Short Communications Temperature Profiles in Some Heat Conduction Problems with Spherical Symmetry
A Brown, GL Downes · Australian Journal of Physics · 1970
Temperature profiles are known for several composite systems involving a sphere losing heat into an infinite surrounding medium. Lovering (1935, 1936) considered the diffusion of heat from a sphere into a cooler medium with the same thermal properties, i.e. the same conductivity K and diffusivity k. The initial temperatures of the two bodies were assumed constant.
