Abstract

A consideration of the mechanisms underlying disturbance introduction in a natural convection boundary layer has been carried out. The nature and magnitude of the introduced disturbance are interpreted from measurements of the amplified disturbance downstream. The dependence of the introduced disturbance on input parameters, like amplitude, position and frequency, is studied in detail. The study answers several fundamental questions concerning the artificial introduction of disturbances in a natural convection flow and relates the results obtained to naturally-occurring disturbances. It also brings out several interesting points on disturbance behavior in natural convection flows.
