浮力作用 meaning in English

flotational process

Next , aiming at the state of the art in engineering turbulence models , one extended explicit algebraic reynolds stress model to simulate anisotropic buoyant turbulent flows . validation was done using experimental and other numerical results of turbulent thermal mixing in t - junction flows
进一步的，针对当前考虑浮力作用紊流模型的研究现状，导出了适合模拟各向异性的浮力紊流的显式代数雷诺应力模型，并利用t型交叉管内的温度混合试验成果进行了分析验证。
The mechanism of the downburst formation was also investigated based on the cloud microphysics of the simulated storm and it was found that this downburst was primarily produced by hail loading , and enhanced by hail melting and rain evaporation . and the loading and the melting of hail played a very important role in producing the downburst . the gale at the surface was caused by the severe downburst
从云微物理学角度分析了此次局地性大风的形成原因，认为由高空冰雹粒子的拖曳产生的负浮力作用是促发强下沉气流产生的主要原因，其次是冰雹的融化和雨水蒸发冷却对下沉气流起加速作用，冰雹的拖曳和融化作用对下沉气流具有决定性的作用。
