Heat Transfer Enhancement in Circular Wavy Grooved Surface Tube Using Alumina-Water Nanofluid
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 6
Abstract
In this paper the computational analyses of circular wavy grooved surface using alumina nanofluid has been carried out to simulate the fluid flow and heat transfer characteristics for turbulent flow models using ANSYS 15.0. The flow of fluid is assumed to be incompressible, steady and turbulent with constant thermo physical properties. The flow is studied for Reynolds number 3980 to 119425 with constant boundary conditions. The Navier Stokes equations along with the energy equation have been solved by using SIMPLE Technique. The standard k-ϵ turbulence model is used for simulation of fully developed turbulent flow. First, the simulation is done on the simple tube and then the tube is replaced by the circular wavy grooved surfaced tube with same diameter and length and then it is simulated. Then finally the effect of alumina nanofluid is investigated for the same boundary conditions. The result shows 55% to 93% increase in nusselt number and with the use of circular wavy grooved surface and it further enhances with the use of nanofluid. There was also a huge drop of pressure due to use of circular wavy grooved surfaced tube.
