    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.

    Particulate flow and blade erosion - article pay-per-view - 25€ / article

    €0.00

    Solid particle erosion problems are of great concern in gas turbines, steam turbines, boilers, fluidized beds, aircraft engines and many other systems. Erosion may cause a significant decrease in the operating lifetime of gas turbine engines or other systems operating in dusty environments or when ash particles are present, as in coal gasification. Particle trajectory studies provide information on particle impact and location, and erosion studies indicate the amount of material removed with each particle impact. The course presented the principles involved and the state-of-the-art in erosion prediction for engines subjected to solid particle ingestion. Particle deposition may have as detrimental an effect on turbine performance as blade erosion. The mechanism of particle formation and particle adhesion to the blade surfaces were discussed in depth with particular emphasis on fluidized bed and coal-fired turbine applications. Learn More
