摘要The heat transfer of a Graetz problem to a double-pass parallel-plate heat exchanger under uniform wall temperatures to enhance the device performance improvement is investigated theoretically. The theoretical mathematical model is solved analytically using the separation of variables, superposition principle and an orthogonal expansion technique in extended power series. The theoretical results show that the power-law fluids results in the significant heat-transfer efficiency improvement as compared with those in an open conduit (without an impermeable resistless sheet inserted), especially when the double-pass device was operated in large Graetz number. The results show that the good agreement between the experimental results and theoretical prediction. The effects of impermeable-sheet position and power consumption increment for power-law fluids have also been presented.
