This paper presents an experimental study on the flow structures in turbulent Rayleigh-Benard convection with surfactant solutions. The shadowgraph visualization was used to obtain the plumes and the velocity field was measured using particle image velocimetry. The results show that the size of plumes in surfactant solution case is larger than that in Newtonian fluid case and it needs more time for surfactant solution case to start convection. The large-scale circulation fails to form in surfactant solution case and the convection velocity is smaller. A decrease of the measured Nusselt number is observed in surfactant solution case. The phenomena are caused by the shear-shinning and elastic characteristics of surfactant solution.

Curved Pipe

Horizontal curved pipe which are widely used in the engineering project and less researched were selected to study in the high concentration of fluidized transportation. Compressed air was used as the transmission power and gypsum powder as the transport medium. And then, the flow characteristics in horizontal curved pipeline of dense phase pneumatic conveying gypsum powder were achieved. The experimental results showed that the geometry parameters such as angle of the bend, radius of curvature and operating parameters i.e. conveying pressure, gas velocity, solid velocity etc have a dominant effect on the gas solid flow process.

Straight Pipe

A surfactant is well known as an additive that brings about drag-reduction in straight (non-swirling) pipe flow. However in industrial applications of the drag-reducing effect, many flow fields exist including the straight pipe flow. The purpose of this study is to investigate the flow characteristics of surfactant solution swirling pipe flow. The drag reducing effect is estimated from the measurement wall pressure loss and the velocity profiles on various pipe sections are measured by 2 dimensional LDV. Since the surfactant solution has viscoelasticity, interesting flow characteristics are shown. The decay of swirl, the vortex type and the turbulence intensity are discussed, compared with the water swirling flow. The oscillating of vortex core is also investigated.
