Abstract
The Serpens ("triple source") radio continuum jet shows a series of
aligned knots with ![[FORMULA]](img1.gif)
-2" angular
separations, forming a curved structure circumscribed within a cone of
![[FORMULA]](img2.gif)
full opening angle. We present a high
resolution, 3D numerical simulation of a jet with variable ejection
direction and velocity with parameters appropriate for the Serpens
jet, from which we obtain predictions of 3.6 cm radio continuum
maps. We find that the general morphology of the radio emission, and
the time evolution of the successive knots, qualitatively agree with
3.6 cm VLA observations of the Serpens radio jet.
