“…Polat et al [2] published a comprehensive review on the numerical analysis of impinging jet flow and heat transfer prior to 1989. Among the recently published studies on jet impingement cooling, the works of Seyedin et al [1], Morris et al [3] Morris et al [4], Cziesla et al [5], Shi et al [6], Sahoo and Sharif [7] can be mentioned. This list, however, is not comprehensive by any means.…”

“…The heat transfer coefficient for these typical applications using impingement jet is found to be higher than that of a cross circulation dryer for the same amount of gas flowing parallel to the target surface [1]. Hence, impinging jets are used in paper and textile industries where the thermal treatment of materials, cooling of electronic components and turbine blades, and drying of continuous sheets of materials, etc.…”

“…The calculated results show that the size and location of the recirculating zones around the jets are different from the two dimensional flow fields due to the effect of stretching in the transverse direction. Seyedein et al [20] used the numerical method to simulate the two dimensional turbulent flow and heat transfer from confined multiple impinging slot jets. Xing et al [21] conducted a combined experimental and numerical investigation of the heat transfer characteristics within an array of impinging jets.…”

“…Chatterjee and Deviprasath [32] demonstrated that the off-stagnation point maxima of Nusselt number are entirely a consequence of upstream flow development because of vorticity diffusion. Numerical investigation of heat transfer rate using various k-models [34][35][36][37] has been carried out. Hosseinalipour and Mujumdar [35] compared the one standard and five low Reynolds number (LRN) versions of k-turbulence models to predict the heat transfer characteristics of confined turbulent single impinging and opposing slot jet flows.…”

SUMMARYSpray impingement has been a major interest of researchers in the areas of spray cooling, internal combustion, fire suppression and spray cooling, etc. for a long time. Numerous studies have been done in the area of spray cooling. Spray cooling with phase change takes advantage of relatively large amounts of latent heat and is capable of removing high heat fluxes from the surface, which has generated the interest of many researchers. In this paper, the turbulent characteristics of vapor formed during the spray impingement are studied. Water and gasoline are used in the numerical analysis of the two-phase spray impingement on a heated wall. Hybrid turbulence modeling was used for the analysis where the subgrid scale model was employed away from the wall and k-model was used near the wall. Gasoline, at 298 K, was sprayed on the heated wall, kept constant at 650 K. The surrounding temperature was maintained at 400 K at the start of the simulation. In case of water and gasoline at Reynolds number 2750, the heated wall was kept constant at 400 K and the surrounding temperature was maintained at 298 K at the start of the simulations. The nozzle diameter of 100 m was used for this study, with the nozzle plate spacing ratio at 10. The spray was impinged on the flat plate at angles of 0, 15, and 30 • . Root mean-squared velocities and turbulent heat flux were plotted in the water spray impingement for the different angles of impingement. The effect of turbulence on the heat transfer was observed. The effect of vortex motion on the turbulent heat flux values was analyzed using different Reynolds numbers of impingement and at different angles in case of gasoline. The turbulent heat flux attained the maximum values with high vortex formation. Upwash of fluid transported heat away from the wall, producing higher heat flux values in the region.
