Estimation of Drag Coefficient of a Bare Hull of a Submarine Moving in Different Directions
We developed a numerical model using Computational Fluid Dynamics to simulate the movement of a submarine with spherical heads moving in different directions and at different speeds in a viscous and incompressible fluid. Afterward, the drag coefficient of the submarine is estimated for different scenarios. Using the Nonlinear Least Squares Marquardt-Levenberg algorithm, we fit the best curve to the results of the drag coefficient based on length-to-diameter ratio of the bare hull and the Reynolds number. For different directions, regression equations are presented to estimate the drag coefficient.
