    Plasma flow control: Fundamentals, modeling and applications article pay-per-view 25€/article

    €0.00

    Advances in aero-thermodynamics, aero-elasticity and aero-acoustics largely depend on the understanding of the flow structures, and the ability to control them. The first lecture note reviews the various approaches that are being followed for plasma flow control. The fundamental interaction mechanisms are presented together with the challenges associated to their implementation depending on the flow regime. A presentation on the mechanisms for the generation of momentum transfer using offset dielectric barrier discharges follows, focusing on the physics of the breakdown formation. The next lecture note addresses phenomenological models that can be used in conjunction with CFD codes, from simple algebraic equations to complex set of partial difference equations. The first part is concluded with the use of DBD actuators in various applications for internal and external flow control, over a range of Mach numbers from 0.1 to 3.5, in a wide static pressure range from 0.1 to 9 bar.

    Advanced high-temperature instrumentation for gas turbine applications article pay-per-view 25€/article

    €0.00

    In aero-engines as well as industrial gas turbines, the drive to higher efficiency is steadily raising the pressures and temperatures in the engines, and this further increases the challenge to instrumentation. Accurate measurements in the hot components of gas turbines (including combustion diagnostics) are recognized as a major need for the assessment of engine component health and performance. High temperature instrumentation is required not only during product development for the validation of new designs or component life prediction methods, but also in service for health monitoring and optimum engine control.

    Liquid fragmentation in high-speed flow article pay-per-view 25€/article

    €0.00

    Liquid injection into compressible crossflow has several interesting applications such as fuel injection in supersonic or hypersonic scramjet engines, thrust vector maneuvering of high speed aerial or space vehicles, and film cooling used in the thermal protection systems of space vehicles that experience atmospheric entry. The field involves many disciplines, and it is a complicated multi-phase flow field especially for compressible crossflow cases, with a unique flow topology including shock-shock and shock-boundary layer interactions. High aerodynamic shear forces, fragmentation, penetration and atomization of the liquid jet are important features that deserve detailed analyses.

    Introduction to optimization methods for multidisciplinary design in aeronautics and turbomachinery article pay-per-view 25€/article

    €0.00

    Innovative optimization and design techniques, both for aircraft (manned or unmanned UAV/UCAV) and engine systems, are now rapidly moving from research labs to industrial integrated platforms used by collaborative teams. These platforms aim at maximum performance in multidisciplinary context by combining several criteria like aerodynamic efficiency, safety, drag, losses, weight, strength, heat fluxes, emission, noise. To reach concurrently this level of excellence, emergent optimization and design methodologies require more and more robust and efficient associated software for daily use in industrial collaborative design environments.

    Experimental determination of dynamic stability parameters article pay-per-view 25€/article

    €0.00

    The stability of aerial vehicles has always been one of the most important topics studied for a safe and smooth flight. An aerial vehicle should have the tendency to return back to a stable position, when it is disturbed from its original path. Dynamic stability is usually thought as the vehicle's response over time when disturbed from a given angle of attack, slip or bank. The advent of flight at high angles of attack has revived our interest in the dynamic stability of aircrafts and missiles. One of the biggest problems in studying dynamic stability is the accurate determination of dynamic stability parameters, in other words, the damping coefficients.
