Download or read book Fin Shape Thermal Optimization Using Bejan s Constuctal Theory written by Giulio Lorenzini and published by Morgan & Claypool Publishers. This book was released on 2011-01-02 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book contains research results obtained by applying Bejan's Constructal Theory to the study and therefore the optimization of fins, focusing on T-shaped and Y-shaped ones. Heat transfer from finned surfaces is an example of combined heat transfer natural or forced convection on the external parts of the fin, and conducting along the fin. Fin's heat exchange is rather complex, because of variation of both temperature along the fin and convective heat transfer coefficient. Furthermore possible presence of more fins invested by the same fluid flow has to be considered. Classical fin theory tried to reduce the coupled heat transfer problem to a one-dimensional problem by defining an average temperature of the fin and writing equations using this parameter. However, it was shown that this approach cannot be used because of the effects of two-dimensional heat transfer, especially in the presence of short fins. CFD codes offer the possibility to consider bi-dimensional (and more generally, three-dimensional) effects and then a more real approach to the physic phenomena of finned surface's heat exchange. A commercial CFD code was used to analyse the case of heat exchange in presence of T-shaped fins, following an approach suggested by Bejan's Constructal Theory. The comparative results showed a significant agreement with previous research taken as a reference, and this result allows for the application of this approach to a wider range of systems. T-shaped optimized fin geometry is the starting point for further research. Starting from the optimal results (T-shape optimized fins), we show the trend of the assessment parameter (the dimensionless conductance) in function of the angle α between the two horizontal arms of the fin. A value for α, 90°

Download or read book Three Dimensional Attached Viscous Flow written by Ernst Heinrich Hirschel and published by Springer Science & Business Media. This book was released on 2013-10-29 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viscous flow is treated usually in the frame of boundary-layer theory and as two-dimensional flow. Books on boundary layers give at most the describing equations for three-dimensional boundary layers, and solutions often only for some special cases. This book provides basic principles and theoretical foundations regarding three-dimensional attached viscous flow. Emphasis is put on general three-dimensional attached viscous flows and not on three-dimensional boundary layers. This wider scope is necessary in view of the theoretical and practical problems to be mastered in practice. The topics are weak, strong, and global interaction, the locality principle, properties of three-dimensional viscous flow, thermal surface effects, characteristic properties, wall compatibility conditions, connections between inviscid and viscous flow, flow topology, quasi-one- and two-dimensional flows, laminar-turbulent transition and turbulence. Though the primary flight speed range is that of civil air transport vehicles, flows past other flying vehicles up to hypersonic speeds are also considered. Emphasis is put on general three-dimensional attached viscous flows and not on three-dimensional boundary layers, as this wider scope is necessary in view of the theoretical and practical problems that have to be overcome in practice. The specific topics covered include weak, strong, and global interaction; the locality principle; properties of three-dimensional viscous flows; thermal surface effects; characteristic properties; wall compatibility conditions; connections between inviscid and viscous flows; flow topology; quasi-one- and two-dimensional flows; laminar-turbulent transition; and turbulence. Detailed discussions of examples illustrate these topics and the relevant phenomena encountered in three-dimensional viscous flows. The full governing equations, reference-temperature relations for qualitative considerations and estimations of flow properties, and coordinates for fuselages and wings are also provided. Sample problems with solutions allow readers to test their understanding.
Download or read book Flow Structure Characterization and Performance Evaluation of Pin Fins Produced Using Cold Spray written by Philippe Dupuis and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy efficiency has become a growing concern in a world driven by a fossil fuel economy. Recuperated micro-gas-turbine systems offer the possibility of high efficiency power generation for low output power systems. To this end, increasing the performance while decreasing the cost, the weight and the volume of heat exchangers such as recuperators has become a critical research focus. Recent work done by Brayton Energy Canada (BEC) has renewed interest in Wire Mesh Heat Exchangers (WMHE) by introducing a new production method that uses cells of stacked wire mesh sheets that have a thick external shell deposited by cold spray. Fins are then machined in this external shell, creating a heat exchanger. Net shaped pin fins were successfully deposited using Cold Gas Dynamic Spraying (CGDS or simply cold spray) as an additive manufacturing technique to replace the plate fin arrays currently used. This new development is envisioned to save costs while providing higher heat transfer efficiency than traditional fin arrays. Increasing the performance of such fin arrays would yield higher heat exchanger efficiencies and increase the total efficiency of the gas turbine system. The present thesis provides a description of the research performed, as well as the results thereof, with regards to the performance of pin fin arrays produced using cold spray. A review of the relevant literature is performed to establish the motivation of this study and to describe the relevant work that has been performed by other authors in this respect. The research objectives are to evaluate the thermal and hydrodynamic performance of these fin arrays and relate those to the flow structures arising from fluid motion between these extended surfaces. Furthermore, the proposed approach and the experimental equipment that will be used are described in this work. The research objectives were successfully met, with the results obtained from this work presented in the form of peer-reviewed publications.
