I am working on the development of an Earth-Air Heat Exchanger (EAHE) and I was wondering if the Sand-grain Roughness model could be used to simulate the thermal performance of corrugated pipe walls (of about 10 mm).
I tried to geometrically draw the corrugation but the model was very heavy when I launched the simulations.
Thank you very much in advance!

It is possible depending on what kind of corrugation you are modelling. If the corrugations are tiny (relative to the flow passage), then modelling it as a rough wall works. I would recommend you try validating your work with a similar cases before actual works.
