Abstract

Discussed in this work is the stability of the two dimensional flow of a viscous incompressible fluid past an inclined elliptic cylinder. A linear stability analysis has been carried out to estimate the critical Reynolds number, /?C5 &t which the flow becomes unstable to asymmetric disturbances. The minimum RC has been estimated to lie in the range 35 < RC < 40 and to occur for an inclination in the interval 40° < #<, < 50°. Also, for the case of a stationary circular cylinder RC was estimated to be between 100 < RC < 110. 1 Introduction This paper deals with the stability of the two dimensional flow
