Major activity has been directed toward maintenance and modification of the PDU. Currently, final assembly and preparation are in progress for tests to be conducted. The last part of commissioning test TP-M001-4, which is a functional checkout of the model structure and associated subsystems, has been completed. From the experiments performed in a bed of wide size particle distribution, the two-dimensional, wedge-shaped pitot tube with continuous gas purge successfully prevented the plugging of the tube holes over a long period of operation and simultaneously provided the required sensitivity of measurement. The pitot tube was calibrated in the wind tunnel at 0, 250, 310, and 390 cm/sup 3//m purge flow. These results will provide guidance for the operation of the purged pitot tube in the CFSF. A simple mathematical model was proposed to estimate the solids circulation rate induced by a bubbling jet. Certain parameters in the model will require verification from cold flow experiments designed for this purpose. Two series of experiments were completed to investigate the motion of solid particles in the gasifier. The rate of particle mixing was studied as a function of the jet injection velocity.
