Experimental setup for investigation of flows in spherical layers Experimental setup is designed to model flows in spherical layers. The layer of desired thickness is created by liquid-filled gap spacing between internal and external spheres. The spheres are made of organic optically transparent glass. They are hung at two coaxial shafts driven by two independent motors. The working fluid is the solution of silicon oils PMS-200 and PMS-20 with a small amount of aluminum powder for the flow visualization.
External sphere diameter is constant and equal to 300.16 ± 0.07 mm. Inner spheres are replaceable and provide layers with relative thickness in the range from 0.1096 to 1.33. Probe for measurements of the working fluid temperature contacts the fluid at the external surface of the layer. Temperature control system maintains constant temperature, the range of temperature changing is ±0.020С, which guaranties the working fluid viscosity changing within limits of ±0.04%. The driving system holds specified angular velocity and acceleration values with the relative error not exceeding 0.2%. |
