The work consists of (1) the development of a new measuring method for Dynamic Surface Deformation (DSD, hereafter) of cylindrical bridge of high Prandtl number fluid and (2) the study of g-jitter effect on DSD in a simulated g-jitter environment. In the first work, a technique based on Temporal Speckle Pattern Interferometry (TSPI) is developed to make two-dimensional measurement of DSD in oscillatory thermocapillary convection. The technique is designed to have a resolution of better than 0.1 um and be applicable to a curved liquid surface. Its performance is verified through a series of measurements targeting a flat mirror, a glass rod and a liquid bridge, all of which show dynamical surface displacement or deformation. The success of the measurement is due to the special phase-unwrapping algorithm devised for the measurement of oscillatory surface displacement or deformation. In the second work, effects of g-jitter on the measurement of DSD caused by the oscillatory thermocapillary convection in a liquid bridge are studied experimentally. A vibration table driven by a piezoelectric actuator is constructed to generate g-jitters of realistic amplitude and frequency spectra. A micro-imaging displacement meter is used to measure DSD in the presence of g-jitter. It is shown that the natural DSD in the oscillatory state of thermocapillary convection is well separated in the frequency domain from that caused by harmonic and non-harmonic g-jitters.

内容記述 | This report describes experimental studies conducted at Yokohama National University during 2003 JFY as a part of the Project Research on Marangoni Convection of National Space Development Agency of Japan (NASDA) (now JAXA). The work consists of (1) the development of a new measuring method for Dynamic Surface Deformation (DSD, hereafter) of cylindrical bridge of high Prandtl number fluid and (2) the study of g-jitter effect on DSD in a simulated g-jitter environment. In the first work, a technique based on Temporal Speckle Pattern Interferometry (TSPI) is developed to make two-dimensional measurement of DSD in oscillatory thermocapillary convection. The technique is designed to have a resolution of better than 0.1 um and be applicable to a curved liquid surface. Its performance is verified through a series of measurements targeting a flat mirror, a glass rod and a liquid bridge, all of which show dynamical surface displacement or deformation. The success of the measurement is due to the special phase-unwrapping algorithm devised for the measurement of oscillatory surface displacement or deformation. In the second work, effects of g-jitter on the measurement of DSD caused by the oscillatory thermocapillary convection in a liquid bridge are studied experimentally. A vibration table driven by a piezoelectric actuator is constructed to generate g-jitters of realistic amplitude and frequency spectra. A micro-imaging displacement meter is used to measure DSD in the presence of g-jitter. It is shown that the natural DSD in the oscillatory state of thermocapillary convection is well separated in the frequency domain from that caused by harmonic and non-harmonic g-jitters. It is concluded that the DSD measurement in the future ISS experiment is feasible even in the presence of g-jitter there. | |||||
