Abstract

Present study is focused on numerical investigation of heat transfer and fluid flow from a heated surface by using nanofluids and impinging jets. Effects of Reynolds number, different particle diameter and different types of nanofluids (TiO 2 -water, CuO-water, NiO-water) on heat transfer and fluid flow were studied numerically. TiO 2 -water nanofluid was used as a base coolant. Three impinging jets were used to cool the surface. It is obtained that increasing jet velocities from Ren/Re1=1-1.33-1.67 to Ren/Re1=1-1.20-1.40 causes an increase of 49.9% on average Nusselt number (ANN) but increasing jet velocities from Ren/Re1=1-1.20-1.40 to Ren/Re1=1-1.17-1.33 causes a decrease of 4.6% on ANN. Particle diameter from Dp=80nm to 10nm causes an increase of 2.9% on ANN. Using NiO-Water nanofluid causes an increase of 1% on ANN with respect to CuO and 2.8% with respect to TiO 2 -water. Low Re k-ε turbulent model of PHOENICS CFD code was used for numerical analysis. Numerical results show a good approximation to experimental results.
