Research Interests

  • We develop novel numerical methods to simulate the fluid flows over surfaces. The developed methods are based on Discrete Exterior Calculus (DEC), which is an alternate language to express the tensor differential operators; e.g. gradient, curl, divergence, .. etc. The application of the DEC operators helps the discretization to preserve the key physical quantities that their preservation is implied in the continuous governing equations. Examples for these preserved physical quantities for the incompressible Navier-Stokes flows are the mass, the vorticity and the kinetic energy.
  • We develop conservative discretizations of the incompressible Navier Stokes equations on surface simplicial meshes using Discrete Exterior Calculus (DEC). The memitic behavior of the DEC operators enables the discretization to preserve the flow key physical quantities; e.g. the mass, the vorticity and the kinetic energy. We also explore novel physical phenomena of the flows over curved surfaces using the developed discretization.
