Abstract

This paper presents the results of an experimental investigation of the behaviour of artificial disturbances produced by an oscillating ribbon in the free convection boundary layer over a vertical uniform flux plate. The boundary layer was observed using a Mach Zehnder interferometer. The observations resulted in the approximate location of a neutral curve which is in good agreement with calculations from the linear stability theory.
