(19930801)A new approach to the problem of turbulent flows is presented. This approach is based on the conditional averaging of equations for local characteristics of motion, which have a mechanism of selfamplification. In ...

(19870801)Unsteady vortex flow around a fixed solid body in a viscous incompressible fluid is investigated for the case where the velocity field is assumed to vanish at infinity. Consideration of the asymptotic pressure field far ...

(19880901)Incompressible flows stirred at small scale by an anisotropic force lacking parityinvariance can display a large scale instability analogous to the alphaeffect in MHD. Numerical simulations indicate the possibility of ...

(19970215)A new kf turbulence model is proposed, in which the nearwall effect without reference to distance and the nonequilibrium effect are incorporated. In this model, the nonlocal nearwall effect in a general coordinate ...

(19971231)The problem of the capillarygravity waves which may arise at an interface between two stratified fluids of different densities is investigated. Particular attention is paid to the case when two different wave modes move ...

(19920101)The oblique shock reflection over a multiguttered model wedge is investigated at constant Mach number. The experimental parameters were the reflecting wedge angle and the depth of the gutter. It is found that, unlike the ...

(19970131)The flow field of a 90° square duct bifurcation was examined both experimentally and numerically for a Reynolds number of 1200 and equal branch flow rates. Velocity measurements were carried out with a onecomponent LDV, ...

(19950930)We report here an experimental study of the behaviour of a fully developed axisymmetric turbulent jet whose buoyancy is enhanced by volumetric heating over the region between two streamwise stations. The buoyancy enhancement ...

(19980630)A new similarity transformation has been devised for extensive studies of accelerating nonNewtonian film flow. The partial differential equations governing the hydrodynamics of the flow of a powerlaw fluid down along an ...

(19910101)One of the serious drawbacks of the smokewire method, which is a simple but very useful means of flow visualization in lowspeed windtunnel studies, is the short duration of the smoke. In this paper we show that the ...

(19880901)The trajectories of particles advected by nonrandom spatially periodic velocity fields may be chaotic, i.e., extremely sensitive to their initial positions. In the most general case, the area of a cloud of advected particles ...

(19870801)A new nonlinear theory is proposed for twodimensional flow around a body of an arbitrary shape with a finite cavity. The cavity wake is modelled through the concept of displacement thickness. This model of finite cavity ...

(19940801)Our ability to predict the boundary layer transition relies heavily on our understanding of receptivity, the process through which external disturbances excite TollmienSchlichting (TS) waves. In this paper, a nonlinear ...

(19960131)An optimal theory on flow database analysis to capture the flow structures has been developed in this paper, which include the POD method as its special case. By means of the remainder minimization method in the Sobolev ...

(19990430)Recent work has shown that the analysis of bifurcation problems on a large, but finite, interval can yield Landau coefficients which are radically different from those obtained for the problem on an infinite interval. At ...

(19950831)The difference between Stokes' solution for a viscous flow past a sphere and the corresponding generalized solution of the NavierStokes equation is estimated. This estimate implies that Stokes' solution cannot be close ...

(19960930)Simultaneous measurements of the velocity field around and the drag force on a circular cylinder placed laterally in an otherwise uniform water flow were made by means of a laser Doppler velocimeter and strain gauges, ...

(19911101)A highresolution, threedimensional finitedifference numerical study of natural convection flows of a viscous fluid in a differentially heated cubical box is reported. The vertical sidewalls of the enclosure are maintained ...

(19931001)In order to obtain a better understanding of boundarylayer receptivity, the generation process of TollmienSchlichting (TS) waves is investigated in plane Poiseuille flow through a direct numerical simulation on the basis ...

(19880901)We determine stationary states and examine dynamic mergers of isolated piecewise constant regions of potential vorticity in a twolayer quasigeostrophic model. We focus on the behavior of the critical initial separation ...
