Acceleration-driven variable- density turbulent flow
نویسندگان
چکیده
We discuss turbulent dynamics and mixing of a variable-density flow subject to a uniformacceleration field. The flow resulting from initial misalignments of pressure and density gradients is investigated for small to large density ratios, with evidence that the smalldensity ratio flow is described by the Boussinesq approximation. A new shear-layer growth rate is reported. Spectra collapse when properly scaled for variable density.

Acceleration statistics of inertial particles in turbulent flow
Turbulent transport of material inclusions plays an important role in many natural and industrial situations. Being able to accurately model and predict the dynamics of dispersed particles transported by a turbulent carrier flow, remains a challenge. One critical and difficult point is to develop models which correctly describe the dynamics of particles over a wide range of sizes and density. O...
متن کاملThe Cessation of Continuous Turbulence as Precursor of the Very Stable Nocturnal Boundary Layer
The mechanism behind the collapse of turbulence in the evening as a precursor to the onset of the very stable boundary layer is investigated. To this end a cooled, pressure-driven flow is investigated by means of a local similarity model. Simulations reveal a temporary collapse of turbulence whenever the surface heat extraction, expressed in its nondimensional form h/L, exceeds a critical value...
متن کاملUnified explicit algebraic Reynolds stress model for compressible, heat-releasing and supercritical flows with large density variation
An explicit algebraic model (EARSM) for variable denstiy turbulent flow developed by Grigoriev et al. [Phys. Fluids (2015)] is revisited here. We apply it to a quasi one-dimensional nozzle flow, a wall-jet flow with combustion and large density variation and a supercritical flow of carbon dioxide with heat transfer and buoyancy. It is confirmed that the coupling between strong mean density grad...
متن کاملTransonic Turbulent Flow Simulation using Pressure-Based Method and Normalized Variable Diagram
A pressure-based implicit procedure to solve the Euler and Navier-Stokes equations on a nonorthogonal mesh with collocated finite volume formulation is described. The boundedness criteria for this procedure are determined from Normalized Variable diagram (NVD) scheme.The procedure incorporates the ε−k eddy-viscosity turbulence model. The algorithm is tested for inviscid and turbulent transonic ...
متن کاملOn the near-wall characteristics of acceleration in turbulence
The behaviour of fluid-particle acceleration in near-wall turbulent flows is investigated in numerically simulated turbulent channel flows at low to moderate Reynolds numbers, Reτ =180∼ 600. The acceleration is decomposed into pressure-gradient (irrotational) and viscous contributions (solenoidal acceleration) and the statistics of each component are analysed. In near-wall turbulent flows, the ...
