I am wondering the meaning of △y+ and how to calculate △y+. In some papers, △y+=utau*△y/v, how can I get △y?

I want to get y+, but in the paper, there is only △y+.

Any idea is highly appreciated.

Hi,

In short, y+_wall is half of the △y+_wall. In other words, the latter incorporates the cell height while the former uses the cell-center off-wall spacing.
