Heat Flux - Flat Plate
This module contains functions to estimate the heat flux of the gas over a flat plate.
- pygasflow.atd.avf.heat_flux_fp.wall_temperature(L, x, Reinf_L, Ts_Tinf, Tr, Pr, kinf, eps, sigma=5.670374419e-08, laminar=True, omega=0.65)[source]
Compute the wall temperature (the radiation adiabatic temperature) for a radiation cooled flat plate with a prescribed heat flux for a compressible flow.
- Parameters
- Lfloat
Length of the flat plate
- xfloat or array_like
Boundary-layer running length.
- Reinf_Lfloat
Free stream Reynolds number computed at L (length of the flat plate).
- Ts_Tinffloat
Temperature ratio between the reference temperature and the the free stream temperature.
- Trfloat
Recovery temperature.
- Prfloat
Prandtl number.
- kinffloat
Free stream thermal conductivity of the gas.
- epsfloat
Surface’s emissivity.
- sigmafloat, optional
Boltzmann constant. Default to 5.670374419e-08 W / (m^2 * K^4).
- laminarbool, optional
Default to True, which computes the results for the laminar case. Set
laminar=False
to compute turbulent results.- omegafloat, optional
Exponent of the viscosity power law. Default to 0.65, corresponding to T > 400K. Set
omega=1
otherwise.
- Returns
- outfloat or array_like
