DSMC results of low-Mach flow over circular cylinder
I am currently studying the flow over blunt bodies in the slip-flow and transitional regime (Knudsen number >0).
For benchmark purposes in the rarefied regime, DSMC (direct simulation monte carlo) is the numerical approach of choice.
I found a ton of papers with DSMC calculations for the super- and hypersonic flow over circular cylinders, but not a single calculation for low-Mach flows.
I know, the computational cost of a DSMC scales with Ma^-2, so it is natural that there are more results for Ma>>1.
But in the last few years, variance reduction Methods for DSMC were developed (like IPDSMC or LVDSMC) that remove the Ma^-2 dependency.
Unfortunately, the authors of these methods only tested their codes for channel flows (Couette and Poiseuille). So here is the question:
Does anyone have DSMC-like results for the low-Mach flow over circular cylinders or knows where they are to be found?
Many thanks in advance.
It would already help if someone knew that there are no such computations available so far.
Why is nobody replying to my threads :(
