We have begun a study of the relationships between dynamics and nonthermal emissions in radio galaxies. Here we report first results from 3D MHD simulations of jet-driven flows. Our calculations include for the first time in such studies explicit treatment of the acceleration and transport of the nonthermal electrons responsible for radio synchrotron emisssion and X-ray Compton emission. The particle transport includes diffusive acceleration at shocks within the flows, as well as synchrotron ``aging'' and second-order Fermi acceleration in smooth flows. From this we compute self-consistent emission properties. It is clear from this, for example, that the ``driven'' nature of jet flows makes equilibrium interpretations of emission features very unreliable. We will compare our first 3D results with previous axisymmetric computations. This work is supported at the University of Minnesota by the NSF and the Minnesota Supercomputing Institute and at Chungnam National University by KOSEF through the Korea-US Cooperative Science Program.
