Abstract
Numerous stars exhibit large scale mass outflows of various forms. The mass outflows from YSO's in particular exhibit a bipolar outflow geometry. These YSO's are often surrounded by dense circumstellar disks, with bipolar outflows exiting from the rotation axis of the disk. The outflows consist of a narrow, well confined optical jet, which subsequently expands to form large scale cavities within the ISM. At the outflow boundary, material diff"uses into the flow, with a resultant exchange of momentum. The mass and momentum exchange that takes place at the outflow boundary occurs within a viscous boundary and a diffusion boundary.
