“…Among them, the inclined jet impingement angle was the focus of many reports studying changes of the heat transfer parameters. [11][12][13][14] The results showed that the region of maximum heat transfer shifts toward the uphill side of the plate, and the maximum Nusselt number decreases as the inclination angle decreases.…”

“…Choo et al [7] experimentally investigated thermal characteristics on a flat plate and showed that the governing parameter of the heat transfer is stagnation pressure. Bieber et al [8] numerically investigated the submerged laminar slot jet impingement. They suggested correlations for submerged slot jets as functions of nozzle-to-plate distance, heat flux, and wall temperature.…”

Heat transfer and fluid flow characteristics of air-assistant submerged and free surface water impinging jets are experimentally investigated. Results showed that the Nusselt number and pressure decrease exponentially in both free surface and submerged jets for all volumetric qualities in jet deflection region. In transition region, the Nusselt number and pressure of the submerged jet and free surface jet decrease since the jet deflection effect was disappeared. In buoyance effect region, the Nusselt number and pressure increase in the free surface jet since the potential energy increases, while the Nusselt number and pressure decrease in the submerged jet since the bubbles are not impinged the plate due to the buoyancy effect.

“…It appears shear layer around the jet flow. Therefore, the fluid around the jet flow is accelerated by momentum transfer to surrounding affects to increase mass flow in the jet [11]. Both types of jet flow have impingement region and wall jet region characteristics when its impact on the surface.…”

The effect of adding air into water jet flow for heat transfer enhancement was investigated for submerged impinging jet. The Reynolds number of water jet was fixed at ReL = 2.4x10 4 , the nozzle to impingement surface distance was also fixed at L = 2D, and the volumetric fraction was varied from = 0.0 to 0.7. The heat transfer measurement was studied using an infrared thermal imaging camera. The flow behavior of bubbly jet was observed by a high-speed camera. The result showed that the heat transfer of the bubbly jet for all cases were higher than the water jet case. The average Nusselt number on surface was continuously increased for increasing volumetric fraction = 0.0 to 0.2. It was found that the volumetric fraction at = 0.2 gave the maximum heat transfer enhancement about 33% compared to case of water jet. But the increase of volumetric fraction in range = 0.2 to 0.7 decreased the average Nusselt number.
