Turbulent flow and heat transfer measurements on a curved surface with a fully developed round impinging jet

Transport phenomenon in a jet type mold cooling pipe

“…J  D C y (6) J is proportional to the difference in concentration between the electrode surface and the fluid body, and is given by the following formula. The current obtained with diffusion control is defined as the limiting current I d .…”

“…To optimize heat transfer, an understanding of the temperature field as well as the velocity field is essential, in particular near the impingement surface where the flow characteristics dominate the heat transfer process. Heat transfer distributions of jet impingement and the effect of various geometric and flow parameters on heat transfer are well documented, for example by Miranda and Campos [1,2], Kayansayan and Kucuka [3], Hrycak [4], Gau and Chung [5] and Lee et al [6].…”

Study on Impingement of Air Jet from Orifice on Convex Surface for Unconfined Flow

“…Lee et al [5] done experiments on convex surface with low relative curvature (d/D = 0.034-0.089) for Re = 11000-50000 using liquid crystals to measure the local surface temperature. They came to conclusion that the Nusselt number increases with increasing values of curvature at stagnation point.…”

Heat and Mass Transfer in Jet Type Mold Cooling Pipe

“…To optimize heat transfer an understanding of the temperature field as well as the velocity field is essential, in particular near the impingement surface where the flow characteristics dominate the heat transfer process. Heat transfer distributions of jet impingement and the effect of various geometric and flow parameters on heat transfer are well documented, for example by Miranda & Campos (1999, Kayansayan & Kucuka (2001), Hrycak (1981), Gau & Chung (1991) and Lee et al (1997). Jet cooling pipes are used across a wide range of temperatures in die cooling, probes for cryogenic surgery and other applications.…”
