Taylor green vortex initial condition
Webfind that flows that begin from Taylor–Green (referred to as TG below) and Kida– Pelz (referred to as KP below) initial conditions are good candidates for the study of vortex surfaces, because their initial topology is relatively simple and both of these periodic flows have many symmetries to facilitate construction of initial vortex ... WebDec 1, 2024 · Presented results for decaying Taylor–Green vortex flow serve as the validation case for the code. With the specific initial condition and additional post-processing routines, the code is capable of simulating a decaying homogeneous isotropic turbulence (DHIT).
