Abstract: The variable cycle engine (VCE) is of interest for military and supersonic civil platforms due to its improved operational flexibility. However, the increase in design and control degrees-of-freedom results in a more complex ...

Abstract: A generic impingement cooling system for turbomachinery application is modeled experimentally and numerically to investigate heat transfer and pressure loss characteristics. The experimental setup consists of an array of ...

Abstract: We investigate the unsteady behavior of an in-line jet impingement array of nine jets at a Reynolds number of 10,000 in a narrow channel subjected to a developing cross flow of up to 25% of the bulk jet velocity. To this ...

Abstract: Abstract. This study examines integrating fluidic oscillators into a multi-jet impingement cooling system for turbomachinery, aiming to enhance heat transfer while reducing coolant requirements. The investigated configuration ...

Abstract: Abstract. Increasing aero-engine turbine inlet temperatures and stagnating operational limits of nickel-based superalloys creates the need for new materials and cooling technologies. Ceramic matrix composites (CMCs) can ...

Abstract: Abstract. To fulfill the high flight requirements for a significantly lower environmental impact, new approaches to the design of engines are required. One solution to build an engine as a whole more efficiently is the use ...

Abstract: The current study involves numerical and experimental investigations of circular in-line jets impinging on a heated flat plate. The generic configuration is characterized by nine jets, each with a diameter of D = 0.0152 ...
