The optimal fan angle (lateral reduction angle of the pin–fin) and fan radius ratio (ratio of the radius of the front section of the pin–fin to that of the rear part) were found in this work while other parameters remained constant. Six design points for fan angle and eight design points for fan radius ratio were used to estimate the heat transfer performance, friction factor, and area-averaged Nusselt number. According to the results, altering the fan angle and fan radius ratio can raise the Nusselt number by up to 8.4 and 6.1, respectively, over the circular pin-fins example at Re = 25,000. At Re = 25,000, the channel with pin-fins in the shape of fans has a maximum heat transfer performance that is greater than the reference cases by 1.97 with a change in fan angle and 3.8 with a change in fan radius ratio. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
