Abstract
A newly developed type PCHE(Printed Circuit Heat Exchanger), which has a longitudinal corrugation flow channel, was fabricated using etching and diffusion bonding to evaluate its hydraulic performance. The pressure drop characteristics obtained from the experimental results are presented and the local friction factors associated with different hydraulic diameters and inclination angles are discussed. The results of a three-dimensional numerical simulation are presented, conducted using commercial CFD(Computational Fluid Dynamics) software at lower Reynolds number range. The numerical results were validated by experimental data obtained from helium gas experimental apparatus. The results of CFD prediction show fairly good agreement with the experimental data.
