Significance of Baffles in Fluid Flow and Heat Transfer
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 8
Abstract
In the field of fluid flow and heat transfer utilization of complex geometries in from of extended surface such fins, baffles, artificial roughness gaining attention of researchers due to having significant application in the field of heat and mass transfer, specially baffles are exercised in various thermal application in order to increase thermal performance and hydrodynamic performance characteristics. . Application such as Heat exchanger, solar air heater, photovoltaic ducts or channel, nuclear reactor etc. these baffles leads to obstacle in flow through which turbulence generates which help in promotion of fluid mixing, heat transfer, enhancement un friction factor etc. This work focuses on hydrodynamic performance analysis of pipe with presence of fragmented baffles. The performance characteristics of baffled pipe have been compared with smooth pipe for a wide range of Reynolds number. The governing equation has been solved by using ANSYS Fluent and for high Reynolds number k-turbulence model has been used along with SIMPLE algorithm. The obtained results have been compared with available literature and show good agreement with the computational an experimental work.
