The thesis focuses on improving the flowrate of the Knudsen gas pump. The Knudsen pump uses thermal transpiration as the driving mechanism to pump gas. It is a motionless gas pump as the pump does not require any moving actuators for pumping. The...
Dermal wounds, including bed sores, pressure ulcers, and diabetic ulcers have a large impact on American healthcare costing up to $7 billion per year. Adequate pharmaceutical remedies applied at constant rate could prove to increase the healing...
The Knudsen pump works on the principle of thermal transpiration. As a result of requiring a thermal gradient, channel hydraulic diameter smaller than the mean free path of the gas being pumped, and having no moving parts, the Knudsen pump features...
