This book was released on 2003-06-01 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research presents the results or a combined numerical and experimental study or heat transfer and pressure drop behavior in a compact heat exchanger (CHE) designed with drop-shaped pin tins. A numerical study using ANSYS was first conducted to select the optimum pin shape and configuration for the CHE. This was followed by an experimental study to validate the numerical model. The results indicate that the drop shaped pin tins yield a considerable improvement in heat transfer compared to circular pin tins tor the same pressure drop characteristics. This improvement is mainly due to the increased wetted surface area of the drop pins, and the delay in the flow separation as it passes the more streamlined drop shaped pin tins. The data and conclusions of this study can he used in heat exchanger design tor large heat flux cooling applications as in gas turbine blades, and high-power electronics.
Download or read book Numerical and Experimental Analysis of the Performance of Staggered Short Pin Fin Heat Exchangers written by Leonard J. Hamilton and published by . This book was released on 2003-06-01 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three dimensional finite element based numerical model was used to analyze the heat transfer characteristics of various staggered short pin-fin array heat exchangers. The simulation was validated against data from an experimental rig as well as historical data and then used to estimate the heat transfer coefficient and pressure drop for a wide range of Reynolds numbers for circular and airfoil-shaped pin fins. Circular pin configuration variations included changes in pin spacing, axial pitch and pin height ratio. Airfoil pin variations also included changes in length and aspect ratio. Correlations for Nusselt number and friction factor were developed. Using established performance metrics optimum configurations for both pin shapes were determined. The optimum airfoil pin array was shown to match the heat transfer rates obtained by the optimum circular pin configuration while incurring less than one third the specific fluid friction power loss. The results from this study would be of direct value in the design of a shroud enclosed heat exchanger concept being proposed for turbine blade cooling, or for cooling of high power electronic components, or in other high heat flux dissipation applications requiring a low- profile, high area-density based micro-heat exchanger design.

Book excerpt: A detailed experimental study has been carried out on the heat transfer and pressure drop characteristics of a compact heat exchanger with pin fins, A modular wind- tunnel with a rectangular cross-section duct-flow area was constructed that would accommodate the heat exchanger test section with varying pin designs. The flow in the tunnel was achieved through a suction-type blower, and a leading entrance length section was added to achieve predictable flow conditions into the heat exchanger test section. The rig was comprehensively instrumented to provide all desired thermal and flow data. The results from this study provide useful empirical data to validate ongoing numerical studies of such heat exchanger designs.
