| 1 | Study on the Control Strategy of Free Piston Expander-Linear Generator Used for Organic Rankine Cycle Waste Heat Recovery显示文摘This study presents a free piston expander-linear generator (FPE-LG) for engine waste heat recovery.The control strategies based on displacement (control strategy A) and valve timings (control strategy B) are proposed.The operation and output characteristics with different control strategies are conducted.The results show that control strategy has significant effect on the FPE-LG performance.When FPE-LG operates with control strategy A,the operation frequency is determined by the intake pressure,advanced exhaust duration,fixed position point and external load resistance,whereas it is only related with the intake/exhaust time and advanced exhaust duration (ta) for control strategy B.The external load resistance has slight influence on the stroke length for these two control strategies.For control strategy A,when advanced exhaust duration is more than 40 ms,the stroke length rises with the intake pressure,whereas it first rises and then reduces when advanced exhaust duration is less than 40 ms.There exist the optimal external load resistance and advanced exhaust duration to achieve the maximum power output with control strategy A,whereas the average power output reduces with the increasing advanced exhaust duration when using control strategy B.Stable operation and high power output can be obtained by using different control strategies and adjusting relevant operation parameters. | HOU Xiaochen ZHANG Hongguang ZHAO Tenglong SHI Xin XU Yonghong LI Jian GE Zhong ZHANG Jun WU Yuting | 2021 | Journal of Thermal Science2021，30，2： | 1 |
| 2 | Study on the Performance of Organic Rankine Cycle-Heat Pump(ORC-HP) Combined System Powered by Diesel Engine Exhaust显示文摘This study presents an ORC-HP combined system driven by diesel engine exhaust. This paper focuses on the feasibility and performance of the combined system under heating mode to heat a coach. The performances of the combined system with different parameters, including condensation temperature and evaporation pressure in ORC system, gas cooler outlet pressure, gas cooler outlet temperature and evaporation temperature in HP system, have been analyzed. The results show that the combined system can fully meet the demand of heat production. The optimal flow division ratio(rp) of 0.32 is selected by analyzing the system performance. Low condensation temperature is beneficial to the combined system performance. There exists a suitable range of evaporation temperature, gas cooler outlet pressure and gas cooler outlet temperature to achieve excellent performance. The heating coefficient of performance(COP_h) shows a first increasing and then decreasing trend with gas cooler outlet pressure, namely there exists an optimal gas cooler outlet pressure that achieves the maximum COP_h. The maximum total efficiency, COP_h and heating capacity can reach up to 48.44%, 4.78 and 176.56 kW, respectively. These results show significant energy savings by applying the ORC-HP combined system. | ZHAO Tenglong YU Fei ZHANG Hongguang WU Yuting WANG Yan | 2019 | Journal of Thermal Science2019，28，5： | 0 |
| 3 | Injectable Fiber Electronics for Tumor Treatment显示文摘Electrochemical therapy emerged as a low-cost and efective method for tumor ablation.However,it has challenges such as the production of toxic byproducts and the use of rigid electrodes that damage soft tissues.Here,we report a new injectable and tissue-compatible fber therapeutic electronics for safe and efcient tumor treatment.The design of aligned carbon nanotube(CNT)fber as electrodes endowed the device with high softness and enabled mini-invasive implantation through injection.Under a mild voltage(1.2 V),the fber device released hydroxyl ions to alter the local chemical environment of the tissues without additional toxic products/gases,leading to immediate death of tumor cells.The fexible fber device could form stable interface with tissues and showed good biocompatibility after implantation for 30 days.The in vitro experimental results showed the fber device could efciently kill 90.9%of QGY-7703 cancer cells after a single treatment in a few minutes.The tumor-bearing animal models proved that the fber therapeutic device could efectively inhibit the growth of tumor tissues,indicating it is a safe,efective,controllable and low-cost method for tumor therapy. | Yang Zhao Chuanrui Chen Yangyang Qiu Tenglong Mei Lei Ye Huan Feng Ye Zhang Liyuan Wang Yue Guo Xuemei Sun Jiaxue Wu Huisheng Peng | 2022 | Advanced Fiber Materials2022，4，2： | 0 |
