Wake Frequency Calculator
A wake frequency calculator is a valuable tool used in various engineering applications, particularly in the fields of fluid dynamics and aerodynamics. It assists engineers and designers in determining the wake frequency of objects moving through a fluid medium, such as air or water. Understanding wake frequency is essential for optimizing the design of vehicles, aircraft, and other objects that interact with fluid flow.
Formula
The formula for calculating wake frequency (WF) is: WF = (D * V * St) / d, where D is the distance, V is the velocity, St is the shaft tolerance, and d is the diameter.
How to Use
Using the wake frequency calculator is straightforward:
- Enter the distance (D) in the appropriate input field.
- Input the velocity (V) of the object moving through the fluid.
- Enter the shaft tolerance (St) relevant to your application.
- Provide the diameter (d) of the object in question.
- Click the “Calculate” button to obtain the wake frequency (WF).
Example
For instance, if you have a distance (D) of 10 meters, a velocity (V) of 5 meters per second, a shaft tolerance (St) of 1.5, and a diameter (d) of 2 meters, you would input these values into the calculator. The calculation would yield a wake frequency (WF) of 37.50, indicating the rate at which the wake oscillates.
