Математическое моделирование образования отложения на поверхности теплопередачи пластинчатого теплообменника

Abstract

The mathematical model of plate heat exchanger (PHE) with fouling deposition on heat transfer surface is presented. The model is accounting for the change of process parameters along the channels length and in time with the development of fouling deposition layer. The model’s parameters were identified using data of monitoring the thermal performance of PHEs operating in industry and District Heating. The model can be used to simulate thermal performance of PHEs working with specific media and to analyze the influence of plate’s corrugation geometry, temperature program and flow velocity in channels on PHE thermal performance in conditions of fouling.
