dc.description.abstract Global stability analysis of axisymmetric boundary layers RAMESHKUMAR BHORANIYA, VINOD NARAYANAN, Mechanical Engineer- ing, Indian Institute of Technology, Gandhinagar, India — Global stability analysis of the axisymmetric boundary layer flow explores the stability features of a nonpar- allel flow. Consider an incompressible flow past a cylinder, where flow direction is parallel to the axis of cylinder. The ensuing boundary layer is axisymmetric but non-similar. Due to the boundary layer growth, the velocity profile is two dimen- sional. This work aims to understand the nonparallel effects of an axisymmetric boundary layer using a biglobal stability analysis. The linearized biglobal stability equations are derived in polar cylindrical coordinates. The resulting stability equa- tions along with boundary conditions form an eigenvalue problem, which is solved using Chebyshev spectral collocation method. Arnoldi’s algorithm is used to com- pute selective eigenvalues and eigenfunctions. The results show that the nonparallel effects are considerable at very moderate Reynolds numbers. More detailed results will be presented at the time of conference en_US
