It was seen earlier that the power coefficient Cp and the velocity ratio λ were primary parameters for design and performance and can be given in terms of the rotor geometry, that is, the number of blades and their airfoil section as expressed by lift/drag ratio L/D. Some of the ...
where T is the actuation period and uexitt is the instantaneous SJ exit velocity at the center of the slot. The SJ momentum coefficient is estimated as (2)Cμ=AjAw/2ρjUj2ρ∞U∞2 where Aj is the area of the rectangular slot, Aw/2=b0c/2 is the half-wing surface, and ρj,ρ...
The theoretical velocities in the preceding table must be reduced by multiplying by a “coefficient of discharge,” which varies with the orifice and the pressure. The following coefficients are used for orifices in thin plates and short tubes....
, then on the basis of the ratio of actual flow rate to theoretical flow rate the flow rate coefficientsin cavitation-free mode andin cavitation mode of discharge are determined, then the contraction coefficientis determined by following formulaand the velocity coefficientis determined by formula....

Further, since the layered piezoelectric film is oriented along the (111) plane which is the polarization axis, the layered piezoelectric film is hardly influenced by the expansion coefficient of the substrate. According to a thirteenth embodiment of the present invention related to the twelfth embo...
In the research scope of present work, the flow structure, total pressure loss coefficient and overall cooling effectiveness are the most expected under the conditions of lower turbulence intensity and higher mainstream velocity (Tu = 1%, Vm = 90 m/s). Keywords: sweeping jet; fluidic oscillator...
In addition, when the ingested material sticks to the surface of components, it can lead to a degradation of the flow path, clogging of fuel nozzles or blockage of cooling holes [1]. Even though typical particles separators can remove particles larger than ≈80 μμm, smaller particles pass...
This excellent agreement confirms that the permeability and the local heat transfer coefficient have been chosen appropriately to recover the information lost in the averaging process.

The coefficient of the total aerodynamic drag of the plate Сх determined with due regard to the energy consumptions on the air blowing into the external flow, is of special interest though its evaluation in laboratory conditions is rather problematic. There are several ways to determine this va...
