The aim of the project is to develop efficient and stable numerical methods for calculating the dynamic characteristics that are necessary for the selection of rational schemes of automatic control of thermal systems of modern energy technology installations . A new method for the analysis of nonstationary processes of recuperative heat exchangers has worked out. Application of a method of the running calculation for the solving of the differential equations of mathematical model connected in system, represents the scientific novelty of this research work. The resulting algorithm for analysis of the heat exchanger based on the finite-difference equations has been investigated on the stability and convergence. Absolute stability and high convergence allow to apply the method to analyze the dynamics of plate and tubular heat exchangers with a complex scheme of coolant flow under the various laws of change of temperature flux at the entrance to the unit. The results of the project can be applied in heat power system, power engineering, chemical engineering, petrochemical production and other industries. Product Description popup.authors Абдулин С.Ю.
