DYNAMIC AFFECTS OF INNER STABILIZING DEVICES ON INERTIAL FLOWS OF VISCOUS INCOMPRESSIBLE FLUID IN LIMITED VESSELS

 

Abstract. The viscous incompressible flows of liquid fuel reservoirs in space vehicles tanks are investigated. The results of experimental researches of internal flows influence on rigid tank walls are presented. The analysis of graphic dependences of forces of liquid viscid friction and flows dynamic influence circular moments are conducted on flows. The experimental results for velocity profiles helps to design the rational baffles structures and forms the velocity fields which are the basis for inertial torque formulation and helps to calculate the dynamic affects of inertial flows. The practical recommendations of the rational use of internal devices from point of sizes, mass and affecting efficiency liquid are made.


Keywords: fluid inertial flows, flat baffles, Reynolds and Rossbi numbers, viscous torques of fluid flows on rigid tank walls.
