Numerical Modelling of Pure Metal Solidification using numerical and experimental investigations for hot metal

Till date, numerous numerical investigations have been conducted to explore the flow-patterns due to the thermal convection during the solidification of pure metals. In the earlier numerical models, the different set of governing equation were used in the solid and liquid region to study the solidification behavior [1,7,9]. This type of model-Numerical Investigations of Quenching Cooling As the time proceeds, the hot surface temperature drops and the heat flux increases. When the wall heat flux reaches the maximum heat flux or the so-called critical heat flux, the nucleate boiling regime is entered. There the vapour film becomes unstable and starts to disappear. This results in a higher heat transfer rate between the metal and theNumerical Analysis of the Effect of Sinusoidal Pressure numerical and experimental investigations for hot metalNumerical Analysis of the Effect of Sinusoidal Pressure Path on Thinning of Tube in Hot Metal Free Figure3.
