Swing phase control-From fluid mechanics to microprocessors

HRC adjustable pneumatic swing-phase control knee.

Since 1972 the Hyogo Rehabilitation Centre has been developing a variable-resistance-type pneumatic control device, the HRC Adjustable Pneumatic Swing-Phase Control Knee. Successful field tests have been carried out on 20 cases with Model IV since 1973 with only a limited number of mechanical troubles. This paper introduces the HRC adjustable pneumatic swing-phase control knee with follow-up st...

Environmental multi-phase fluid mechanics: what, why, how, where to?

In April 2009, the Springer journal Environmental FluidMechanics published a special issue on ‘‘Recent Advances on Multi-Phase Flows of Environmental Importance’’ (Env. Fluid Mech., Vol. 9, No. 2, 2009), edited by the same authors of this editorial [1]. That issue featured six high-calibre papers devoted to a range of multi-phase flow topics relevant to environmental and geophysical flows [2–7]...

From the Boltzmann equation to fluid mechanics on a manifold.

We apply the Chapman-Enskog procedure to derive hydrodynamic equations on an arbitrary surface from the Boltzmann equation on the surface.

Multiscale Particle-In-Cell Method: From Fluid to Solid Mechanics

Fluid Mechanics from the Beginning to the Third Millennium*

Although the christening of the discipline is a relatively recent undertaking, fluid mechanics goes back to the time of archaic Homo sapiens. The art of fluids in motion was born when quite empirically, unceremoniously and without a hint of what either a fluid or mechanics is, the resourceful inhabitants of the planet Earth discovered that a streamlined object travels farther as compared to a b...
