Abstract

Steady state numerical simulations were carried out with twisted tapes on shell side of a shell and tube heat exchanger. Thermal hydraulic performance of a heat exchanger with various twisted tape widths and twist ratios was conducted. The effects of structural modifications were investigated on the heat exchanger performance. Limited lab-scale experiments, using water as working fluid, were carried out to validate the numerical simulations. The entire model meshing method was adopted to mesh the geometry with Gambit 2.4 software while k-εrealizable model was adopted. Combining effects of both the geometric and structural modifications, an improved design with optimum comprehensive performance was suggested.
