Impinging of axisymmetric developing jets

WitrynaAn impinging cooling system comprises a jet of high-velocity fluid striking a hot target surface. The fluid jet picks up thermal energy from the hot surface, thus enhancing heat transfer from it. During this process, thermal energy is transported from the hot surface to the fluid via forced convection, raising the fluid temperature in the ... http://s177835660.websitehome.co.uk/research/THESIS/imp_jet.pdf
