Impinging jet have been used in various industry fields, high temperature surface like turbine blade cooling or various material cleaning. Because flow to inject at the jet exit has an influence the other close jet flow, it changes depending on several parameters. In this research if it has multiple jets, not single jet, it is main purpose to find out how to change the flow characteristics depend on various impinging jets configuration in jet flow. It will be considered parameters such as the number of jets and array of jets, distance between the target plate and jets in this paper. The CFD (computational fluid dynamics) was used to model fluid flow.
