CNSFVHLLCStagnationInletBC
This is the base object for applying a stagnation boundary condition to the mass, momentum, and energy equations. stagnation_temperature
and stagnation_pressure
are required parameters of any objects derived from this class. CNSFVHLLCStagnationInletBC
computes several boundary quantities from the supplied stagnation temperature and pressure. Boundary temperature is computed with the assumptions laid out here via the relation:
where is the boundary temperature, is the stagnation temperature, is the velocity and is the specific heat capacity. In CNSFVHLLCStagnationInletBC
is drawn from the cell centroid bordering the boundary, e.g. it is implicit. With computed, the static pressure at the boundary is computed using the isentropic relation:
where is the stagnation pressure and is the ratio of the specific heats, e.g. .
Armed with the boundary pressure and temperature, CNSFVHLLCStagnationInletBC
also computes the boundary values for the specific internal energy , density , and specific total enthalpy for use the flux expressions of the derived mass, momentum, and energy classes.
