The ASBM-SA turbulence closure: Taking advantage of structure-based modeling in current engineering CFD codes
(2015)Structure-based turbulence models (SBM) carry information about the turbulence structure that is needed for the prediction of complex non-equilibrium flows. SBM have been successfully used to predict a number of canonical ...

Direct numerical simulation of particle laden flow in a human airway bifurcation model
(2016)During the delivery of inhaled medicines, and depending on the size distribution of the particles in the formulation, airway bifurcations are areas of preferential deposition. Previous studies of laminar flow through airway ...

Fully turbulent flow in a physiologically realistic human airway bifurcation
(TSFP-9, 2015)Recent computational studies have shown that the airflow in the upper human airways is turbulent during much of the respiratory cycle. A feature of respiratory airflow that poses a challenge to computations based on ...

A grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003
(2008)Computational complexity theory inspires a grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003. A novel complexity analysis estimates that structured programming time grows at least quadratically with ...

A spectral domain decomposition approach for steady Navier-Stokes problems in circular geometries
(1996)In this study, a spectral collocation domain decomposition method is developed for the numerical solution of second and fourth-order problems in circular domains. The method is applied to the Navier-Stokes equations and ...

Spectral element discretization of the circular driven cavity. Part IV: The Navier-Stokes equations
(2004)This paper deals with the spectral element discretization of the Navier-Stokes equations in a disk with discontinuous boundary data, which is known as the driven cavity problem. The numerical treatment does not involve any ...
