✦ Synopsis

The entry flow of viscoelastic second-order fluid between two parallel plates is discussed. The governing equations of vorticity and the streamfunction are expanded with respect to a small parameter that characterizes the elasticity of the fluid by means of the standard perturbation method. By using the differential quadrature method with only a few grid points, high-accurate numerical solutions are obtained. The numerical results show a lot of the features of a viscoelastic second-order fluid.
