cooling_drag(state, settings, geometry)[source]#

Computes the cooling drag based on the results of the Heat Exchanger operation

Inputs:
state.
conditions.freestream.

density [kg/m^3] velocity [Knots] pressure [Pascal]

energy.coolant_line.heat_exchanger.

pressure_differential [Pascal] mass_flow_hex [kg/s]

analyses.aerodynamics.vehicle.reference_area [m^2]

Outputs:

cooling_drag [Unitless]

Assumptions: The density across the duct is equal to the freestream density of air. Inlet area is varied based of required inflow required
