Quenching of a composite slab

Abstract

A solution by the Wiener-Hopf technique is derived for a model which describes quenching of a composite, infinitely long slab, including an imperfect contant between the laminates. On the wetted side upstream of the quench front a constant heat transfer coefficient is assumed, whereas the dry downstream region is supposed to be adiabatic, and likewise the unwetted slab. The quench front temperature is presented in the form of an integral whose integrand contains the model parameters, including the quench front velocity, It is shown that there are such large values of the quench front temperature and the gap resistance, or such low values of the initial wall temperature, for which the quench front velocity is unaffected by the properties of the unwetted slab.
