Large Eddy Simulation of Turbulent Flow and Heat Transfer in a Ribbed Coolant Passage

Numerical simulations of hydrodynamic and thermally fully developed turbulent flow are presented for flow through a stationary duct with periodic array of inline transverse rib turbulators. The rib height to hydraulic diameter ratio e/Dh is 0.1 and the rib pitch to rib height ratio P/e is 10. The effect of secondary flow due to presence of rib turbulators on heat and mass transfer has been inve...

Large eddy simulation of compressible turbulent pipe flow with heat transfer

A compressible finite volume formulation for large eddy simulation (LES) of turbulent channel flows was extended to solve the turbulent flows in pipes and annular passages. A general finite volume scheme was developed based on conservation equations in Cartesian coordinates with non-Cartesian control volumes. A dual-time stepping approach with time derivative preconditioning was employed and ti...

A fractal model for large eddy simulation of turbulent flow

A new class of subgrid closures for large eddy simulation (LES) of turbulence is developed, based on the construction of synthetic, fractal subgrid-scale fields. The relevant mathematical tool, fractal interpolation, allows to interpolate the resolved velocity with fields that have fluctuations down to much smaller scales and to compute the required stresses explicitly. In one dimension, the ap...
