This book was released on 1990 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This contribution deals with an experimental aero-thermal investigation around a highly loaded transonic turbine nozzle guide vane mounted in a linear cascade arrangement. The measurements were performed in the von Karman Institute short duration Isentropic Light Piston Compression Tube facility allowing a correct simulation of Mach and Reynolds numbers as well as of the gas to wall temperature ratio compared to the values currently observed in modern aero engines. The experimental program consisted of flow periodicity checks by means of wall static pressure measurements and Schlieren flow visualizations, blade velocity distribution measurements by means of static pressure tappings, blade convective heat transfer measurements by means of platinum thin films, downstream loss coefficient and exit flow angle determinations by using a new fast traversing mechanism, and free-stream turbulence intensity and spectrum measurements. These different measurements were performed for several combinations of the free-stream flow parameters looking at the relative effects on the aerodynamic blade performance and blade convective heat transfer of Mach number, Reynolds number, and free-stream turbulence intensity.

This book was released on 1996 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research effort is to integrate fluid and heat transfer studies in a heated transonic turbine cascade in order to develop a better understanding of the complex flow physics involved in the coupling of the fluid flow and heat transfer phenomena in an unsteady flowfield. To that end detailed, time resolved aerodynamic and heat transfer measurements are taken in the experiments. Unsteady passing shock is generated in a shock tube and introduced into the test section of the cascade to simulate the shock wave passage similar to an actual turbine environment.

Available in PDF, EPUB and Kindle. Book excerpt: Often there is a distinction between the design of turbomachinery airfoils for aerodynamic performance and durability. However, future aero-engine systems require ever increasing levels of turbine inlet temperature causing the durability and reliability of components to be an ever more important design concern. As a result, the need to incorporate heat transfer predictions into traditional aerodynamic design and optimization systems presents itself. Here, an effort to design an airfoil with both acceptable aerodynamics and minimized heat load is reported. First, a Reynolds-Averaged Navier-Stokes (RANS) flow solver was validated over different flow regimes as well as varying boundary conditions against extensive data available in literature. Next, a nominal turbine inlet vane was tested experimentally for unsteady heat load measurements in a linear cascade. The tests were performed in a reflected shock tunnel to validate the flow solver further at the current experimental conditions, and special attention was paid to leading edge and suction side heat-flux characteristics. The nominal airfoil geometry was then redesigned for minimum heat load by means of both design practice and two types of optimization algorithms. Finally, the new airfoil was tested experimentally and unsteady heat load trends were compared to design levels as well as the nominal vane counterpart. Results indicate an appreciable reduction in heat load relative to the original vane. Thus, it is a credible proposition to design turbine airfoils for aero-performance and durability concurrently.
