英文摘要	In this paper, 3-D periodic numerical model for fully developed flow in a cross wavy primary surface recuperator for a microturbine system is built. The performance of flow and heat transfer is analyzed. The fields of flow and temperature in a gas and air channel are obtained. Different working conditions are numerically simulated. Numerical results are compared with experimental data concerned. Analysis results show that the flow in the gas and air channel is anti-symmetry along the centre of channel. The flow of fluid is fluctuant. The flow velocity of gas is much higher than that of air. The thermal ratio of cross wavy primary surface recuperator can reach 95.2%. The thermal ratio decreases with the improvement of gas inlet temperature. When gas inlet temperature increases by 100 K, the thermal ratio decreases by about 1%. The thermal ratio increases with the reduction of flow rate in the channel. When flow rate reduces by 40%, the thermal ratio increases by about 4%. The research results can be used to guide checking the performance of a recuperator.
