Question

In vortex shedding flow meter, if the distance between two vortex is 12, then the diameter of bluff is_____

Answer 1

Answer:

Vortex flow meters are a direct type of flow-measuring device with operating fundamentals based on the Von Karman Vortex Street principle. In this instrument, a bluff body or shedder bar is arranged at the center of flow path. When the fluid passes through it, disturbances in the flow called vortices are alternately formed on both sides of the shedder. These vortices thus formed are shed just after due to the flow stream forming a vortex street as per Karman Vortex Street principle (see Figure IV/4.2-4).
