How can one simulate bubble hydrodynamic with based CFD software into electroflotation column?

More Issam Ksentini's questions See All

I look for simulating the formation of bubbles by electroflotation column, how to do this with cosmol or fluent ?

In fact, i did not find researches or tutorials introducing the simulation of bubble generation by insoluble electrodes :/

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

What is the characteristic length to determine the Reynolds number for the scattered turbulent fluid flow?

Dear all, I just saw this example in FB on the difference between laminar flow and turbulent flow. The flow from a pipe hits the sink and scattered. The flow from the pipe is characterized as...

It is not clear what exactly you want to simulate. Is it bubble growth in electrode and subsequent detachment or bubble shape deformation while it is rising? Anyway, coupled level set VOF (CLSVOF) method of FLUENT is good to simulate any bubble hydrodynamics.

We are looking for both detachment of bubbles AND its hydrodynamic characteristics of produced bubbles such as size and rise velocity

If you know your bubble size at time t=0, then it is easy to simulate the detachment and subsequent rise process using FLUENT. However, if you would like to simulate bubble growth on the electrode, it is not straightforward. Bubble growth rate kinetics must be separately coupled through a user defined function to FLUENT.
