mach-uniform algorithm for LES/DNS

I'm interested in an algorithm described in the paper titled "A robust, colocated, implicit algorithm for direct numerical simulation of compressible, turbulent flows, Journal of Computational Physics 205 (2005) 205"221".

This algorithm is intended to give a uniformly accurate and efficienct results for all mach regimes and also robust for high Re number flows. So, it also seems suitable for LES and DNS.

I wrote a code following the chart/description given in the paper to use in my thesis work. But, I am not able to validate test cases in the paper. I think that there may be an algoritmic problem, rather than my programming skills.

Suggestions from anyone who familiar with these type algorithms(may be same algorithm) would be very valuable for me.

Thank you.
