Abstract: The flow around a circular cylinder with porous material coating (PMC) is numerically investigated based on unsteady Reynoldsaveraged Navier–Stokes (URANS) method at subcritical Reynolds number. The results are compared ...

Abstract: This paper takes a low-speed axial contra-rotating compressor as the experimental object, and the sensor array is used to collect the pressure sequences in stall conditions for different speed configurations. These pressure ...
