This work presents the combined experimental and numerical technique to estimate the heat flux in the metal quenching process by array of jets. Experimental techniques are explained for the measurement of temperature. A two-dimensional inverse heat conduction problem (IHCP) is solved through the Ling et al. [Ling, X., Keanini, R.G., Cherukuri, H.P., 2003. A non-iterative finite element method for inverse heat conduction problems. International Journal for Numerical Methods in Engineering 56 (9), 1315–1334] non-iterative finite element method (FEM) using the experimental temperature data. Wetting front which separates the film boiling and nucleate boiling zone, changes the order of the heat flux. Maximum heat flux position and its propagation velocity are plotted as a function of time. It is demonstrated that increase in water velocity decreases the maximum heat flux and delays the wetting front movement.
