A numerical study on the generation mechanism of turbulence-driven secondary flow in a square duct

Journal Article Myong, Hyon Kook - Journal of Fluids Engineering; (United States)

The generation mechanism of turbulence-driven secondary flows in a square duct is numerically investigated in the present study by using an anisotropic low-Reynolds-number [kappa]-[epsilon] turbulence model. Special attention is directed to the distributions of turbulence quantities, which are responsible for the secondary flow generation, such as the anisotropy of normal Reynolds stresses and the secondary Reynolds shear stress acting on the cross-sectional plane. The vorticity transport process is also discussed in detail, based on the numerical evaluation of the individual terms which appear in the streamwise vorticity transport equation.

Direct numerical simulation of turbulent flow in a rotating square duct

Journal Article Dai, Yi-Jun ; Huang, Wei-Xi ; Xu, Chun-Xiao ; ... - Physics of Fluids (1994)

A fully developed turbulent flow in a rotating straight square duct is simulated by direct numerical simulations at Re{sub τ} = 300 and 0 ≤ Ro{sub τ} ≤ 40. The rotating axis is parallel to two opposite walls of the duct and normal to the main flow. Variations of the turbulence statistics with the rotation rate are presented, and a comparison with the rotating turbulent channel flow is discussed. Rich secondary flow patterns in the cross section are observed by varying the rotation rate. The appearance of a pair of additional vortices above the pressure wall is carefully examined, andmore »« less

Heat and mass transfer analysis of developing turbulent flow in a square duct

Journal Article Sugiyama, Hitoshi ; Akiyama, Mitsunobu - Heat Transfer - Japanese Research; (United States)

A numerical analysis has been performed on three-dimensional developing turbulent flow in a square duct using a modified Reynolds stress model and a transport equation model for the turbulent flux. Special attention was paid to the relation between the model constants and the Reynolds stress distribution and the developing process of the secondary flow of the second kind. Moreover, using a turbulent heat flux model, the mean Nusselt number was precisely predicted.
Computation of laminar and turbulent flow in 90-degree square-duct and pipe bends using the Navier-Stokes equations. Final report 1 Mar 81-28 Feb 82

Technical Report Briley, W R ; Buggeln, R C ; McDonald, H

Three-dimensional laminar and turbulent flow within 90-degree bends of strong curvature and both circular and square cross section are studied by numerical solution of the compressible Reynolds-averaged Navier-Stokes equations. The governing equations are expressed in a body-fitted orthogonal coordinate system and then solved using a consistently-split linearized block implicit (LBI) algorithm. The turbulence model and computational mesh provides for resolution of the viscous sublayer and employs an isotropic eddy viscosity based on solution of the turbulence kinetic energy equation and a specified length scale. Six different flow cases are considered , and the developing flow structure and its dependence onmore »« less
