The experimental studies results of the inertial flow structure of a viscous incompressible fluid that rotates in the toroidal tanks with application to the liquid fuel dynamics on the spacecraft board. The dependencies of the structure of the near-wall flow, and graphical expressions for circular moments of the viscous fluid friction against the walls of the vessel are presented. The exponential curves of torque dependences during the time show the nonlinear relationship of inertial flows power influence on the toroidal reservoir walls. The presented experimental results form the base for the future inertial axisymmetric flows numerical modeling by the finite element methods. The paper provides empirical relationships for force impact of the mobile liquid and practical recommendations for the use of experimental measurements results.References
