NUMERICAL STUDY OF HEAT TRANSFER AND FLUID FLOW IN A CONFINED PLANE TURBULENT JET IMPINGEMENT USING NANOFLUIDS
Keywords:
impinging jet, heat transfer enhancement, nanofluidsAbstract
This article presents a numerical investigation on heat transfer and fluid flow of a confined plane turbulent nanofluids jet impingement on an isothermal heated surface using single-phase model. The finite volume method and standard k-e turbulent model were used for the solution of resulting governing equations. Al2O3 nanoparticles dispersed in water with volumetric concentration of nanoparticles ranging between 0 and 4% were used as working fluid for simulating the heat transfer and fluid flow of nanofluids jet impingement. At inlet mean velocity profile was non-uniform. The influences of volumetric concentration of nanoparticles, aspect ratio and Reynolds number were examined and discussed in details. The results indicated that the volumetric concentration of nanoparticles, aspect ratio and Reynolds number enhance heat transfer when considering in terms of the local and average Nusselt number, while the skin friction coefficient profile is slightly increased whereas increasing the volumetric concentration of nanoparticles.
