Numerical simulation of viscoelastic fluid flow past a cylinder on a streamfunction coordinate system
Steady two-dimensional flow of a viscoelastic fluid past a streamlined cylinder is numerically modeled using the von Mises coordinates. The governing equations for a second-order fluid flow past the cylinder are first transformed into a streamfunction coordinate system. Several approximation formulas for the vorticity on the surface of the cylinder are derived and employed in obtaining the solutions at various Reynolds and Weissenberg numbers for two specific cross-sections.
