摘要：
The inclined granular flow offers the explanations for many phenomenon and is a potential choice as a high-power spallation target. Here we studied about the stability of the inclined granular flows down rough bottoms. Following the previous work, we mainly studied about the influence of inclined angles on the stability of flows. There are some conclusions of this work: (1) the flows with various inclination angles can be divided into five regions. (2) The oscillation flow region can be further divided into three sub-regions according to the oscillation modes. (3) Bagnold profile is valid in disordered flows but not in ordered flows. In ordered flows, there are local maximum values in shear rate profiles. (4) The oscillation flow region is a transition region between ordered and disordered flow region, where the self-organization and dilatant are shown more clearly.
