A stable and accurate convective modelling procedure based on quadratic upstream interpolation
TL;DR: In this paper, a convective modeling procedure is presented which avoids the stability problems of central differencing while remaining free of the inaccuracies of numerical diffusion associated with upstream differencings.

Predictions of Channel and Boundary-Layer Flows with a Low-Reynolds-Number Turbulence Model
TL;DR: In this paper, the Taylor series expansion technique was used to systematically investigate the proper behavior of the turbulent shear stress and the kinetic energy and its rate of dissipation near a solid wall.

A method for including arbitrary external boundaries in the MAC incompressible fluid computing technique
TL;DR: In this article, a method is proposed which treats the fluid boundary at an arbitrarily curved wall or obstacle as if it were a free surface, to which a pressure is applied such that the particles at the boundary line move tangent to it.
