Natural convection of suspension was studied experimentally using both Laser Induced Fluorescent (LIF) technique and Particle Tracking Velocimetry (PTV). Glass beads of 50 μm diameter were dispersed in a refractive index matching fluid of a tetralin and silicone oil mixture. A rectangular test section was filled with the suspension and was heated from a horizontal bottom, and two facing vertical walls were kept at the constant temperature. Argon ion laser light sheet was used for excitation light for the tracer particles dyed with fluorescence color. The images of the fluorescent particles were captured by a CCD camera through a sharp cut filter which separates emitted fluorescence from scattered excitation light. The flow velocity fields were analyzed quantitatively using PTV. The formation and breakdown of convection cells have been clarified.
