Abstract: The heat flux in the focal region of a compound parabolic collector (CPC) and the receiver's surface is varying and ununiform, and its effective absorption is one of the challenging tasks. It opens new opportunities for suitable and appropriate designs for the receiver. Thus, a new design of the mini-channel receiver is proposed based on fluid flow optimization to address the issue. The pressure drop analysis enables the decision of the dimensions of the proposed mini-channel receiver. MATLAB programming enables flow optimization through a mini-channel receiver under variable solar flux falling its surface to attain the highest possible temperature. The performances of the optimized and parallel fluid flow mini-channel receivers are compared by integrating them with CPC.
