Classical novae are excellent laboratories for studying many astrophysical
phenomena. They have complex structures due to interacting outflows. They
produce shocks where these outflows collide. They have both thermal and
non-thermal emission. They evolve over long time scales and remain visible
at radio wavelengths for two to three years. The Next Generation Very
Large Array (ngVLA) will provide unprecedented opportunities to study these
complicated eruptions. The ultra-sensitive imaging capabilities for both
thermal and non-thermal emission will enable us to trace the expansion of
the ejecta and monitor the interactions between the outflows with
milliarcsecond resolution. We will demonstrate the exciting capabilities
of the ngVLA with simulated images of classical novae at multiple stages of
their evolution.
