Abstract : A method of solving nonlinear problems of high-temperature heat transfer is presented; it is based on the linearization of the basic process equation, starting from the condition of minimum rms error due to violating nonlinearity; in this, the nonlinear boundary conditions are satisfied analytically exactly. Three characteristic stages are considered, corresponding to the kinetics of heating (cooling) of a solid body: the initial period, the quasi-steady-state regime, and the transition region.
