Analysis of Pressure Field for Flow Past a Circular Cylinder with a Slit

Abstract:

The signal strength, linearity, stability and measurement range of vortex flowmeter are primarily decided by the shape and geometrical parameters of bluff body. A circular cylinder with a slit was found to produce better vortex signal properties by experiments. Based on previous research, pressure distributions of flow past a circular cylinder are studied by numerical simulation. It is found that the intensity of pressure fluctuation caused by vortex shedding of the circular cylinder with a slit is stronger than that of circular cylinder and 0.2d downstream from the center line of slit at one side of cylinder is found to be an optimal position to detect the vortex signal, where d denotes the diameter of the cylinder. Finally the evolution process of vortex shedding is analyzed to explain why the intensity of pressure varies at different positions.
