Rapid distortion theory as a means of exploring the structure of turbulence,onditions and forcing of the particular flow and, for high Reynolds numbers, the universal small scale motions. Evidence is presented that in shear flows and flows near boundaries the large scale structure of many different turbulent flows is similar. The analysis and understanding of different type

Spatiotemporal Chaos in Interfacial Waves,n different spatial regions, and from fully developed turbulence by the absence of a cascade. Several experimental and theoretical examples of spatiotemporal chaos are briefly reviewed. Parametrically forced surface waves provide a favorable context for the study of spatiotemporal chaos since the nu

The Complementary Roles of Experiments and Simulation in Coherent Structure Studies,theory or even an objective, mathematical definition of CS. What started out as a promise for a mechanistic explanation for fluid turbulence—as researchers found or reinvented CS in their ‘search for order in disorder’ and presumed to have discovered a deterministic, tractable route to turbulence ph

Remarks on the Navier-Stokes Equations,lobal weak solutions are constructed. They enjoy the properties that the spatial integral of the vorticity magnitude is a priori bounded in time and that the space and time integral of the . power of the magnitude of the gradient of the vorticity is a priori bounded.

Probabilistic Multifractals and Negative Dimensions, them, one can extract the positive and negative parts of the .(α) function with exponentially less work than by using conventional boxcounting methods. When the underlying multiplicative structure is not known, both methods of computing negative dimensions can give spurious results at finite resolu
