Rate of Heating on an angle

  1. Jun 23, 2010 #1
    I was wondering if anyone knows of an equation that will properly calculate the rate of heating on any material, at any altitude, at any speed, and with air hitting that surface at any angle.

    The equation will be somewhere similar to
    Tr=T0(1+0.2rM^2) where r=recovery factor~0.84 for laminar air flow~0.89 for
    turbulent air flow
    Tinitial=initial temperature
    x=boundary layer distance from the nose
    ρ=density of fluid
    V=mean fluid velocity
    L=travel length of fluid
    μ=the dynamic viscosity of the fluid
    c=specific heat

    However, this equation is for (specifically) heating on a thin rocket airframe.

    Any help would be greatly appreciated.
