曲面上的界面热传递还没有得到充分的理解。本研究报告了一个显着减少在凸形流体-固体界面的传热。曲率对Kapitza长度和热适应系数的影响进行了研究,为气相和液相,以了解大的温度跳跃的发生。研究还从理论上考察了非平衡效应从凸面进入气体的深度,揭示了凸面处努森层的膨胀。
Interfacial heat transfer across curved surfaces has not been understood sufficiently well. The present study reports a significant decrease in heat transfer at a convex fluid-solid interface. Effects of curvature on the Kapitza length and the thermal accommodation coefficient are investigated for both gas and liquid phases to understand the occurrence of large temperature jumps. The study also examines the penetration depth of non-equilibrium effects into gas from the convex surface theoretically and reveals the expansion of the Knudsen layer at convex surfaces.
