CHARACTERISTICS OF THE FLOW OF AN INCOMPRESSIBLE FLUID IN A GRAVITATIONAL FIELD
Mathematics of the USSR-Sbornik, 1990Two- and three-dimensional problems of the motion of an incompressible fluid of variable density in a gravitational field are considered. Integrodifferential equations for the characteristics are obtained, and the existence and uniqueness of a solution of the Cauchy problem in finite time is proved in the two-dimensional case and in infinite time in ...

General Characteristics of Hypersonic Flow Fields
The Journal of the Royal Aeronautical Society, 1959SummaryThe object of this paper is to give a brief account of the development of the study of hypersonic flow over the past three decades, and to stress some of the ways in which hypersonic flow differs from supersonic flow. In some of the early work on the subject a wrong emphasis was given to the study of flows with attached shock waves and to the ...

Characteristics of cross-field flowing molecular lasers
1970 International Electron Devices Meeting, 1970In the cross-field laser, the premixed gas flow is channeled transveres to the stabilized electrical discharge column. The crossed magnetic field, mutually perpendicular to the discharge axial electric field and the gas flow velocity, is used to stabilize the discharge parallel with the optical axis of the resonator.

Analysis of the Flow Characteristics of Multiphase Flow Fields in the Mixing Agitator
Applied Mechanics and Materials, 2014The numerical simulation for the flow characteristics of multiphase flow fields in the multiple-blade mixing agitator is carried out by means of combining of the large eddy simulation (LES) and multiphase flow model. Then the flow pattern changes and material mixing rule at different speed conditions are analyzed.

Velocity field characteristics of a swirling flow combustor
AIAA Journal, 1983Data for reacting and nonreacting flows obtained by laser anemometry in a swirl combustor are reported and discussed. The combustor consists of two confined, concentric swirling jets. The central jet flow is premixed methane/air; the annular jet flow is air.

Flow field characteristics of isolator with fluidic injection
International Journal of Turbo & Jet-EnginesAbstract The present work investigates the effect of secondary fluidic injection on the flow-physics of a supersonic stream within an isolator. An isolator with a length-to-height ratio of 4.5 and an entry Mach number of 2 was chosen for this investigation. The experimental investigations were conducted at a nozzle pressure ratio of 4
