Variational solutions of complex heat and mass transfer problems

摘要: Publisher Summary The development of quantitative methods for complex phenomena heat and mass transfer requires accounting all important aspects that correspond to the real progress processes. This imposes certain difficulties, such as dependence thermophysical properties body material or moving medium on problem arguments, is, coordinates point time. However, an exact analytical solution problems in a linear case nonlinear is impossible general presence complicating factors acting either jointly separately. Therefore, analyze these phenomena, it necessary develop effective would possess main property solutions, parametrization admits representation, analysis simplicity calculations. A variational description using convolution-type functional, while providing mathematical equivalence initial boundary-value corresponding problems, very solving conduction.
