Original Abstract

An initial phase in the development of a modelling approach to analysing fluid flow and heat distribution in specific heat transfer equipment is presented. A steam superheater as a typical heat exchanger operated in process and power industries is used to introduce the aspects of modelling of this phenomenon. The particular parts of the superheater where problems can be expected are described in order to propose a suitable calculation method which would be applicable to equipment with complex technological and geometric design. Available modelling techniques and approaches are reviewed and applied to the discussed apparatus with distinguishing multiple-channel design and their advantages and limitations are identified. Based on this analysis, principles of a new modelling method are outlined. The proposed modelling method employs a combination of simplified approaches to 1D investigating the flow distribution and 2D analysis of heat transfer in the cross-flow heat exchanger. Additionally, future development of the intended fast yet accurate-enough method for prediction of fluid flow and heat flux distribution in the specific heat exchanger is suggested.
