Development of Heat and Fluid Flow Distribution Modelling System for Analysing Multiple-Distributed Designs of Process and Power Equipment

Abstract

More accurate modelling of heat and fluid flow distribution in apparatuses grows in importance due to ever-increasing demands on process and power heat transfer equipment such as heat exchangers, tubular furnaces, or steam boilers. The paper gives an overview of the currently available calculation methods and approaches to predicting and analysing flow behaviour and heat distribution in the most important types of process and power equipment. Properties, possibilities, and limitations of the individual calculation methods are discussed. Based on the analysis, the main findings from the development of the heat and fluid flow distribution modelling system for analysis of process and power equipment with multiple-distributed designs are presented. The proposed modelling conception is illustrated by employing an industrial case of an operated steam superheater with a specific multiple-distributed design. Additionally, future development of the intended fast yet accurate-enough modelling system for prediction of fluid flow and heat distribution is suggested.
