- Abstract
The objective of the CDIC (Chemically Driven Interfacial Convection) module experiment is to create chemo-hydrodynamic pattern formation at a “two-dimensional” interface of two liquids, organic and aqueous. The phenomenon is observed by interferometer and shadowgraph. The PI is Dr. K. Eckert, Technical University of Dresden, Germany. The CDIC flew on MASER 10 which was launched 2 May 2005 from Esrange in Northern Sweden. The CDIC-2 is planned to be flown on MASER 11 in fall 2007. This paper will report on the design and technical results of the CDIC experiment and the modifications planned for the CDIC-2 experiment module. The MASER sounding rocket is propelled by a 2-stage solid fuel motor, which gives a 350 kg payload 6 minutes of microgravity. Swedish Space Corporation (SSC) carries the MASER mission out for the European Space Agency. The CDIC experiment was carried out in four identical Hele-Shaw cells. The phenomenon was observed by two types of optical instruments, interferometers and shadowgraphs. The images of the optical instruments were recorded by digital high-resolution 1600x1200 pixel cameras. The four camera images were by the Digital Video System lossless stored on-board, and were also down-linked in real time for guidance during cell filling at 10 frames per second with compression factor of 60. At start of microgravity, the liquids were injected into the cells. The video cameras were switched on before microgravity and enabled the PI team to monitor, via the digital video down-link, the crucial first phase of the liquid injection in the cells. Based on the real time images, the scientists could adjust the filling by sending telecommands. The experiment progress was visually observed throughout the remaining microgravity period. The on-board recorded uncompressed image data could be retrieved already at the launch site, to be analyzed by the scientists. The experiment success rate is estimated to be 100%. The CDIC-2 experiment module, currently in the study phase of the development, will have similar overall design. However the CDIC-2 will feature the following novelties: a capillary cell with an internal diameter of 6 mm and a length of 50-100 mm, a light sheet illumination, aimed for the capillary cell where Particle Image Velocity study will be performed, a high-resolution camera, 1920x1080 pixels, which corresponds to the capillary cell object field, a new hydraulic system for injecting the experiment liquids and the tracers, Hele-Shaw cells with reduced dimensions compared to the ones used in CDIC.
