Residual-based variational multiscale modeling in a discontinuous Galerkin framework

In this work the residual-based variational multiscale method is presented in a discontinuous Galerkin framework. This so-called ‘DG-RVMS’ strategy is developed, extensively verified, and tested on a more complex case.<br/><br/>The proposed DG-RVMS paradigm consists of three principle components. First, the perelement weak form is coupled by...

Development of a Two-Scale Turbulence Model and Its Applications

The use of second order closure turbulence model in predicting turbulent flows is known to be more successful than the classical mixing length model. However, it is found that if the turbulence constants are not altered or modified, the second order closure turbulence model is unable to predict satisfactorily f or some flows such as round jet...
