A meshless method for predicting two dimensional flow front advancement and its application in injection moulding

Flow front advancement is a common phenomenon in many industrial process simulations, which are important in designing tools for these processes. The advancement is traditionally simulated by performing numerical computation in a meshed flow domain with a known velocity field. Since the design process is iterative, the costs of performing detail simulation in all iterations are high. This paper presents a meshless approach to simulate the flow front advancement in a bounded domain. The computation efficiency of this approach is raised because part of it is handled by a solid geometry kernel and the costs are further reduced by an estimated the velocity field. The generated flow front pattern is useful in preliminary analysis. An engineering example in injection moulding is raised to demonstrate the application.
