The fluid flows in from the region "inlet" at (10, 0, 0) m/s and out from the region "outlet". No-slip condition is set for the walls of the flow channel, and the problem is 2-dimensional with a single mesh in the Z-direction. LES (one equation eddy viscosity model) is used for turbulence calculation.

Model geometry

The meshes are as follows.

Meshes

The fieldAverage function is used to output the time averaged pressure and flow velocity as pMean and UMean for each time. These settings are made in system/controlDict.

The calculation result is as follows.

Flow velocity (U)

Flow velocity (U)

Pressure (p)

Time-averaged flow velocity at the final time (UMean)

Time-averaged pressure at the final time (pMean)
