COMPUTER SIMULATION OF FLUID FLOW FILLING DURING MOLD USING FINITE VOLUME METHOD
In this investigation, ^5 2-D Finite Volume Method (FVM) with unstructured triangular mesh is developed to simulate the mould filling process. The simulation of fluid flow and track of free surface is based on the Marker And Cell (MAC) technique. This technique has capability ofhandling the arbitrary curved solid boundaries in the casting processes. In order to verify the computational results ...
متن کاملMOLD FILLING BEHAVIOR OF DOUBLE GATING SYSTEM IN ALUMINUMLFC PROCESS
The mold-filling behavior in the casting of aluminum alloy (A413) using lost foam casting (LFC) was explored. The effects of gate numbers, type of gating and casting thickness on the filling behavior were evaluated. Although, unlike convectional casting process, the gating system showed little effect onfilling ability, casting thickness created a greater effect on the mold filling. In contrast ...
متن کاملMODELING SURFACE TENSION AND WALL ADHESION IN MOLD FILLING PROCESS
Abstract: In this study an algorithm for mold-filling simulation with consideration of surface tension has been developed based on a SOLA VOF scheme. As the governing equations, the Navier-Stokes equations for incompressible and laminar flows were used. We proposed a way of considering surface tension in mold-filling simulation. The proposed scheme for surface tension was based on the conti...
متن کاملFlow Patterns and Water Penetration in Water-assisted Melt Filling Using an Emulated Mold
Water-assisted injection molding (WAIM) provides a new way to produce hollow plastics parts and reduce production costs. The melt flow behavior when applying high pressure water has an important effect on the water penetration length and residual wall thickness of molded parts. So the purpose of this study was to visualize the flow patterns of melt and to characterize the water penetration beha...
متن کاملNumerical Modeling of Mold Filling and Curing in Non-Isothermal RTM Process (RESEARCH NOTE)
Resin Transfer Molding (RTM) is a composite manufacturing process. A preformed fiber is placed in a closed mold and a viscous resin is injected into the mold. In this paper, a model is developed to predict the flow pattern, extent of reaction and temperature change during filling and curing in a thin rectangular mold. A numerical simulation is presented to predict the free surface and its inter...
