摘      要：To deal with the aerodynamic heating on the aircraft surface,a potential solution is to utilize liquid cooling via the channels in part of the *** is a typical problem of flow and heat transfer in channels with unilaterally-heated *** enhancement of heat transfer in the channel is significant due to the high heating *** optimal velocity and temperature fields are obtained first based on the field synergy optimization *** rib configurations are proposed to produce the longitudinal vortices suggested by the optimal velocity *** flow and heat transfer characteristics of different rib configurations are obtained by numerical *** numerical simulations show that the heat transfer enhancement of the rib configurations are quite different,but the pressure drop increases similarly in the laminar flow range of Re = 500–*** mechanism of heat transfer enhancement with the single/double-inclined ribs for the unilaterally-heated channel is *** best enhancement of geometric parameter among the investigated parameters such as the angle,length,radius and the spacing of the ribs is obtained.
