Distribution of density and velocity field. In each panel, the left side presents a snapshot at 4.0t_B, while the right side displays the time-averaged distribution. Colors represent the density, measured in units of the density at the center of the initial torus. The streamlines reflect the velocity field on the poloidal plane. The black solid line marks the scale height of accretion flows. The scale height is defined as the height at which the density drops by a factor of e relative to the density at the equatorial plane. Panel (A): Run R22. Panel (B): Run R23. Panel (B): Run R24. Panel (D): Run N24.
