Abstract

The multiple periodic boundary conditions were adopted in both the streamwise and transverse directions in a wavelength section of a cross-wave channel to model flow and heat transfer in a primary surface recuperator, as the ratio of amplitude of waviness to channel pitch is greater than 1/4. The channel wall temperature is further modified as a linearly decreasing profile. It is found that as the ratio of the amplitude to channel pitch (A/P) increases, the heat transfer is augmented, but the pressure drop also increases. When the ratio A/P is 0.333, the CW channel has the best overall performance.
