Hi All

Research papers having numerical investigation over a certain range of Reynolds number show grid independence for the highest reynolds number. The inflation layer in this case would satisfy the yplus criteria for that Reynolds number. However, if it is done for other Reynolds with the same grid, same first layer thickness, the yplus values will not be in the recommended range. Can someone suggest me that how is this done for, say four Reynolds number, 10000-40000. Is the first layer thickness changed for every Reynolds number.

yes, as raynold's number is changed, you will need different first layer height to get similar yplus. 

suggest you to please through basic definition of raynolds no. and yplus and how they depend on velocity.
