Thermal-hydraulic calculation and stress analysis of a heat exchanger

Abstract

Hlavn­m pedmÄtem prce je napÄov analza urÄitch Äst­ trubkov©ho vmÄn­ku tepla pouit­m MKP. Kad Äst je posouzena dvÄma odlinmi vpoÄtovmi zpsoby. Zpsobem na zkladÄ vpoÄtovch hodnot a zpsobem bl­­c­ho se skuteÄnm podm­nkm provozu za­zen­. K pibl­en­ se skuteÄn©mu zat­en­ jsou v prci provedeny zkladn­ vpoÄty pestupu tepla pro cel© za­zen­ a pro analyzovan© Ästi jsou vypoÄteny souÄinitele pestupu tepla pomoci CFD.Main object of the work is stress analysis of specific parts of tube and shell heat exchanger by using MKP. Each part is judged by two different computation methods. The method based on computation values and the method nearing real condition of operation of device. To approach real load are in the work made basic heat transfer computations for entire device and for analyzed part are computed boundary conductance by using CFD.
