Abstract Geometrical modifications in microchannel geometry intended towards mitigation of flow instabilities generally results in increased pressure drop across the microchannel heat sink. To overcome this, stepped microchannels configurations with combination of narrow bottom (aspect ratio: AR = depth/width > 1) and wider top (AR

阶梯式微通道不同配置下的流动沸腾特性

摘要 旨在减轻流动不稳定性的微通道几何形状的几何修改通常会导致穿过微通道散热器的压降增加。为了克服这个问题，阶梯式微通道配置结合了窄底部（纵横比：AR = 深度/宽度 > 1）和较宽的顶部（AR
