摘要:
针对一款适用于大功率车用柴油机的筒式温差发电装置提出优化方案, 该方案基于对热端集热器、温差发电模块及柴油机的仿真模拟的综合评价, 包括Fluent对于温差发电器冷热端温度场、内部流场和背压的仿真, Matlab对于温差发电器发电计算, 以及GT-Power对于背压引起的柴油机功率损失计算.针对原结构中存在换热效果不理想的问题, 提出加装不同尺寸导流装置来强化换热, 可使整体性能大幅提升.本研究中, 当采用60 mm导流装置时, 系统净输出功率取得最大, 达到651.1 W, 较原系统436.5 W提高了49.2% .
Abstract:
The simulation and optimization scheme of cylindrical thermoelectric generating system for exhaust waste heat recovery of a large power vehicle diesel engine was proposed. This scheme was based on the simulation of thermoelectric generator,hot-side collector and diesel engine. It consisted of the hot-cold side temperature field,inner flow field and exhaust back pressure of thermoelectric generating system calculated by the Fluent software,thermoelectric generator’s electric energy production calculated by Matlab,and the power loss caused by exhaust back pressure of diesel engine calculated by GT-Power. To solve the problem of low heat transfer efficiency in the original system,different sizes of guiding device were installed,which greatly enhanced the performance. It was found that the 60 mm guiding device has the largest net output power of 651.1 W,which increases by 49.2% compared to 436.5 W in the original system.
