文摘
- •
Direct numerical simulation of compressible channel flow at high Reynolds number is performed.
- •
A recently developed compressibility transformation is tested, which shows improved accuracy with respect to classical van Driest transformation.
- •
The highly debated dependency of compressibility on the turbulent scales is investigated.
