The effect on the flow caused by a thin rigid radial wall that acts as a total barrier to continuous zonal motion in a heated rotating annulus has been examined. The gross effects of increases in rotation on the flow in the absence of such a barrier are greatly diminished. Measurements of total heat transfer and temperature field are compared for the two cases.
Abstr-act -This paper briefly summarizes two decades of Space Systems Laboratory experimental research on large space structure assembly. Based on high fidelity neutral buoyancy simulation with direct correlation to space flight data, this research encompasses extravehicular activity (EVA), teleoperation and robotics, and cooperative EVA/robotic assembly activities. Results presented from the extensive data base indicate that humans are significantly more productive in EVA assembly than had been previously thought; that telerobotics have wide applicability in structural assembly tasks, and are nearing humans in performance for a selected subset of tasks; and that direct cooperation between EVA humans and robots in the assembly work site provides maximum performance and robustness to the large space structure scenario.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
