TEMPERATURE FIELD OF A SOLID BODY CONTAINING A SPHERICAL HEATING SOURCE WITH A UNIFORMLY MOVING BOUNDARY
A. V. Attetkov, I. K. Volkov, and S. S. Pilyavskii UDC 536.2 The process of formation of a temperature field in an isotropic solid body containing a spherical heating source with a uniformly moving boundary for the case of realization of nonstationary heat-exchange regimes that lead to the time dependence of the heat-transfer coefficient have been investigated by mathematical-modeling methods. Keywords: solid body, spherical heating source, mobility of the boundary, temperature field, integral transformation. N. É.
