A Picture Is a Claim: Computational Fluid Dynamics, Turbulence and Verification
Offshore safety engineer Saoirse Delacroix has two CFD studies of the same gas leak on a new compression module, and they disagree about where the cloud goes and which detectors see it. Independent specialist Tobiah Mensah tells her a colour picture is not an answer but a claim. In episode one hundred and twenty six we learn how to weigh that claim. We build the finite volume method from a mass balance, estimate dye through a doorway with central differences and upwinding, and see numerical diffusion smear a plume. Patankar and Spalding's SIMPLE algorithm negotiates pressure and velocity over…
