kpperturbations
kpperturbations refers to a specific type of numerical artifact that can arise in the computation of turbulent flows, particularly when using certain numerical methods. These perturbations are not representative of physical turbulence but rather are introduced by the discretization scheme and the solver's interaction with the flow equations. They often manifest as spurious oscillations or unphysical gradients in the computed flow field.
The origin of kpperturbations can be traced to the way fluid dynamics equations are approximated on a
Identifying and mitigating kpperturbations is a critical aspect of performing reliable computational fluid dynamics (CFD) simulations
