Purpose – To present a numerical model of squeeze casting process. Design/methodology/approach – The modelling consists of two parts, namely, the mould filling and the subsequent thermal stress analysis during and after solidification. Mould filling is described by the Navier‐Stokes equations...
Purpose – To develop a numerical methodology to simulate the lost foam casting (LFC), including the gas back‐pressure effects. Design/methodology/approach – Back‐pressure effects are due to the interactions of many physical processes. The strategy proposed herein tries to model all these...
Purpose – The paper seeks to present an original method for the numerical treatment of thermal shocks in non‐linear heat transfer finite element analysis. Design/methodology/approach – The 3D finite element thermal analysis using linear standard tetrahedral elements may be affected by spurious...
Purpose – This study proposes to develop and investigate different iterative solvers for non‐Newtonian flow equations. Design/methodology/approach – Existing approaches for the time discretization of the flow equation and for an iterative solution of the discrete systems are discussed. Ideas for...
Purpose – The purpose of this paper is to develop a new local radial basis function collocation method (LRBFCM) for one‐domain solving of the non‐linear convection‐diffusion equation, as it appears in mixture continuum formulation of the energy transport in solid‐liquid phase change systems....
Purpose – To present a novel moving boundary problem related to the shoreline movement in a sedimentary basin and demonstrate that numerical techniques from heat transfer, in particular enthalpy methods, can be adapted to solve this problem. Design/methodology/approach – The problem of interest...
