“…Berman A. et al [41] applied numerical analysis and an experiment focusing on the case of asynchronous precession, and found that nonlinear surface waves can exist on the liquid layer in the form of relatively weak hydraulic jumps with waves generated by it. Similar studies by Chato D. and Dalton P. [42] and Yoshizumi F. [43] are purely experimental and numerical.…”

This article analyses the problem of automatic balancing rotors with a liquid balancer, which is a cylindrical chamber partially filled liquid of a certain density. This problem is related to the problem of the dynamics of bodies with cavities partially filled with liquid. As part of this task, we analyzed disturbances in the relative motion of the fluid in the ABD chamber caused by the Coriolis force inertia. The distortions of the free surface of the liquid were found, resonant phenomena in the flow of the working fluid were investigated, and the physical explanation of the received results given should be taken into account when designing the corresponding ones self-balancing devices. It was established that the axial component of the Coriolis inertial force causes peculiar wave phenomena in the correcting fluid movement. For the given nature of undisturbed motion, the conditions of this phenomenon’s occurrence are determined only by the geometric dimensions of the cylindrical chamber and the thickness of the liquid layer in undisturbed motion, and do not depend on the intensity of rotation of the liquid, nor on its density. It is shown that a decrease in the “ABD chamber height–radius” ratio leads to stabilization of the movement of the system. Experimental verification has been performed; theoretical results on the developed stand for work research rotor system with a vertical axis of rotation.

“…[7,8]. A detailed experimental study of liquid motion in spinning, nutating tanks was reported in [9] to determine the effect of such liquid motion on the stability of the spacecraft. However, to the best knowledge of the authors, study on the flow field during propellant draining in a spinning tank with and without baffles for launch vehicle application is not available in open literature.…”

Computational Fluid Dynamics (CFD) study of liquid oxygen draining in a spinning tank with and without baffles is carried out for hybrid propulsion rocket. The effect of tank spinning and the presence of baffles on the vortex formation and unusable propellant mass is brought out in this work. The interface of the draining propellant is captured using the Volume of Fluid (VOF) framework while the motion of baffles is simulated through mesh motion technique. Initially, analysis of liquid oxygen draining is carried out in a stationary tank without baffles. It is found that that a vortex is formed in the tank and gas entry in the feed line happens at 21s resulting in unusable propellant of 1.9kg. Subsequent analysis of liquid draining in a spinning tank without baffles shows that gas enters into the feed line earlier as compared to the stationary tank. Finally, the analysis is carried out for propellant draining in spinning tank with baffles. It is found that the momentum imparted by the baffles to the draining fluid increases the unusable propellant mass further compared to tank without baffle.
