Is the Entropic LBM useful for simulations of highly viscous flows through microchannel?

29 May 2023 0 4K Report

Let us consider a case where we need to simulate a moving cylinder in a microchannel where the Reynolds number is order of 10^(-3). Is the Entropic LBM useful in that case?

I came across oscillations in a pressure profile for a pipeline flow along the axis of a cylinder, how do I prove that these are not numerical err?

In terms of CFD, we often analyze the stability of the error using Von-Neumann analysis, especially for FDM based problems. Should we follow the same approach for a compressible fluid flow using FVM ?
