Current Research 

I am working in the study of 3D scour processes due to structures in presence of waves. For doing this I am writing a code that implements the Favre averaged, two-phase flow equations. These equations assume two miscible, continuous phases interacting by means of buoyant and drag forces. The sediment phase is modeled using the kinetic theory of dense gases. The numerical model is based on Los Alamos' TRUCHAS (originally a 3D, VOF RANS model) to which I have done the necessary modifications to include the two phases and additional terms.

Research Interests 

  • Sediment transport, specifically transient scour in structures driven by waves
  • Two phase flows
  • Numerical methods.

Previous Works 

  • Development of SMC, a CAD-like program for coastal engineering. 
  • Development of MANOLO, a model that solves the extended, weakly non linear Boussinesq equations, based on a program developed at Cornell by Seung B. Woo, a former student of Phil Liu. 
  • Modification of COBRAS (2D Cornell VOF RANS model) so it can be used in real engineering applications.
