Download or read book A Numerical Study of Pulse combustor Jet Impingement Heat Transfer written by Wichit Liewkongsataporn and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A pulsating jet generated by a pulse combustor has been experimentally demonstrated as a technique for impingement heat transfer enhancement relative to a steady jet. The enhancement factor was as high as 2.5. Despite such potential, further studies of this technique have been limited, let alone industrial applications. The ultimate goal of the Pulsed Air Drying project at the Institute of Paper Science and Technology is to develop this technique to commercialization for industrial applications such as paper drying. The main objective of the research in this dissertation is to provide a fundamental basis for the development of the technology. Using CFD simulations, the research studied the characteristics of pulsating single-slot-nozzle jet impingement flows and heat transfer on stationary and moving surfaces. In addition, in order to understand basic flow characteristics of pulse-combustor jets, a simplified model of Helmholtz pulse combustors was developed. The model was used to recommend a strategy to generate a pulsating jet having large amplitude of velocity oscillation. And based on this model, pulsating jets in the simulations were characterized as those at the tailpipe exit of a pulse combustor. The impingement conditions were similar to those in conventional impingement hoods for paper drying. Parameter studies included the effects of jet velocity oscillation amplitude, pulsation frequency, mean jet velocity, tailpipe width, and impingement surface velocity. Simulation results showed that the amplitude of jet velocity oscillation was the most important parameter for heat transfer enhancement, in which two mechanisms were identified: high impinging jet velocity during the positive cycle and strong re-circulating flows in the impingement zone during the negative cycle of jet velocity oscillation. As for the improvement by the pulsating jets relative to steady jets, the maximum heat transfer enhancement and energy saving factors were 1.8 and 3.0, respectively, which were very encouraging for further development of the technology.

Available in PDF, EPUB and Kindle. Book excerpt: Flame jet impingement heat transfer is a critical process in many industries.It is a very old and effective technique used for a wide spectrum of applications, ranging from welding and glass forming to domestic LPG burner. Complete understanding of physical and chemical processes involved are required for proper burner design, improving efficiency and reducing combustion generated pollutants. The present work is based on the computer simulation of the most basic type of flame impingement heat transfer, i.e., impingement on a plane surface.The present study aims at investigating various operating conditions for a flame jet impingement and the effect of variation of these parameters on the flame structure and the heat transfer characteristics. First the case of single and twin isothermal jets impinging on a plane surface is studied. The case of flame jet impingement normal to the target plate was studied next.The effect of various operating conditions was evaluated. The effect of variation of exit velocity profile, equivalence ratio, Re, and nozzle to plate separation distance were investigated. Lastly, the case of flame jet impingement on an inclined flat plate is studied.

Download or read book Direct and Large Eddy Simulation XII written by Manuel García-Villalba and published by Springer Nature. This book was released on 2020-05-09 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the proceedings of the 12th instalment in the bi-annual Workshop series on Direct and Large Eddy Simulation (DLES), which began in 1994 and focuses on modern techniques used to simulate turbulent flows based on the partial or full resolution of the instantaneous turbulent flow structure. With the rapidly expanding capacities of modern computers, this approach has attracted more and more interest over the years and will undoubtedly be further enhanced and applied in the future. Hybrid modelling techniques based on a combination of LES and RANS approaches also fall into this category and are covered as well. The goal of the Workshop was to share the state of the art in DNS, LES and related techniques for the computation and modelling of turbulent and transitional flows. The respective papers highlight the latest advances in the prediction, understanding and control of turbulent flows in academic and industrial applications.
