A comparison is made of two different methods of calculating transient temperatures for thick walls with arbitrary variation of heat-transfer coefficient and adiabatic-wall temperature. Although numerical calculations for special cases for which the exact solutions are available show that both methods give satisfactory results, Hill's method (NACA Technical Note 4105) consistently gives nearly exact results with considerably less computing time, except for the case in which a temperature profile through the thick skin is desired.
