    Investigation of Thermal Convection and Low-Frequency Microgravity by the DACON Sensor aboard the MirOrbital Complex

    Investigation of Thermal Convection and Low-Frequency Microgravity by the DACON Sensor aboard the MirOrbital Complex


    Abstract The DACON instrument for studying the convection caused by low frequency microaccelerations aboard spacecraft is described. The convection sensor serves as a measuring element of this instrument. This is a cylindrical cavity filled with air, where two crossed differential thermocouples are located. The thermocouple junctions lay on two mutually perpendicular lines parallel to the bases of the cylinder and crossing at its axis. The distances from the junctions to this axis are equal. The lateral surface of the cylinder is thermally insulated, the difference of temperatures on its bases being kept constant. One of the tasks for the sensor is to prepare the data for checking the adequacy of mathematical models of fluid convection under weightlessness conditions and for obtaining quantitative characteristics of the microgravitational medium. The results of ground-based tests of the DACON instrument and the results of experiments with it aboard the Mirstation are presented.
