DETERMINATION OF TEMPERATURE DISTRIBUTION IN WOOD WITH VARIABLE SURFACE TEMPERATURE BY NUMERICAL INTEGRATION OF DUHAMEL'S INTEGRAL.

Abstract

A numerical method is developed to determine the temperature distribution in homogeneous semi-infinite or thick-walled solids when the temperature of one surface varies with time. A computer program is given in 'FORTRAN' language for the determination of the temperature distribution in the solid and illustratively applied to wood that is subjected to standard fire conditions (ASTM E-119) at the surface. The results are presented graphically. It appears that the method developed can be applied with confidence to surface time-temperature functions of other materials. (Author)
