A wake model for the free-streamline theory is proposed to treat the two-dimensional flow past an obstacle with a wake or cavity formation. In this model the wake flow is approximately described in the large by an equivalent potential flow such that along the wake boundary the pressure first assumes a prescribed constant under-pressure in a region downstream of the separation points (called the...

Numerical simulation of MHD free convection in a two-dimensional trapezoidal cavity hybrid nanofluid has been carried out this research. The is heated sinusoidal from the bottom wall, and inclined walls are cooled while top wall isolated. (MgO-Ag/water) used as working fluid. numerical validated with past papers met good agreement. considered parameters range Rayleigh number (Ra= 103 to 106), H...

This paper proposes a method to measure the inclined angle of an objective image based on the most frequent edge direction. This paper also describes a relation between the measured inclined angles by the proposal method and the visual inclined angles. An edge direction is changed according to the inclination of an objective image. The most frequent edge direction is supposed to show the global...

The contents of this work explore the influence three geometric parameters on controlled cavity collapse at liquid interface and subsequent ejected drop; are angle ejecting nozzle plate (θ), height (H), radius (R) vessel used to enclose within. conducted computational modeling shows that changing from a flat surface inclined in one direction causes droplet diameter decrease, whereas an inclinat...

Abstract The presence of planets or substellar objects still embedded in their native protoplanetary disks is indirectly suggested by disk substructures like gaps, cavities, and spirals. However, these companions are rarely detected. We present Very Large Telescope/NACO high-contrast images the J , H K S bands young star [BHB2007]-1 probing inclined scattered light revea...

The inclined air-curtain technology was applied to build an inclined air-curtain range hood. A draft generator was applied to affect the inclined air-curtain range hood in three directions: lateral (θ=0°), oblique (θ=45°), and front (θ=90°). The three suction flow rates provided by the inclined air-curtain range hood were 10.1, 10.9, and 12.6 m(3)/min. The laser-assisted flow visualization tech...

Differential precession due to the planet's quadrupole moment tends to destroy the alignment of particles in inclined rings. We propose that alignment is maintained by the self-gravity of the ring. This hypothesis predicts that 8i/8a>0 across the ring. If 8i/i0 <(1, 8e/e0 <(1, a8i/8a<(1, and a8e/8a< 1, a further prediction is that 8i/i0 = 8e/e0 • The a and /3 rings of Uranus may be used to test...

[Purpose] The purpose of this study was to identify the effects of changes in support and inclined boards on lower-extremity muscle activity. [Subjects and Methods] The study subjects were 15 healthy adult males. Aero-Step equipment was used as an unstable support, and an inclined board was used to maintain angles of 0° and 20°. Electromyography was employed to analyze lower-extremity muscle ac...
