聚变堆包层第一壁流道换热性能研究
Study on heat transfer performance of flow channels in first-wall of fusion reactor blanket
摘要
Abstract
A set of apparatus of the U‐shape flow channels with air as coolant was designed to study the flow channels in the first‐wall of fusion reactor blanket .The temperature distributions of the flow channels in the first‐wall were measured along the flowing direction ,and the impacts of flow channel diameter ,Reynolds number ,temperature ,inlet velocity and corner shape on heat transfer perform‐ance of the first wall were investigated by comparing the measured data with numerical simulation re‐sults .The experiment results show that the largest U‐shape flow channel with 30 mm × 30 mm square cross‐section could increase performance of heat transfer between coolant and flow channel wall by 23% without the increasing coolant flow resistance ,the modified flow channel design with the conver‐ging flow area could further enhance the heat transfer by almost 15% ,with which the numerical simu‐lation results agree well .Research results show that the heat transfer performance of flow channels could be efficiently increased by modifying the size and shape .关键词
