Fluids containing floating tiny particles in Nanometer scale, called Nano fluids, have a high potential in heat transfer augmentation. A numerical analysis of heat transfer in jet impingement of Al2O3- Water Nano fluid when turbulence models of spalart-Allmaras, K-ɛ, K-ω and Reynolds Stress are applied is studied. The experimental results found in laboratory for a confined and submerged circular jet impingement for Reynolds amounts of 20000, 40000, 60000 and 80000 when the distance between the nozzle and the wall is remained 2 mm constant is compared with numerical results and the weakness and strength of any of these 4 turbulence models is declared. The best results are found for K-ɛ Realizable and Reynolds Stress models
