This book was released on 1966 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In chemical industry as well as in nature, one encounters numerous situations in which there is intimate contact between a finely sub-divided solid or a liquid-dispersed phase and a continuous fluid phase. This phenomenon occurs primarily in moving liquids or gaseous media and is being increasingly encountered in practical engineering applications, such as solids-gas contacting operations, spray processes, air pollution control and the design or solids-burning rocket engines.

Download or read book Modeling of Gas to Particle Mass Transfer in Turbulent Flows written by Sean C. Garrick and published by Springer. This book was released on 2017-06-29 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Brief focuses on the dispersion of high-porosity particles, their entrainment into the vapor-laden stream, and the condensation of vapor onto the particles. The authors begin with a simple/static problem, focusing on transport within the particle. They go on to consider the high-resolution simulation of particles in a turbulent flow and the time-dependent evolution of the fluid-particle fields. Finally, they examine the more computationally-affordable large-eddy simulation of gas-to-particle mass-transfer. The book ends with a summary and challenges as well as directions for the area.
Download or read book Turbulent Drag Reduction by Surfactant Additives written by Feng-Chen Li and published by John Wiley & Sons. This book was released on 2012-01-10 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbulent drag reduction by additives has long been a hot research topic. This phenomenon is inherently associated with multifold expertise. Solutions of drag-reducing additives are usually viscoelastic fluids having complicated rheological properties. Exploring the characteristics of drag-reduced turbulent flows calls for uniquely designed experimental and numerical simulation techniques and elaborate theoretical considerations. Pertinently understanding the turbulent drag reduction mechanism necessities mastering the fundamentals of turbulence and establishing a proper relationship between turbulence and the rheological properties induced by additives. Promoting the applications of the drag reduction phenomenon requires the knowledge from different fields such as chemical engineering, mechanical engineering, municipal engineering, and so on. This book gives a thorough elucidation of the turbulence characteristics and rheological behaviors, theories, special techniques and application issues for drag-reducing flows by surfactant additives based on the state-of-the-art of scientific research results through the latest experimental studies, numerical simulations and theoretical analyses. Covers turbulent drag reduction, heat transfer reduction, complex rheology and the real-world applications of drag reduction Introduces advanced testing techniques, such as PIV, LDA, and their applications in current experiments, illustrated with multiple diagrams and equations Real-world examples of the topic’s increasingly important industrial applications enable readers to implement cost- and energy-saving measures Explains the tools before presenting the research results, to give readers coverage of the subject from both theoretical and experimental viewpoints Consolidates interdisciplinary information on turbulent drag reduction by additives Turbulent Drag Reduction by Surfactant Additives is geared for researchers, graduate students, and engineers in the fields of Fluid Mechanics, Mechanical Engineering, Turbulence, Chemical Engineering, Municipal Engineering. Researchers and practitioners involved in the fields of Flow Control, Chemistry, Computational Fluid Dynamics, Experimental Fluid Dynamics, and Rheology will also find this book to be a much-needed reference on the topic.
Download or read book Drag Coefficients for Droplets and Solid Spheres in Clouds Accelerating in Airstreams written by Robert D. Ingebo and published by . This book was released on 1956 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clouds of liquid and solid spheres accelerating in airstreams were studied over a range of airstream pressure, temperature, and velocity conditions. Diameter and velocity data for individual droplets and solid spheres in the clouds were obtained with a high-speed camera developed at the NACA Lewis laboratory. From these data, ltiear accelerations of spheres (20 to 120 microns in diam.) were determnied, and instantaneous drag coefficients for unsteady momentum transfer were calculated. When acceleration rates were low, the unsteady-state drag coefficients were in agreement with steady-state values from previous investigations. From this expression for drag coefficient, an equation relattig distance and time was derived for calculating trajectories of solid spheres. In the case of droplets, a graphical method was used to relate droplet diameter to distance when evaporation rates were high. When evaporation rates were low, solid-sphere trajectory equations were found applicable.
Download or read book Sphere Drag in a Low Density Supersonic Flow written by Jerome Aroesty and published by . This book was released on 1962 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sphere drag coefficients were measured in the Berkeley Low Density Wind Tunnel at Mach equals 2, 4, and 6, and free stream Reynolds numbers between 10 and 10,000 for both insulated and cold wall conditions. The measurements indicate that sphere drag in this regime is strongly dependent on the Reynolds number behind a normal shock wave, and only weakly dependent on Mach number. In addition, it was found that a decrease in wall temperature/stagnation temperature (T sub w/T sub o) from 1 to 0.26 was accompanied by a 5 - 10% decrease in the drag coefficient. A precision microbalance was used to obtain data for insulated spheres, and a moving model technique was used to obtain data for small spheres falling freely through a wind tunnel jet. These latter tests were performed using both cold and insulated models. The results on insulated spheres at M equal 2 and 4 were in good agreement with the measurements of other investigators. The results of the cold wall tests indicate that for Mach numbers greater than 5 in air, sphere drag coefficients are a function only of T sub w/T sub o and the post normal shock Reynolds number.

Download or read book Drag Coefficients for Spheres in Free Molecular Flow in O at Satellite Velocities written by John W. Boring and published by . This book was released on 1973 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The drag coefficients for the Echo 1 and Explorer 24 spherical surfaces in an O environment were experimentally determined over an energy range of 4 to 200 eV. The experiment was performed by generating a beam of atomic oxygen ions of the proper energy, neutralizing a portion of the beam, and then allowing only the neutral O particles to strike a very sensitive torsion balance. The momentum transferred to the surface was determined from the deflection of the torsion balance. At the lower energies, the more intense ion beam had to be used instead of the neutral beam. The drag coefficients are found to be slightly greater than 2 at energies corresponding to satellite velocities.
