An experimental study of turbulence generation and decay in Taylor-Couette system due to an abrupt stoppage

Abstract : This study presents an innovative approach towards the generation and decay of turbulence in the Taylor-Couette system. The cylinders were brought to an abrupt stoppage that generated turbulence in the system, which was initially in the laminar ow region. Two complementary experimental approaches, namely visualizations and stereo-PIV measurements, were used to better understand the presented phenomenon for three different configurations at multiple rotation rates but always starting in the laminar ow region : only external cylinder, co-rotation and counter-rotation. For only external cylinder rotation, the lowest threshold limit of outer Reynolds number to was found to be
