Fundamental Physics Underlying Polymer Drag Reduction, from Homogeneous DNS Turbulence with the FENE-P Model
Reduction in surface shear stress in turbulent boundary layers implies suppression of turbulent momentum flux, a large-eddy phenomenon. The physics by which dilute concentrations of long-chain molecules alter large-eddy structure and momentum flux is not well understood. Experiment, however, indicates an essential mix of turbulent velocity fluctuations, polymer molecules, and mean shear. We stu...
متن کاملPerformance of SST k-ω Turbulence Model for Computation of Viscous Drag of Axisymmetric Underwater Bodies
This paper presents 2-D finite volume method for computation of viscous drag based on Reynolds-averaged Navier-Stokes (RANS) equations. Computations are performed on bare submarine hull DREA and six axisymmetric bodies of revolution with a number of length-diameter (L/D) ratios ranging from 4 to 10. Both structured and unstructured grids are used to discretize the domain around the bodies. Diff...
متن کاملCritical Drag Investigation for an Axisymmetric Projectile with Choked Base Bleed at High-Subsonic and Transonic Regime Using SST K-? Model
In the following paper, the effects of a choked jet exhausted from the base of a non-lifting body on its total and base drags at sub-sonic and transonic regimes has been numerically investigated. Having surveyed the results of some turbulence models and after comparing with experimental results, an appropriate turbulence model i.e. SST K-?, has been chosen and this model has been used in the su...
متن کامل2DV Nonlinear k-ε Turbulence Modeling of Stratified Flows
The commonly used linear k-ε turbulence model is shown to be incapable of accurate prediction of turbulent flows, where non-isotropy is dominant. Two examples of non-isotropic flows, which have a wide range of applications in marine waters, are saline water flow and the stratified flows due to temperature gradients. These relate to stratification and consequently, variation of density through...
متن کاملAssessment of k-ε / EASM Turbulence Model Upgrades for Analyzing High Speed Aeropropulsive Flows*
This paper discusses the numerical simulations of selected high-speed aeropropulsive applications including axisymmetric supersonic base flowfields, with and without jets, and three-dimensional supersonic hot jets. Comparisons are made using a compressibility corrected k-ε turbulence model and an Explicit Algebraic Stress Model (EASM). The present EASM, referred to as EASM/J, has been modified ...
