Methods of the theory of similarity at the processes of hydrodynamics of melts and heat transfer

Abstract

A technique of application of methods of the theory of similarity for calculation of thermal physics of casting processes is suggested. It allows modelling of processes of solidification and cooling of castings from aluminium alloys in metallic moulds. Computation methods for heat transfer at the contact boundary: metallic mould - casting, are developed taking into account the gas gap, which changes in time and space. A similarity equation is obtained for the processes of filling of molds with liquid metal.
