摘要

The dynamical behavior of fluids, in particular the health monitoring for liquid sloshing in aircraft propellant tank, is the current research focus. In this research, a novel method is proposed for monitoring the dynamic deformation of the liquid sloshing surface at different moments based on transmission-lattice-based geometric phase analysis. An orthogonal lattice pattern is placed under the tested liquid in a container, some calibration tails are printed on the wall of the container, the phase of the distorted transmission-lattice images, and the height information of liquid level are obtained when the liquid surface deformation occurs. On the basis of the mathematical relationship between the out-of-plane deformation of liquid surface and the phase of lattice, the dynamic out-of-plane deformation field of the liquid sloshing surface can be obtained through Newton iteration algorithms. The developed method here has advantages of noncontacting, high precision, low cost, and easy manipulation.
