Turbulent Flow in 2-D Domains with Complex Geometry-Finite Elelment Method

Using the highly recommended numerical techniques, a finite element computer code is developed to analyse the steady incompressible, laminar and turbulent flows in 2-D domains with complex geometry. The Petrov-Galerkin finite element formulation is adopted to avoid numerical oscillations. Turbulence is modeled using the two equation k-ω model. The discretized equations are written in the form o...

A novel method for calculating free energy difference between systems

Calculating free energy differences is a topic of substantial interest and has many applications including chemical reactions which are used in organic chemistry, biochemistry and medicines. In equilibrium free energy methods that are used in molecular simulations, one molecule is transformed into another to calculate the energy difference. However, when the compared molecules have different nu...
