我们报道了一个由自然对流边界层下游的流动共振驱动的对流换热增强，该边界层受到中等撞击射流的扰动。我们的实验观测和大涡模拟证实了热边界层之间的流动共振和射流撞击区域的周期性流动。从自然对流基线开始，下游换热增强超过40%。研究结果支持了高效强化传热方法的发展。
We report a convective heat transfer enhancement driven by flow resonance downstream of a natural convection boundary layer that is perturbed by a moderate impinging jet. Our experimental observations and large eddy simulations confirm flow resonance between the thermal boundary layer and a periodic flow at the jet-impinging region. Downstream heat transfer enhancement from the baseline of natural convection exceeds 40%. The results support the development of efficient heat transfer enhancement methods.
