Coolingsystems and channels of a low pressure die casting are critical to obtainbetter mechanical properties. Both steady-state and time-dependent (transient) ComputationalFluid Dynamics (CFD) analyses of the cooling channels and the die coolingsystem, both in conjugate and solid-only models, are performed and the pipeflow part of the results are compared with the available experimental data.Pipes operate at a schedule transiently, therefore a complex time-dependentsimulation is required. The aim is to construct a simplified approach in whichonly the solids (die and cast wheel) are considered and pipe cooling isrepresented by heat transfer coefficient distribution obtained from the muchfaster steady-state simulations. Successful results are obtained bysignificantly reducing the computational time while retaining the same accuracy.Finally, cooling channels with eight different diameter stream-wisedistributions are analyzed to explore their impact on pipe exit velocity andmass flow rate as a guidance towards future works. Wheels are cast with thesimulated cooling system and are approvedby mechanical tests.
