文摘
The work proposes a set of empirical equations for the prediction of impinging jets. Correlations cover a large range of flow conditions and jet configurations. Wall shear, Nusselt number, wall temperature and velocity distributions are provided. Temperature profile at the wall jet region is described as a Weibull distribution. Jet properties are determined in terms of gross parameters of the flow.
