Computational Fluid Dynamics Analysis

A computational fluid dynamics analysis of steel plate using volume of fluid multiphase model moving at different velocity i.e. 0.1 to 1 m/sec with 0.1 m/sec interval. From the above concluding points it has been observed that heat flux increased for the steel plate moving at 0.1 m/sec. During quenching process the surface heat transfer coefficient increases at first. And when plate surface temperature is nearly 420 oC, surface heat transfer coefficients reach the maximum value of about 15000 W/(m2K). And then, The calculated heat transfer coefficients are applied to analyze plate temperature field of different thicknesses, and the difference between the calculated and measured temperature is less than 35 %.
