Comparison study on flow fields in vortex flow sensors with circular cylinder and trapezoidal cylinder bluff bodies
The flow fields in vortex flow sensors with circular cylinder and trapezoidal cylinder bluff bodies are investigated respectively. Then the characteristics of two flow fields are compared by numerical simulations while the mechanism of vortex shedding is analyzed in detail. Finally, the reason, which leads to different vortex shedding frequency and effects the relationship between Reynolds number and Strouhal number, has been specified as the size of wake flow region behind bluff body where the vortex generated.
