Abstract Using dilatometry method the thickness of nonfreezing film formed on inner molecularly smooth surface of a thin (micrometer size) quartz capillary was first measured in dependence on temperature and external pressure on ice in the temperature range from 1°C to -0.14°C and pressures up to 8 MPa. The data obtained were used for calculation of disjoining pressure isotherms of nonfreezing ...

Repeat transects of full-depth density and velocity are used to quantify generation and radiation of the semidiurnal internal tide from Kaena Ridge, Hawaii. A 20-km-long transect was sampled every 3 h using expendable current profilers and the absolute velocity profiler. Phase and amplitude of the baroclinic velocity, pressure, and vertical displacement were computed, as was the energy flux. La...

Energy extraction from ocean waves and conversion to electrical energy is a promising form of renewable energy, yet achieving economic viability of wave energy converters (WECs) has proven challenging. In this article, the design of a heaving cylinder WEC will be explored. The optimal plant (i.e. draft and radius) design space with respect to the design’s optimal control (i.e. power take-off tr...

I will discuss two fluid-body interaction problems. The first relates to the experiments of Moret and Zhang (NYU Applied Math Lab, 2008) on a wing with active heaving but passive pitching. The experiments have indicated the existence of a bistable region in flapping frequency where either ”forward” or ”backward” flight may be achieved. I will discuss numerical simulations that are used to bette...
