Abstract : The problem of determining the temperature field in a two-layer wall of a section of a structure that is filled with liquid or gas is examined. On a definite part of the surface of the section, where intensive heat exchange with the external medium occurs, the coefficient of heat exchange from forced convection and the temperature of the external medium are calculated by known time functions. The radiation of heat from the external surface into the external space is calculated. An approximate analytical solution obtained on the basis of a number of assumptions is presented in tabulated functions of the arguments of time and the coordinate along the wall thickness. (Author)
