Reference value alpha0 for nucleate boiling of pure substances (HABA)

HABA module

The program calculates the reference value α₀ for nucleate boiling of pure substances (pool boiling, flow boiling of saturated liquids) for

P_r = 0,1 , q₀ = 20000 W/m² and Ra,₀ = 10^-6 m

Only the critical data (P_c, T_c, v_c), the molar mass M, the boiling temperature at P_r = 0,1 and the specific heat capacity at this temperature are required for the calculation.

These properties can either be transferred from the PROPER properties generator or entered freely.
