(19861201)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 ...

(19900701)Comprehensive numerical solutions of threedimensional flows of an incompressible viscous fluid confined in a square cubic cavity are presented. The flow is maintained by the upper surface of the cavity, which slides in ...

(19881101)In a converging nozzle, fluid is shown to be compressed to a very high density, especially in the supersonic region, if the initial Mach number of the fluid is large. Thus it is shown that spherical implosion can be used ...

(19981031)Axisymmetric vortex breakdown in a steady, inviscid, incompressible flow in a semiinfinite circular pipe is considered analytically. We suggest a new perception of vortex breakdown and compare ours with other approaches. ...

(19971031)Development of small disturbances in a onedimensional 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 ...

(19940501)Flow field near the front of an incompressible viscous fluid pushed into a circular pipe is analyzed theoretically and observed experimentally. In the theory, an approximated stream function for a steady state near the ...

(19940501)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 ...

(19920401)The classical slender body theory is generalized to the problems of a slender body of revolution moving with an angle of attack, in very close proximity to curvedground and wavingwater surfaces. The flow problems are ...

(19911001)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 ...

(19950930)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 ...

(19941101)The reflecteddiffracted shock wave which develops when a regular reflection interacts with an expansive corner was investigated analytically by means of the shock dynamics theory. The results were found to agree with the ...

(19920601)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 ...

(20000531)The velocityderivative 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 cutoff ...

(19910201)Generally speaking, velocity measurement devices such as hotwire and LDV (laser Doppler velocimeter), which may be called Eulerian type flow measurement devices, can record temporally continuous and precise velocity ...

(19990131)Extensive hotwire anemometer measurements have been carried out in a flat plate boundary layer undergoing transition from laminar to fully turbulent flow. The main aim of the present work is to develop a convenient and ...

(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 ...
