Abstract
Hydrodynamic instabilities are present in many problems related to fluid mechanics. In aerospace engineering, the relevant applications are associated with air breathing propulsion engines such as turbojets, ramjets and scramjets, working in subsonic or supersonic state. For a viscous case of a jet flow profile, this work make a spacial instability analysis to find the critical Reynolds number for various azimuthal orders disturbances using the well know shooting method and the matrix forming method.
