| 35 | | In this picture, the radial expansion of the flow drags the field lines out of the collision region. Depending on which side of the interface you are on, this is either enhanced by the shear, or partially cancelled out (can see this in the streamline plots). On the side where the field remains relatively straight, gas doesn't get deflected as strongly as on the other side, given the flow is tied to the field. (Here, could strengthen this argument by better understanding of the connection between field, velocity, in MHD shocks). This leads to more net x momentum on one side of the interface then the other, and thus, torque. A figure shows this to be the case. However, whether this picture for why the momentum gets amplified on one side of the interface is correct, is still unclear. Furthermore, I can't find evidence for this visually in Visit. |
