Title: Nonclassical polynomials based spectral Galerkin formulation in a swirling flow stability problem
Published In: Proceedings of APLIMAT, Bratislava, Feb. 5-7, 2013
Description: The properties of the spatial instability waves supported by the Batchelor vortex are investigated here using a polynomials based Galerkin technique. The polynomials basis used in the approximation is proposed in order to optimally satisfy the boundary conditions of the two-point boundary value problem governing the linear stability of the flow for the non-axisymmetric modes case. It is shown that the formulation provides fair accuracy and the numerical results are in good agreement with existing ones. The physical parameters influence on the stability domain of the swirling flow is pointed out.
