β¦ Synopsis
The solution for slow incompressible flow past a circular cylinder involves terms in powers of 1 / log e, times powers of 1 / log e, etc., where c is the Reynolds number. Previously we showed how to determine the sum of all terms in powers of 1/log e. Now we show how to go beyond all those terms to find the sum of all terms containing e times a power of 1/log e. The first sum gives the drag coefficient and represents a symmetric flow in the Stokes region near the cylinder. The second term reveals the asymmetry of the flow near the body. This problem is studied using a hybrid method which combines numerical computation and asymptotic analysis.

Several issues related to applications of the dynamic subgrid-scale (SGS) model in large-eddy simulation (LES) at low Reynolds number are investigated. A modified formulation of the dynamic model is constructed and its perfoxmance in low-Reynolds-number LES of channel flow is assessed through a comp
A numerical method is constructed for two-dimensional Navier-Stokes ows in a circular domain. Adaptive computational grids are employed to resolve the boundary layer and the boundary vorticity values are obtained in high order of accuracy. Numerical results show a quite good agreement with the asymp
