So gone and lost not even God can find me

Posted May 19, 2023 at 15:14 by andrenel

I started a CFD project and lost my way. I keep going around like the Blair Witch Project. Nothing I have tried has worked.

I did some simple simulations and got good results -- numbers agree with empirical results.

So I decided to try to apply CFD to an inline gas filter. The filter consists of a housing and a pleated fabric filter. The fabric has around 50 pleats with a porosity of 0.4. I simulated the porosity by cutting slots in the CAD model pleats equally...

Turbulence is a complex phenomenon that occurs in most engineering applications involving fluid dynamics. It is characterized by the irregular and chaotic motion of fluid particles, which can cause significant fluctuations in velocity and pressure. Until now, there has not been a single and practical turbulence model that can reliably predict all turbulent flows with sufficient accuracy. whereas many turbulence models have been developed from the perspective of finding different compromises between...
