Abstract
We are using a vibrating wire method to measure hydrogen gas viscosity under high pressure. Vibrating wire viscometers are based on the principle that small a wire oscillating in a sample fluid experiences a residence to motion that is related to the viscosity of the fluid. Due to the simple and robust construction, vibrating viscometers well suited to extreme conditions such as high pressures and high temperatures. In this time, we are attempting to measure hydrogen gas viscosity in the range of pressures from 0.1 to 1.0MPa and room temperature. And, we are investigating the possibility of using this method for higher temperature hydrogen gas viscosity measurement.
