Coupled magneto-fluid and thermo-mechanical simulation with experimental validation of the evolution of the molten zone during resistance spot welding

本文提出了一种新型的全耦合电-热-磁-力-流体(ETMMHD)有限元模型,该模型通过引入经典模型中所忽略的流体动力学,显著提高了对电阻点焊过程中熔池演变及喷溅现象的预测能力,并已通过 DP600 钢的实验数据得到了验证。

Numerical Study on the Effects of Wall Wettability on Heat Transfer and Flow Characteristics during Flow Boiling in Microchannels

这项数值研究表明,虽然疏水微通道表面通过快速的气泡脱离增强了传热并降低了壁面温度,但同时也增加了压力降和流动不稳定性,而亲水表面虽然改善了流动稳定性,但由于气泡粘附而导致传热效率降低且壁面温度升高。
