Ultrasonic Reconstruction and Measurement Technology for Complex Propellant Liquid Surface in Storage Tanks
摘要
Abstract
In microgravity environments,liquid propellant surface inside the storage tank exhibits complex behaviors,and currently no measurement methods are specifically designed for gas-liquid interface under these conditions.Due to its excellent penetration through metals,non-contact measurement features,and imaging advantages,ultrasonic techniques have become a prominent research focus in the field of gas-liquid two-phase flow detection.This paper explores applications of ultrasonic methods for measuring the propellant liquid surface within tanks.First,based on ultrasonic reflection tomography principles,a novel method for reconstructing the complex propellant liquid surface is proposed—referred to as the elliptical reflection micro-element method,accompanied by the development of the corresponding algorithm.Second,an ultrasonic experimental system for measuring the propellant liquid surface is designed and established.The system enables synchronous acquisition of 16-channel 80 MHz ultrasonic signals and supports the sequential excitation of 16 ultrasonic transducers.Finally,a two-dimensional reconstruction experiment of the complex liquid surface is carried out,with results showing that the average relative error of the reconstruction does not exceed 9.0%.This study demonstrates the successful implementation of ultrasonic-based reconstruction and measurement techniques for complex propellant liquid surfaces.关键词
