Book excerpt: Turbulence Phenomena provides an introduction to the eddy transfer of momentum, mass, and heat, specifically at interfaces. The approach of the discussion of the subject matter is based on the eddy mixing length concept of Prandtl. Chapter 1 begins with a discussion on basic concepts regarding liquid flow such as viscosity, turbulent flows, and velocities. As concepts and theories are established, the book then discusses the eddy transfer in fluids, specifically eddy transfer of mass and heat within fluids and eddy transfer near solid surfaces. The concept of eddies in different surfaces is discussed in length all throughout numerous chapters. These different surfaces include clean gas-liquid surfaces, clean liquid-liquid interfaces, and film-covered surfaces. The last few chapters focus on the more detailed discussion on turbulence, such as the concept of spontaneous interfacial turbulence and emulsification and turbulent dispersion and coalescence. The book will be of great use to undergraduate students of chemical engineering, physics, and chemistry.

This book was released on 2013 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book gives a brief but thorough introduction to the fascinating subject of non-Newtonian fluids, their behavior and mechanical properties. After a brief introduction of what characterizes non-Newtonian fluids in Chapter 1 some phenomena characteristic of non-Newtonian fluids are presented in Chapter 2. The basic equations in fluid mechanics are discussed in Chapter 3. Deformation kinematics, the kinematics of shear flows, viscometric flows, and extensional flows are the topics in Chapter 4. Material functions characterizing the behavior of fluids in special flows are defined in Chapter 5. Generalized Newtonian fluids are the most common types of non-Newtonian fluids and are the subject in Chapter 6. Some linearly viscoelastic fluid models are presented in Chapter 7. In Chapter 8 the concept of tensors is utilized and advanced fluid models are introduced. The book is concluded with a variety of 26 problems. Solutions to the problems are ready for instructors

Available in PDF, EPUB and Kindle. Book excerpt: Blood is a complex fluid and has been established to behave as a shear thinning non-Newtonian fluid when exposed to low shear rates (200s-1). Many hemodynamic investigations use a Newtonian fluid to represent blood when the flow field of study has relatively high shear rates. Shear thinning fluids have been shown to exhibit differences in transition to turbulence compared to that of Newtonian fluids. Incorrect assumption of the transition point in a simulation could result in erroneous prediction of hemodynamic forces. The goal of the present study was to compare velocity profiles near transition to turbulence of whole blood and standard blood analogs in a straight rigid pipe and an S-shaped pipe under a range of steady flow conditions. Reynolds number for blood was defined based on the viscosity at a shear rate of 400s-1. The rheometer was calibrated at shear rates of interest using Newtonian viscosity standards. Doppler ultrasound was used to measure velocity profiles of whole porcine blood and a Newtonian fluid in an in vitro experiment at 18 different Reynolds numbers ranging from 750 to 3500 (straight pipe) and 21 different Reynolds numbers ranging from 500 to 2800 (S-shaped pipe). Three samples of each fluid were examined and fluid rheology was measured before and after each experiment. Straight pipe results show parabolic velocity profiles for both whole blood and the Newtonian fluid at Reynolds numbers less than 2100 (based on high shear rate viscosity). The Newtonian fluid had blunt velocity profiles with large velocity fluctuations (root mean square as high as 18%) starting at Reynolds numbers ~2100-2300 which indicated transition to turbulence. In contrast, whole blood did not transition to turbulence until a Reynolds number of ~2500-2700. This delay was consistent for all three samples. For Reynolds numbers larger than 2100, the delay in transition resulted in differences in velocity profiles between the two fluids as high as 20%. A Newtonian assumption for blood at flow conditions near transition can lead to large errors in velocity prediction for steady flow in a straight pipe. For the S-shaped pipe geometry, the RMS velocity results show that the minimum Re where transition initiated for whole blood (~1000-1200) is slightly larger (10%) than that observed for a Newtonian fluid (~900-1000) under steady flow conditions. Repeated measurements show these results to be consistent for three different samples. These results show large differences in the magnitude of mean and fluctuation velocity between whole blood and a Newtonian fluid for Re>1000. Further research is necessary to understand this relation in more complex geometries and under pulsatile flow conditions.
