Parallel computation of pollutant dispersion in industrial sites

Understanding the pathway of toxic air pollutants from their source is essential to government agencies that are responsible for the public health. CFD remains an expansive tool to evaluate the flow of toxic air contaminants and requires to deal with complex geometry, high Reynolds numbers and large temperature gradients. To perform such simulations, the compressible Naviers Stokes equations are solved with a collocated finite volume method on unstructured grid and the computation speed is improved as a result of parallelism.
