Abstract
The simulation of Couette flow inside the circular gap between coaxial cylinders is observed due to the difficulty of the experimental implementation of the equal plane one, especially for rarefied gas conditions and high Knudsen numbers. Geometry configuration of the experimental facility have been defined in order to minimize speed profile deviation inside the gap from linear shape, existing in case of laminar flow and preventing appearance of Taylor – Gërtler vortexes with chosen flow parameters. The previous stage, that was conducted using the hot-wire anemometer in atmosphere pressure conditions has shown the efficiency of the facility and sufficient agreement of calibration data, received using considered calibration method and data of standard calibration approach when the model wind tunnel DISA is applied.
