An experimental investigation of turbulent non-Newtonian fluid flow and solids transport in horizontal concentric annulus is the main subject matter of this research. In the first part of this research, turbulent flow of water and non-Newtonian fluids in horizontal annuli were investigated by using the state of the art Particle Image Velocimetry technique. Different aspects of turbulent flow such as frictional pressure losses, velocity profiles, shear stress distributions and near wall turbulent intensities were analysed.
In the second part of the study, solid transport experiments were conducted using turbulent flow of water and polymer fluids. Various flow patterns of particle transport (i.e. dunes or separated sand clusters) were identified. Critical velocity and pressure loss required for initiating particle movement in different transport mode (i.e. rolling or saltation) were determined. Effects of fluid rheology (water vs. non-Newtonian fluid) and cuttings size (fine vs. coarse particles) on the critical conditions were investigated. -
