Method for demonstration of Couette-flow between two coaxial cylinders rotating relative to each other for teaching physics, involves providing process gas in cylinder rotatable by motor, and identifying resulting gas flow by indicators
Method for demonstration of Couette-flow between two coaxial cylinders rotating relative to each other for teaching physics, involves providing process gas in cylinder rotatable by motor, and identifying resulting gas flow by indicators
The method involves providing a process gas (11) under continuum condition with Knudsen numbers less than one in an outer cylinder (12) that is rotatable by a rotation motor (14), and identifying resulting gas flow by indicators i.e. impeller. A time constant is utilized for determining an adjustment of stationary flow of the process gas by a pressure reduction of the process gas. A set of dilator components is provided for illustrating rotation phenomena of the gas.
