(1986-08-01)The unsteady problem of a viscous incompressible flow in free space is investigated, and a class of exact solutions of the Navier-Stokes equation is given for a general initial condition. This flow field represents several ...
-
(1988-09-01)Acoustic waves emitted by a vortex ring interacting with a fixed solid sphere are studied experimentally and theoretically. The experiments are carried out for two kindsof vortex-sphere arrangement: (A) a vortex ring passes ...
-
(1988-09-01)Using a contour dynamics method for inviscid axisymmetric flow we examine the effects of core deformation on the dynamics and acoustic signatures of coaxial interacting vortex rings. Both "passage" and "collision" (head-on) ...
-
(1988-07-01)Acoustic waves emitted by a vortex ring moving near a thin wedge-like plate of finite width have been studied. The experiments are performed for three configurations: the plate (A) is held edgeways to the direction of the ...
-
(1997-04-30)A new similarity solution is obtained for flow of a uniform stream past an aligned, semi-infinite flat plate. The fluid is incompressible, of constant density, and constant absolute viscosity. A detailed examination is ...
-
(1998-02-28)The present paper deals with the numerical computation of the viscous fingering phenomenon occurring when gas is pushed into a thin layer of liquid between two parallel flat plates. The phenomenon is formulated mathematically ...
-
(1993-03-01)The optimum sail geometry is analytically obtained for the case of maximizing the thrust under equality and inequality constraints on the lift and the heeling moment. A single mainsail is assumed to be set close-hauled in ...
-
(1990-10-01)The governing equations describing the propagation of a moderate planar normal shock wave into a homogeneous dust-gas suspension were formulated and solved numerically using the flux-corrected transport (FCT) technique. ...
-
(1993-01-01)The fluid dynamic phenomena of a high speed liquid jet impact on a deep water surface have been studied using Imacon high-speed photography. Both framing and streak techniques are applied to investigate the initial impact ...
-
(2000-03-31)Results are described from a two-dimensional numerical model in which a cyclonic monopole that moves due to the -effect encounters a northsouth oriented ridge or trough, the height and depth of which is varied. The fate ...
-
(1986-12-01)A technique is presented for the computer detection of temperature fronts in a turbulent shear flow. The detection variable is the product, averaged over a given duration, of temperature fluctuations at a given number of ...
-
(1998-10-31)Axisymmetric vortex breakdown in a steady, inviscid, incompressible flow in a semi-infinite circular pipe is considered analytically. We suggest a new perception of vortex breakdown and compare ours with other approaches. ...
-
(1997-10-31)Development of small disturbances in a one-dimensional fluidized bed is analyzed based on a set of model equations. Nonlinear governing equations for the particle volume fraction are derived from the model equations using ...
-
(1994-05-01)The development of the free surface at the front of an incompressible viscous fluid pushed into a circular pipe is analyzed numerically in the case without surface tension or gravity. Method of computation is an extension ...
-
(1991-10-01)The method of empirical eigenfunctions is developed in a general framework. In particular it is shown that the method of snapshots leads to the determination of the empirical eigenfunctions in any number of dimensions in ...
-
(1995-09-30)A surface or internal solitary wave passing over a shelf is partially reflected and there are at least two transmitted waves. When the incident wave is oblique relative to the shelf, there is a refraction phenomenon as for ...
-
(1992-06-01)The complex function method is applied to screen printing flow with low Reynolds number assuming that the printing ink is Newtonian. The screen printing flow is expressed through a Taylor flow in the corner. The pressure ...
-
(2000-05-31)The velocity-derivative skewness of rotating homogeneous turbulence is analytically derived from the turbulent kinetic energy dissipation rate equation by assuming a simple energy spectrum function. It predicts the cut-off ...
