Impinging jet technique is widely increasing across the globe due to its ability to produce high heat and mass transfer as compared to other traditional methods. Three cases of impinging jets related to cooling technologies for a gas turbine were investigated. The first case involves a single jet impinging on a flat plate. The second case has an array of jets impinging on a curved surface. The third case deals with simulating impinging jet in crossflow. The first case was used for validation and shows the effect of mesh and inlet boundary conditions. After careful observation, it was seen that at least 15 or more prism layers should be used for these types of simulation. Also, SST turbulence model gives the best output for all the cases discussed below. For the fenot  case, jet-to-jet spacing (P/d) of 4 was observed to give best heat transfer. Turbulence modeling and jet versus crossflow ratio was compared, and passive scalar mixing was performed and was observed that as the crossflow increases, the heat transfer gets worse.
