Unsteady weakly perturbed motion of a body of revolution in a liquid with jet separation
The present paper gives a generalization of the well-known two- dimensional formulation to the three-dimensional case of flow past a body of revolution in accordance with Kirchhoff's scheme. A method is proposed for solving the obtained boundary-value problem using a Green function. This function is constructed in a special system of curvilinear coordinates. To obtain an effective solution, a Laplace transformation is used. Expressions are given for the Laplace transforms of the vectors of the force and torque acting on the body in unsteady motion.
