Abstract
The parameters considered for the study for thermo-hydraulic performance comparison Pressure drop, temperature difference, heat transfer coefficient and heat flux using LMTD analysis. The numerical results indicate that the pressure drop shows a big difference among the three patterns and is maximum for Triangular Pattern, the overall heat transfer coefficient is higher for rotated square pattern design, turbulent kinetic energy is maximum for the square pattern tube arrangement helps to create a turbulence flow of a fluid which in turn increases the heat transfer efficiency and for high difference in between hot and cold fluid inlet temperature rotated square pattern tube arrangement shows high heat flux, while at lower difference it is almost same for square and rotated square pattern tube arrangement.
