Abstract

In the present work, the effect of fluid’s elasticity was investigated on the HYDRODYNAMIC INSTABILITY of BLASIUS FLOW. To determine the CRITICAL REYNOLDS NUMBER as a function of the ELASTICITY NUMBER, a two-dimensional linear temporal stability analysis was invoked. The viscoelastic fluid is assumed to obey the Walters’ B fluid model for which base flow velocity profiles were fortunately available from literature. Neglecting terms nonlinear in the perturbation quantities, a Generalized Orr-Sommerfeld equation was obtained incorporating an elastic term. The eigenvalue problem so obtained was solved numerically using the Chebychev collocation-point method. Based on the results obtained in this work, fluid’s elasticity is predicted to have a destabilizing effect on the BLASIUS FLOW.
