Abstract CTS-9809516 G. F. Pinder, U. of Vermont This is a collaborative project between research groups at the University of Vermont (Prof. G. F. Pinder) and the Autonomous University of Mexico (Prof. I. Herrera) in the area of multiphase flow simulation in porous media. Transport of non-aqueous phase fluids will be simulated using finite element method and collocation method with a new interpolation approach based upon splines under tension. The resulting set of algebraic equations will be solved using the conjugate gradient method based upon the optimal location of the collocation points. The method will allow for simulations of flows with sharp fronts and use of parallel processing algorithms. The collaborative project will include the professors and their students. This project was awarded as part of the NSF-CONACyT initiative. The collaboration will contribute to the development of long-term US-Mexico research collaboration in the area of computer simulation and environment (underground contaminant transport).

摘要CTS-9809516 G. F.平德，美国佛蒙特 这是佛蒙特大学研究小组之间的一个合作项目（G。F. Pinder）和墨西哥自治大学（I. Herrera）在多孔介质多相流模拟领域的研究。 非水相流体的输运将采用有限元法和配点法，并采用一种新的基于张力样条的插值方法进行模拟。 将使用基于配置点的最佳位置的共轭梯度法来求解由此产生的代数方程组。 该方法将允许模拟具有尖锐前沿的流动并使用并行处理算法。 合作项目将包括教授和他们的学生。 该项目是NSF-CONACyT倡议的一部分。 这项合作将有助于发展美国和墨西哥在计算机模拟和环境（地下污染物运输）领域的长期研究合作。
