HIRB — The Centrifuge Facility at Clarkson
- 67 Downloads
The International Center for Gravity Materials Science and Applications at Clarkson University has constructed the only centrifuge facility in the world dedicated solely to materials processing research and related flow visualization. This centrifuge has been named “HIRB,” which is an acronym for “High Inertia Rotating Behemoth.” HIRB is a modified variable-speed boring mill with an arm radius of 1.524 m. The maximum attainable rotation rate is 90 rpm, which corresponds to a maximum acceleration of approximately 13.8 g (g = 9.81 m/s2). This paper will focus on the main characteristics of HIRB and its capabilities for gravity materials science experiments. Equipment used for gravity materials processing experiments on HIRB are described. A low cost, low weight and low power gradient freeze furnace was designed, constructed and tested on HIRB under high gravity conditions.
