摘要：

An hp-adaptive Finite Element Model (FEM) coupled with a Lagrangian Particle Transport (LPT) technique is used to simulate contaminant dispersion for emergency response assessment. The adaptive FEM accurately predicts air flow utilizing mesh enrichment along with increasing element order at locations where flow features change greatly. The use of LPT permits particles to be easily employed for predicting contaminant transport. The hybrid numerical model runs on an 18-node Beowulf PC cluster using Linux. Solutions are generally obtained quickly. The model is well suited for emergency response dispersion predictions and assessment.
