What is the effect of mesh size on degassing BC?

Hi I am simulating a kind of electrolyzer in Fluent. Consider a 2D-box, the bottom boundary is opening, top boundary is degassing, gas is generated from a part of left side boundary and right...

Under which circumstances is it fundamentally true to simulate a two-component physical system by using a single-component (LBM) model?

I am using a single-component - two phase pseudo-potential LB model and need to compare my results. I, tried to compare my results with experimental data of falling of a water droplet into air...

Does the RK equation of states predict a higher density ratio or CS in a specific reduced temperature?

For a two-phase flow and in a specific reduced temperature (e.g. Tr=0.75), does the Redlich–Kwong (RK) equation of states predict a higher density ratio or Carnahan-Starling (CS)? Could you...

What causes these density and temperature profiles within a static bubble?

consider a static vapor bubble within a 2D domain surrounded by fluid. at the beginning, the temperature is the same in all nodes. In order to see the changes in density and temperature of the...

Does the temperature of a static droplet remain constant during evaporation?

I am simulating the evaporation of a static droplet using the lattice boltzmann method. The ambiguity for me is that, the temperature of the drop remains constant during the evaporation and after...
