1. 1. Experimental validation of a periodic heat transfer CFD model of a vertical shell and tube heat exchanger

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Patrik Bengtsson; Dilip Kumar Vellore Saikumar; [2019]
   Nyckelord :;

   Sammanfattning : Flow obstructions are used as a passive design element in heat exchangers to enhance heattransfer. Further, a change in flow structure can also have a positive effect on the heat transfer. Avertical shell and tube heat exchanger, used to recover heat in the greywater stream, isinvestigated in this study. LÄS MER
