This book was released on 2010-04-28 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: After Surrey in 1994, Grenoble in 1996, Cambridge in 1999, Enschede in 2001, Munich in 2003 and Poiters in 2005, the 7th Workshop, DLES7, will be held in Trieste, again under the auspices of ERCOFTAC. Following the spirit of the series, the goal of this latest workshop is to establish a state-of-the-art of DNS and LES techniques for the computation and modeling of transitional/turbulent flows covering a broad scope of topics such as aerodynamics, acoustics, combustion, multiphase flows, environment, geophysics and bio-medical applications. This gathering of specialists in the field should once again be a unique opportunity for discussions about the more recent advances in the prediction, understanding and control of turbulent flows in academic or industrial situations.

Book excerpt: It is our pleasure to present these proceedings from the United Engineering Foundation Conference on The Aerodynamics of Heavy Vehicles: Trucks, Buses and Trains held December 2-6, 2002, in Monterey, California. This Department of Energy, United Engineering Foundation, and industry sponsored conference brought together 90 leading engineering researchers from around the world to discuss the aerodynamic drag of heavy vehicles. Participants from national labs, academia, and industry, including truck manufacturers, discussed how computer simulation and experimental techniques could be used to design more fuel efficient trucks, buses, and trains. Conference topics included comparison of computational fluid dynamics calculations using both steady and unsteady Reynolds-averaged Navier-Stokes, large-eddy simulation, and hybrid turbulence models and experimental data obtained from the Department of Energy sponsored and other wind tunnel experiments. Advanced experimental techniques including three-dimensional particle image velocimetry were presented, along with their use in evaluating drag reduction devices. We would like to thank the UEF conference organizers for their dedication and quick response to sudden deadlines.

Book Synopsis An Experimental Study of Surface-mounted Bluff Bodies Immersed in Thick Turbulent Boundary Layers by : Helen Afi Amorin
Download or read book An Experimental Study of Surface-mounted Bluff Bodies Immersed in Thick Turbulent Boundary Layers written by Helen Afi Amorin and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a study of an experimental investigation of the effects of spanwise aspect ratio on the turbulent properties of separation bubbles over a surface-mounted bluff body. In this study, the streamwise aspect ratio was kept constant at [...]/h = 2.36 and the spanwise aspect ratio was varied from 1 to 20. The body was immersed in a turbulent boundary layer whose thickness is equivalent to 4.8 times the body height. The Reynolds number, based on the body height and freestream velocity, was 12500. A time-resolved particle image velocimetry (TR-PIV) method was used to measure the velocity field within the separation bubble to quantify the influence of varying spanwise aspect ratio on the mean flow and turbulent characteristics. Two distinct separation bubbles developed on top and downstream of the bluff bodies. The results showed that the reattachment lengths of both separation bubbles are influenced by the aspect ratio; they increased monotonically as aspect ratio increased from [...]/h = 1 to 8, and reach asymptotic values and do not vary significantly with aspect ratio larger than 8. The effects of aspect ratios on the mean velocities, Reynolds stresses, triple velocity correlations and turbulence production are also examined over the bluff body. Galilean decomposition, quadrant decomposition, joint probability density function (JPDF), two-point auto-correlation function and proper orthogonal decomposition (POD) are also used to investigate the impact of spanwise aspect ratio on the structures present in the flow field.

Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of the world renowned ERCOFTAC (International Symposium on Engineering Turbulence Modelling and Measurements).The proceedings include papers dealing with the following areas of turbulence:·Eddy-viscosity and second-order RANS models ·Direct and large-eddy simulations and deductions for conventional modelling ·Measurement and visualization techniques, experimental studies ·Turbulence control ·Transition and effects of curvature, rotation and buoyancy on turbulence ·Aero-acoustics ·Heat and mass transfer and chemically reacting flows ·Compressible flows, shock phenomena ·Two-phase flows ·Applications in aerospace engineering, turbomachinery and reciprocating engines, industrial aerodynamics and wind engineering, and selected chemical engineering problems Turbulence remains one of the key issues in tackling engineering flow problems. These problems are solved more and more by CFD analysis, the reliability of which depends strongly on the performance of the turbulence models employed. Successful simulation of turbulence requires the understanding of the complex physical phenomena involved and suitable models for describing the turbulent momentum, heat and mass transfer. For the understanding of turbulence phenomena, experiments are indispensable, but they are equally important for providing data for the development and testing of turbulence models and hence for CFD software validation. As in other fields of Science, in the rapidly developing discipline of turbulence, swift progress can be achieved only by keeping up to date with recent advances all over the world and by exchanging ideas with colleagues active in related fields.
