Numerical laminar and turbulent fluid flow and heat transfer predictions in tube banks
TL;DR: In this article, the steady state Reynolds-averaged Navier-Stokes equations are discretised by means of a cell-centred finite-volume algorithm, which is suitable as a design tool for tube banks in heat exchangers.

Numerical modelling of three-dimensional fly-ash flow in power utility boilers
TL;DR: In this paper, a two-fluid Eulerian model in combination with a particle-wall collision model and generalized Eulerians boundary conditions for the particulate phase is employed to predict complex three-dimensional fly-ash flows which often cause severe erosion to boiler tubes located in power utility boilers.

Incompressible Viscous Flow
Clive A. J. Fletcher
- 01 Jan 1991
TL;DR: In this chapter no assumption is made about the relative magnitude of the velocity components, consequently, reduced forms of the Navier-Stokes equations (Chap. 16) are not available and it is assumed that the flow is incompressible.

Gas particle industrial flow simulation using ranstad
TL;DR: In this paper, a turbulent gas particle finite-volume flow simulation of a representative coal classifier is presented, where the simulation indicates that small (≈ 30 µm) coal particles pass through the classifier to the furnace but that large particles are captured and remilled.

An auxiliary potential velocity method for incompressible viscous flow
TL;DR: In this article, a novel auxiliary potential velocity scheme for incompressible flows is presented, which is characterized by high accuracy, robustness and simple implementation, and applied it to several benchmark problems (internal duct flow, flow over a backward facing step).

TL;DR: In this article, a general, numerical, marching procedure is presented for the calculation of the transport processes in three-dimensional flows characterised by the presence of one coordinate in which physical influences are exerted in only one direction.

Implicit Finite-Difference Simulations of Three-Dimensional Compressible Flow
TL;DR: In this article, an implicit finite-difference procedure for unsteady 3D flow capable of handling arbitrary geometry through the use of general coordinate transformations is described, where viscous effects are optionally incorporated with a "thin-layer" approximation of the Navier-Stokes equations.

A Pseudospectral method for solution of the three-dimensional incompressible Navier-Stokes equations
TL;DR: In this article, a new Chebyshev pseudospectral technique based on the projection method that was previously applied by the authors to the solution of two-dimensional incompressible Navier-Stokes equations in primitive variables for nonperiodic boundary conditions is extended to solve the three-dimensional Navier Stokes equations.
