The experimental results with varying large aspect ratio (AR=3, 6 and 10) at different downstream distance indicate that: i) when x/D> 1.33 in the major axis plane and x/D> 1 in the minor axis plane, the mean concentration, the turbulence intensity, are self-similar and the mean concentration field appear to be Gaussian, ii) axis switching phenomena happens at about x/D [approximately equal to] 7; iii) The experimental results using LIF further verify that the Elliptic jet with varying large aspect ratio has also much higher dilution in a co-flow than an equivalent round jet under the same flow conditions (same momentum flux Me and same flow rate Q).
1), the aspect ratio of the handle is the ratio of the major axis (width of the handle perpendicular to the parting line) to the minor axis (width of the handle parallel to the parting line).
In operation, the outer and inner teeth of the Flexspline and Circular Spline engage across the major axis of the ellipse, so that as the wave generator starts to turn the zone of engagement follows the rotation of the ellipse.
With luck and creativity, it could become the major axis of a revitalised downtown.
This condition occurs when the major axis of the nail plate laterally deviates from the major axis of the digit, potentially causing the distal nail to become ingrown.
The sheath flow mechanism aligns particles with their major axis in the direction of flow.
Is it significant that the major axis of the rectangular base of the Ka'bah is aligned towards the rising-point of the star Canopus over the horizon of Makkah, and the minor axis is aligned to the solar rising at the summer solstice?
In contrast, at the Monterey Wharf sites, leg length and water velocity were significantly correlated, and we explored this correlation using reduced major axis regressions for the logarithm of leg lengths versus the logarithm of either ADM or OM velocity (Fig.
Second, he produces ellipses from the circle whose diameter becomes the ellipse's major axis. He draws perpendiculars from the diameter to the ellipse's major axis so that the ratio of the distance between the perpendiculars' intersection with the circle's diameter and the perimeter of the ellipse to the distance between the perimeter of the ellipse and the major axis will be constant.
The cricoid joint surface is convex superiorly, with its major axis directed in an anterolateral direction.
To determine if the major axis deviated from a vector of isometry with elements 1/[8.sup.1/2] = 0.354, 1000 bootstrap major axes were obtained by resampling (with replacement) from the 177 families of the ancestral population and, for each, the angle of separation of the axis from isometry was computed.
