Many AGN jets exhibit complex morphologies with S-, X- or Z symmetric structures. Such radio jets may initiate complicated cavity systems in the intracluster medium with S- or X-shaped orientations. In the last few decades observational and theoretical evidences have been mounting that the jets of such systems are precessing. However, the precession mechanism of AGN jets and their dynamical interaction with the ambient medium are not well understood yet. In this project we will focus on the study ofprecessing jets and their interaction with the cluster environment with a goal to understanding: 1) the role of jet precession on the jet or jet-lobe morphologies and the X-ray morphologies, 2) the role of jet precession on the onset of turbulence and 3) the particle acceleration due to internal shocks and turbulence. We will conductour study with the help of fully three dimensional relativistic hydrodynamic (RHD) and magneto-hydrodynamic (MHD) models employing publicly available codes. (AU)
