Thermal Performance Evaluation of Inserting Inserts in Evaporator Tube Analytically

Abstract

In this thesis, the main aim is to evaluate the heat transfer performance of tube evaporator by taking inserts. Comparisons are made between the evaporator with external insert and internal insert. The inserts considered are twisted tape inside the tube and wire coils for outside the tube. The effect of varying the Reynolds number is also investigated.3D models are done in Creo 2.0. CFD analysis is done in Ansys. Analysis is performed for two models of tube evaporator twisted tape and wire coil inserts, varying Reynolds number 6000, 8000 for different refrigerants R32, R152A, R600A to determine heat transfer coefficients and heat transfer rates
