How to Calculate Strouhal number?
Strouhal number calculator uses Strouhal_number = (Frequency of vortex shedding*Diameter of cylinder)/Freestream Velocity to calculate the Strouhal number, The Strouhal number formula is defined as a measure of the ratio of the inertial forces due to the unsteadiness of the flow or local acceleration to the inertial forces due to changes in velocity from one point to another in the flow field. Strouhal number is denoted by S symbol.
How to calculate Strouhal number using this online calculator? To use this online calculator for Strouhal number, enter Frequency of vortex shedding (n), Diameter of cylinder (D) & Freestream Velocity (V_{∞}) and hit the calculate button. Here is how the Strouhal number calculation can be explained with given input values -> 0.0001 = (1*0.01)/100.
