Rotation of the cylinder in the flowing streamAbstract
The features of modeling the dynamics of the rotational movement of a cylindrical rod in a homogeneous flow of a viscous liquid are considered. The angle of attack, the angle of rotation, and the angular velocity of the rod are studied numerically. The results of solving the boundary value problem using the numerical method in Mathcad are presented. Graphs are presented in dimensionless variables. It is obtained that the angular velocity of the rod under the action of gravity increases to the maximum value over time, and then tends to zero. In this case, the angle stops changing, which means that the equilibrium position has been reached.
