| Abstract: | This paper presented a study of flowability of the inclined dense granular-flow target for a neutron irradiation facility, which is capable of providing high-energy neutrons suitable to advance fusion reactor material research. The results from simulations and theoretical analysis described the constancy and stability of the flow, which was rarely mentioned before. It was found that 25° was acceptable for a steady and stable accelerating flow and all the results supported the availability of this granular flow for a potential choice of the heat medium. |
