2024年6月1日 · In this work, a computational fluid dynamics-population balance model (CFD-PBM) coupled method is employed to systematically investigate the effects of operating conditions and structural parameters of KSM on droplet size and its distribution, to further reveal the liquid–liquid dispersion characteristics.

Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid ( liquids and gases ) with surfaces ...

CFD is used wherever there is a need to predict fluid flow and heat transfer, or to understand the effects of fluid flow on a product or system. CFD analyzes different properties of fluid flow, such as temperature, pressure, velocity, and density, and can be applied to a broad range of engineering problems across industries, including:

2024年9月25日 · CFD-PBM numerical simulation is a powerful tool in the research of droplet swarm behavior. In this work, an artificial neural network (ANN) based droplet breakage frequency function is established ba...

Compressible liquid: 对于高压下的液体介质，可以选用compressible liguid 定义密度。 自然对流主要是由于空气的密度差异而导致的流动，这个密度差异主要来自温度变化。

2021年1月22日 · The approach coupling computational fluid dynamics and a population balance model (PBM) was adopted to simulate the hydraulic performance of liquid–liquid dispersions in a pump-mixer. Behaviors of the drop breakage and coalescence were considered in the PBM.

2020年4月23日 · 在CFD计算中，液体常被当作不可压缩流体处理。然而在高压作用下，液体的可压缩性不可忽略，此时可以使用Fluent提供的Compressible liquid密度方法。本文描述该方法的一些基本理论。

2021年12月1日 · Numerical simulations of silicone oil–water two-phase turbulent dispersion mixing in Q-type static mixers (QSM) are performed using computational fluid dynamics (CFD) coupled with a population balance model in the range of Re = 8000–24 000.

2020年3月1日 · The CFD allows for a more detailed analysis of the emulsification process: the baffles, installed at the mixer's walls, generate large-scale longitudinal vortices enhancing mixing in the transversal plane; most of the breakup occurs near the wall, while the vortices ensure transport of the disperse phase to and out of the wall.
