Abstract:

In the present review the analysis on the helical coil heat exchangers is done by ansys fluent. Its main aim is to study the effect of providing baffles on the helical coil heat exchangers. For study, a three dimensional helical double tube heat exchanger is considered; baffles are provided in annular space between these two tubes. The geometry is modelled using ansys design modular. The analysis is done on counter flow configuration with different thickness of baffles and different curvature ratio (D/d). Also we considered laminar and turbulent case for study. The variation of Nusslet number with different Reynold number and with different baffle thickness is plotted. It is found by study that on increasing the baffle thickness up to a certain limit Nusselt number increases, also it is found that on increasing curvature ratio Nusselt number decreases.
