Heat transfer coefficient and ζ

  1. Dec 12, 2014 #1
    How do I find the heat transfer coefficient for a meteorite?
    The meteorite is made of carboneus chondrite, but approximations with heat transfer coefficients for regular stones or rocky materials would be just as fine.

    Furthermore, how would I calculate the energy required to vaporize 1 g of meteoric material, if the meteor had an initial temperature of 200 K? I haven't been able to find anything about at with temperature stones would evaporate (or if it's even possible for them to?) or their specific heat of vaporization.

    This is what I know:
    • Stony meteorite, specific heat: c_sm = 1.2 * 10^3 J kg^-1 K^-1
    • Stony meteorite, thermal conductivity: k_sm = 2.0 W m^-1 K^-1
    • Stony meteorite, density: p_sm = 3.3 * 10^3 kg m^-3
    • Stony meteorite, melting point: T_sm = 1.7 * 10^3 K
    • Stony meteorite, specific melting heat: L_sm =2.6 * 10^5 J kg^-1
    Any help would be greatly appreciated!

    Possibly Google the word ablation.
