Description
The aim of the present study is an experimental investigation of thermoconvective instabilities in a mixed convection phenomenon. The flow of fluid (water) in a horizontal rectangular duct uniformly heated from below is considered. According to the fluid velocity and heat flux supplied to the wall, several flow regimes occur. For moderate Reynolds numbers (300 < Re < 1200) a thermoconvective instability appears. It manifests itself through sporadic fluctuations of the fluid temperature. Amplitude of fluctuations and laminar durations are time varying. This paper concerns the description of this phenomenon and the characterisation of this intermittency
