An Incompressible Inner Flow Analysis by Absolute Differential form of Navier-Stokes Equation on a Curvilinear Coordinate System
In this paper, an incompressible inner flow analysis scheme which is based on the absolute differential form for the conventional equations of the incompressible viscous flow is presented. The physical components of the contravariant vector are taken as velocity variables and the equations are discretized on a staggered mesh system. Consequently, the calculation is performed stably and the good agreement with the experimental results has been shown in the prediction of the natural convection in the horizontal eccentric cylindrical annuli.
