Sentence examples for mean gas flow from inspiring English sources

The silencer contains a bulk reacting acoustic absorbent which is separated from a mean gas flow by a perforated screen.

Acoustic oscillation can be induced in a closed branch tube by a mean gas flow in a trunk tube passing the opening of the branch tube.

The presence of a uniform mean gas flow in the "airway" of the silencer is taken into account, as is anisotropy of the absorbent.

The theoretical model is based on a hybrid finite element method which enables the inclusion of bull nose fairings and a perforated screen separating the mean gas flow from a bulk reacting porous material.

It is well known that the acoustic performance of a splitter silencer changes under the influence of the convective effects of a mean gas flow and so in this article a theoretical model is developed to include the effects of mean flow.

The validity of this assumption is investigated here, and the relative speed and accuracy of two analytic methods are compared to two numerical methods for a uniform dissipative silencer that contains a bulk reacting porous material separated from a mean gas flow by a perforated pipe.

Periodic liquid feeding of the ON OFF type is investigated — at sufficiently high frequencies to be classified as "fast" mode of induced pulsing — in the range of mean gas and liquid flow rates corresponding to the steady "trickling flow" regime.

Gas/liquid down-flow in packed beds is studied, under periodic liquid feeding (at sufficiently high frequencies to be classified as "fast" mode of pulsing), in a range of mean liquid and gas flow rates within the steady "trickling flow regime".

With liquid-induced pulsing flow this means that higher gas flow rates are necessary to induce pulses as the length of the liquid-rich region decreases.

The acceleration of solid particles by means of a gas flow expanding to supersonic regimes is critical to process efficiency; previous studies rarely address the particle feed rate as an influential parameter for the acceleration.

A theoretical model is presented, describing sound propagation in infinite two-dimensional planar silencers incorporating an arbitrary number of bulk-reacting, anisotropic, sound-absorbing splitters, with uniform mean flow in the gas flow passages; a corresponding computational scheme is also outlined.
