The lean blow-out performance of an engine and the ability to re-ignite the flame, especially at high-altitude conditions, are important aspects for the safe operability of airplanes. The operability margins of the engine could be extended if it was

The effects of inert diluents in the fuel mixture of a model swirl stabilized gas turbine combustor, under thermoacoustically unstable limit cycle operation, were studied experimentally. The measurements included particle image velocimetry (PIV), hig

Development of gas turbine combustors operating on the lean premixed mode has been hindered by the establishment of thermoacoustic instabilities that may prove challenging to the structural integrity of the engine. Transitions between a quiescent sta

Background: Cardiac performance depends on optimum ventriculoarterial coupling which is impaired in patients with heart failure (HF). Galectin-3 is a mediator of myocardial fibrosis and remodeling, and is associated with clinical status in patients w

In diesel engines, during a load increase, due to poor combustion from the fuel/air mismatch, excessive exhaust smoke may be caused. One possible measure to reduce smoke emissions is the use of compressed air injection into the manifold downstream of
