Numerical Study on Effect of Inclination of a Plane on Flow and Heat Transfer by Turbulent Wall Jet

In this chapter, the heat transfer characteristics of a turbulent wall jet impinged on an isothermal inclined surface has been numerically investigated. Three different angles of inclinations ( \(\alpha\)  = 3°, 6° & 9°) as well as a streamwise orientation of the plane have been considered. All the simulations have been done using Realizable k-ε Model with Enhanced Wall Treatment assuming zero pressure gradient. The Jet is ejected with Reynold’s Number 9600. A localized gain in the local maximum velocity over the jet exit velocity is noticed at the leading edge of inclination which enhances the local heat transfer coefficient. However, the jet self-similarity character remains undisturbed due to inclination. Total heat transfer from the surface as well as the average heat transfer co-efficient decreases slightly with increase in inclination of the plane.
