Abstract

In this paper, a parallel Newton-Raphson algorithm with domain decomposition is developed to solve fully coupled heat, water and gas flow in deformable porous media. The model makes use of the modified effective stress concept together with the capillary pressure relationship. Phase change and latent heat transfer are also taken into account. The chosen macroscopic field variables are displacement, capillary pressure, gas pressure and temperature. The parallel program is developed on a cluster of workstations. The PVM (Parallel Virtual Machine) system is used to handle communications among networked workstations. An implementation of this parallel method on workstations is discussed, the speedup and efficiency of this method being demonstrated by numerical examples.
