The flow behavior and heat transfer feature in a two-dimensional channel with flexible wings are numerically investigated in present work. Furthermore, the influences of Young's modulus of wings and Reynolds number on the fluid flow behavior and heat transfer performance are probed. In addition, the dynamic behavior of flexible wings is explored as well. The results indicate that three motion modes of flexible wings occur, which are deflection mode, vibration mode and flapping mode. The numerical results indicate that the larger the Young's modulus, the larger Reynolds number is required for the emergence of the motion mode transition. The overall performance coefficient (PEC) is used to measure the comprehensive performance of flexible wings. It is found that PEC peaks occur near the rear flexible wing when the motion mode transition appears. In specific case, PEC increases by up to 1.145 under the combination effects of front flexible wing blocking and rear flexible wing flapping.
