Speed Control in Microwave Drying Of Apple
2010 Pittsburgh, Pennsylvania, June 20 - June 23, 2010, 2010Microwave drying of apple at constant temperatures of 50 – 80 °C follows typical drying curves. The middle stage of the drying process shows a faster drying speed and accelerated moisture evaporation. Meanwhile, more flavors are lost, surface color is degraded, and charring often occurs.

Speed of crack propagation in dry aqueous foam
EPL (Europhysics Letters), 2010Applying pressure driving to a single layer of aqueous foam bubbles induces a void propagation that is a surprisingly close analog of dynamic crack propagation. Depending on the rate of applied stress, both a ductile and a brittle mode of propagation are observed, the latter at much higher propagation speeds.

New bearing materials for high speed dry operation
Wear, 1988Abstract Results are presented from a project to modify the design of a compressed air vane motor so that it would run equally well under completely dry conditions, or in the presence of oil or water. The solution lay in the development of a new dry bearing material composed of a mixture of polytetrafluoroethylene, glass fibre and lead, which gave ...

Sustainable High Speed Dry Cutting of Magnesium Alloys
Materials Science Forum, 2012Magnesium (Mg) components can significantly reduce energy use due to their low densities compared to the majority alloys. Mg alloys are often machined to fit individual cases. However, process mechanics by high-speed dry cutting of Mg alloys are poorly understood.

High-speed droplet impingement on dry and wetted substrates
Physics of Fluids, 2020High-speed droplet impact is of great interest to power generation and aerospace industries due to the accrued cost of maintenance in steam and gas turbines. The repetitive impacts of liquid droplets onto rotor blades, at high relative velocities, result in blade erosion, which is known as liquid impingement erosion (LIE).
