COMSOL 6.2 - Pressure (Adiabatic)

Pressure (Adiabatic)

Use the node to specify a prescribed pressure pbnd, that acts as a pressure source at the boundary, typically an inlet or outlet. In the frequency domain, pbnd is the amplitude of a harmonic pressure source. The adiabatic condition states that no heat flows into or out of the boundary:

This condition is in general not physically correct on a solid wall because solids are generally better thermal conductors than air.

Pressure

Enter the value of the pbnd (SI unit: Pa) at the boundary. The default is 0 Pa.
