We present a simulation technique for the direct simulation of the motion of spherical particles suspended in fluids at low Reynods numbers. We use this method to simulate bidisperse suspensions at varying size ratios of the suspended spheres and compare to analytic results of Batchelor for the low concentration regime. We find that the pair correlation functions indicate that three body hydrod...

In this experimental study, we report on the mixing properties of interfacial colloidal floaters (glass bubbles) by chemical and hydrodynamical currents generated self-propelled camphor disks swimming at air-water interface. Despite reaching a statistically stationary state for glass bubbles distribution, those always remain only partially mixed. This intermediate results from competition betwe...

The unsteady, incompressible electroviscous fluid flow has been investigated with thermal energy transmission across two parallel plates. upper plate is in motion, while the lower one stationary. governed by Navier-Stokes equations, which are combined Maxwell equation. system of nonlinear PDEs simplified to a ODEs along their boundary conditions using Von-Karman's transformation. For problem's ...

We present a family of exact equilibrium solutions the Euler equations consisting single helical vortex with an axial flow component along core. Relations between vorticity, velocity and streamfunction are analytically derived in inviscid framework constitute generalization relations valid for rings (Batchelor, 1967 An Introduction to Fluid Dynamics . Cambridge University Press). Through Navier...

Developments in theoretical investigations and experimental techniques are reaching a level of maturity for which it is finally becoming possible to answer some the most pressing questions turbulence. The prevailing classical theories all have their strengths drawbacks based on respective principal assumptions. To better understand implications these assumptions, we developed theoryintensive st...

Historicamente, a participação de mulheres em posições destaque no mercado do audiovisual é bem inferior à homens. Na animação essa realidade se repete. Nos grandes estúdios, como Disney, as eram contratadas para exercer funções repetitivas, consideradas inferiores. Cabendo aos homens mais importantes e que envolviam criatividade. história da animação, por tenhamos nomes Lotte Reiniger, Claire ...
