NUMERICAL ANALYSIS ON THE HEAT TRANSFER AND FLOW IN THE SHELL AND TUBE HEAT EXCHANGER

Shell & Tube 열교환기 Shell 측 열전달 및 유동에 대한 수치해석

The numerical simulations on the heat transfer and flow field were carried out for the improvement of the performance of the shell and tube heat exchanger. The steady incompressible 3-D Navier-Stokes solution is obtained with the actual operational condition and geometry of the heat exchanger. The present geometry of the heat exchanger causes poor heat transfer since the air inside shell dose not flow through the tube bundle, but around it. The enhancement of the heat transfer can be achieved by the variation of the design factor like the sealing strip located on the top/bottom and middle of the baffle.
