Experimental investigation of geometry on torque hysteresis behaviour of Taylor-Couette flow

This study investigates the effect of the Taylor-Couette geometry, namely the aspect ratio, Γ, and the gap width ratio, ƞ, on the torque hysteresis reported by [1]. Measurements were taken at two shear Reynolds numbers, Re s, of 5.5x10⁴ and 9x10⁴.The torque was recorded while decreasing or increasing the rotation frequency ratio a=-fo/fi,...
