G. Project: Submarine Fluid Mechanics

Introduction:

This project was more mechanical than civil application which was a fresh idea in my opinion. In the start, we were deciding to study either Turbine or airflow, but we had an issue of finding a more practical object to use and we didn’t have any other systems to compare against. We finally decided to study Submarine fluid mechanics with using a real-life submarine to calculate the drag force and statistical forces.

Summary:

We found out that the drag force of a submarine while its submerged in water is larger than the drag force of air. The important parameter that made the difference is the density of both fluids. The density of air is much smaller than the density of water meaning that the relationship between density and drag force is linear.

The other parameter we discussed is the buoyancy force on both submerged and partially submerged submarine. We found out that the buoyancy force is high while it’s submerged in water than partially submerged in air. Viscosity of the fluid was a big factor in the changes of the buoyancy force. As a high buoyancy force needed to balance the submarine from flipping over while its submerged.

  1. So I guess a submarine in water is very similar to an airplane in the air, except since it’s water theres is buoyancy force? I like how you organized this post, made everything easier to read. Great stuff.
