Turbulence Modeling of Wall Jets using the Algebraic Structure Based Model

Report PRE-2628. The Algebraic Structure Based Model (ASBM) of Langer and Reynolds (2003) provides an innovative approach for modeling the turbulent stresses, while incorporating information on the structure of turbulence and providing closure for Reynolds-averaged Navier-Stokes equations. The normal turbulent stresses, for which the ASBM has...

Incorporation of the effects of accelerating flow in the design of granular bed protections

For the design of granular bed protections often a stability parameter is used. The stability parameter represents the forces that are acting on the stones and is used to predict the response of the bed to these forces. Existing parameters are often derived for a limited range of application. When the parameter is used outside this range, the...

Turbulence Modeling for Heat Transfer to Supercritical Pipe Flows

In the present work, a comprehensive review on different mechanisms affecting heat transfer characteristics of supercritical flows is carried out. The physical mechanism of heat transfer is then further investigated using inhouse DNS data. In addition, RANS simulations of a heated vertical pipe with supercritical CO2 are carried out using...
