Performance tests were carried out for a microchannel printed circuit heat exchanger (PCHE), which was fabricated with micro photo-etching and diffusion bonding technologies. The microchannel PCHE was tested for Reynolds numbers in the range of 100-850 varying the hot-side inlet temperature between 40 °C-50 °C while keeping the cold-side temperature fixed at 20 °C. It was found that the average heat transfer rate and heat transfer performance of the countercurrrent configuration were 6.8% and 10%-15% higher, respectively, than those of the parallel flow. The average heat transfer rate, heat transfer performance and pressure drop increased with increasing Reynolds number in all experiments. Increasing inlet temperature did not affect the heat transfer performance while it slightly decreased the pressure drop in the experimental range considered. Empirical correlations have been developed for the heat transfer coefficient and pressure drop factor as functions of the Reynolds number.

“…Most of these research papers computed the heat transfer characteristics for a single passage or tube bundle of the fluid flows [2][3][4][5][6][7]. However, in this paper, we conducted computational conjugate numerical analyses of the heat transfer for a monolithic whole heat exchanger with rectangular channels [8].…”

“…In this particular study, the optimized tube shape among three different cross sections was determined after the efficiency of the corresponding recuperators was compared and simulated. Tsuzuki et al [6] studied a three dimensional thermal-hydraulic simulation of a printed circuit heat exchanger by applying the computer code, FLUENT. The optimized flow channel design was accomplished by changing the fin shape and angle to reduce the pressure drop and increase heat transfer performance.…”

This study assessed the performance of a ceramic monolith heat exchanger, estimating heat transfer and pressure drop by numerical computation and the ε-NTU method. A heat exchanger consists of rectangular ducts for exhaust gas, a ceramic core, and rectangular ducts for air and exhaust gases, as well as air in the cross-flow direction. The numerical computations were performed for the whole domain, including the exhaust gas, ceramic core, and air. In addition, the heat exchanger was examined using a conventional ε-NTU method with several Nusselt number correlations from the literature to characterize the flow in the rectangular duct. The results of these numerical computation analyses demonstrated that the effectiveness of the heat exchanger, as demonstrated using the ε-NTU method with Stephan's Nusselt number correlation, came closest to the results of computation with a relative error of 2%. The air-side pressure drops indicated by the results of numerical computation were 13-22% higher than those calculated using the head loss equation with the inclusion of a friction factor that was obtained from previous experiments examining heat transfer conditions.
