SOLUTION METHODOLOGIES FOR DIRECT AND INVERSE PROBLEMS OF HEAT AND MASS TRANSFER ON THE BASE OF THE ANALYSIS OF CHARACTERISTICS OF IMAGINARY FREQUENCES FOR TRANSFER FUNCTIONS

Mathematical modelling and calculation experiment have been held in the paper. The region of the rule applicability for the Laplace transform operator "transfer" under the function sign has been investigated. Applicability boundaries for the method of imaginary frequency characteristics have been extended. The effective algorithm for the solution of inverse problems of heat and mass transfer has been obtained. The durability estimation of a steam gas generator, a separator-steam superheater, tubes of the cleaning and cooling block has been held. It has been shown, that the account of the mass exchange coefficient non-stationary is necessary at the calculation of drying regimes. The methodology for the calculation of heat transfer inverse problems has been introduced into operationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
