General Three-Dimensional Viscous Primary/Secondary Flow Analysis
TL;DR: In this paper, generalized primary/secondary flow equations are derived as an approximation to the Navier-Stokes equations for three-dimensional viscous flows with a dominant flow direction, and a sequentially decoupled implicit algorithm has been developed that exploits the form of the primary and secondary flow equations to obtain decouple subsets of equations through choices for dependent variables, the sequence of equations, and the linearization scheme.

Numerical Analysis of Heated Channel Flows by a Space-Marching Finite Volume Technique
TL;DR: In this paper, a parabolized Navier-Stokes equation is used for cooling properties of real fluids in channels, based on a finite volume approach, which uses a modified Roe's approximate Riemann solver for a fluid governed by a generic equation of state.

Three-dimensional turbulent near-wall flows in streamwise corners: Current state and questions
TL;DR: In this article, the structure, properties and main regularities of 3D near-wall turbulent flows in a wide range of variable conditions and basic parameters are discussed. And the main factors on the structure of the flow in streamwise corners are analyzed, including the effectiveness of flow control by streamwise vortices in the junction regions of aerodynamic surfaces.

W.P. Jones,Brian Launder +1 more
TL;DR: In this article, the local turbulent viscosity is determined from the solution of transport equations for the turbulence kinetic energy and the energy dissipation rate, and the predicted hydrodynamic and heat-transfer development of the boundary layers is in close agreement with the measured behaviour.

TL;DR: In this article, an algebraic turbulence model for two-and three-dimensional separated flows is specified that avoids the necessity for finding the edge of the boundary layer, and compared with experiment for an incident shock on a flat plate, separated flow over a compression corner, and transonic flow over an airfoil.
