Angular momentum flux and angular momentum () around the disk region (color streamlines in the gray image, in SI units), for R_ℓ14 (left) and R_40ky_ℓ18 (right) at 103 kyr. All quantities are azimuthally averaged and averaged between the upper and lower planes. From top to bottom: Laminar transport (), turbulent transport (), magnetic transport (), and their sum. White curves outline the disk scale height H. The laminar flow convects mass with positive angular momentum, while the tensor terms (Reynolds and Maxwell) transport the angular momentum outward. In particular, the magnetic tensor dominates in the envelope, and this allows the mass to fall onto the disk through the loss of angular momentum. The general pattern persists with improved resolution. White patches in the gray image are due to locally negative angular momentum. This is an artifact of the averaging because the selected axis is not exactly aligned with the asymmetric outflow.
