mari Hakala 许涛 卢顺光 | 2003 | 国际沙棘研究与开发2003,,1: | 7 |
| 4 | Machine Vision Based Measurement of Dynamic Contact Angles in Microchannel Flows显示文摘When characterizing flows in miniaturized channels, the determination of the dynamic contact angle is important. By measuring the dynamic contact angle, the flow properties of the flowing liquid and the effect of material properties on the flow can be characterized. A machine vision based system to measure the contact angle of front or rear menisci of a moving liquid plug is described in this article. In this research, transparent flow channels fabricated on thermoplastic polymer and sealed with an adhesive tape are used. The transparency of the channels enables image based monitoring and measurement of flow variables, including the dynamic contact angle. It is shown that the dynamic angle can be measured from a liquid flow in a channel using the image based measurement system. An image processing algorithm has been developed in a MATLAB? environment. Im- ages are taken using a CCD camera and the channels are illuminated using a custom made ring light. Two fitting methods, a circle and two parabolas, are experimented and the results are compared in the measurement of the dynamic contact angles. | Valtteri Heiskanen Kalle Marjanen Pasi Kallio | 2008 | Journal of Bionic Engineering2008,5,4: | 5 |
| 5 | CFD simulations of gas-solid flow in an industrial-scale circulating fluidized bed furnace using subgrid-scale drag models显示文摘Mesoscale flow structures such as clusters and streamers of particles are characteristic features of gas-solid flow in fluidized beds.Numerical simulations of gas-solid flows for industrial-scale fluidized beds are often performed using the Eulerian description of phases.An accurate prediction of this type of flow structure using the Eulerian modeling approach requires a sufficiently fine mesh resolution.Because of the long computational time required when using fine meshes,simulations of industrial-sized units are usually conducted using coarse meshes,which cannot resolve the mesoscale flow structures.This leads to an overestimation of the gas-solid drag force and a false prediction of the flow field.For these cases,a correction must be formulated for the gas-solid drag.We have simulated a large-scale circulating fluidized bed furnace using different gas-solid drag models and compared the model results with measurements. | Srujal Shah Kari My?h?nen Sirpa Kallio Timo Hypp?nen | 2015 | Particuology2015,13,1: | 4 |
