Carlos Hernán Salinas Lira Multidisciplinarias (Ciencias Sociales) Phase Change Alloy Aluminum Enthalpy Model Natural Convection Finite Volume Method The objective of the present work is to develop a numerical model to analyze melting solidification processconsidering the natural convection phenomena to an alloy metal in a square section. Physical medium istaken as incompressible Newtonian fluid with isotropy thermal properties where the heat is transferred byconduction and convection, including de thermal phase change phenomenon. The last one is modeled bythe improvement procedure, called Enthalpy Model, based on the fraction solid function which liberates thelatent heat according to fraction of solid particles generated using as parameter the temperature level. Themathematical model is based on a non-linear second order differential partial equation system: Momentum,continuity, heat transfer equations and a set of auxiliary expressions with the purpose of equation systemclosure or applied the boundary and interface condition. The numerical model is based on Volume FiniteMethod in body fitted coordinates with a SIMPLER scheme to join pressure and velocities. The strategystudy allows the two-dimensional solidification of alloy aluminum (Non-Isothermal Solidification) in squaresection. Unsteady state results are shown in the way: Streamlines and isotherms compared with available dataafter performing a consistency analysis. 2001 artículo científico 0717-196X https://www.redalyc.org/articulo.oa?id=29901006 en http://www.redalyc.org/revista.oa?id=299 Theoria application/pdf Universidad del Bío Bío Theoria (Chile) Num.1 Vol.10 |
