Abstract:	I present the results from my simulations of fluid instabilities inside supernovae with the multi-D radiation-hydrodynamic code, CASTRO. Massive stars are ten times more massive than Sun. Observational and theoretical studies suggest that these massive stars tend to end their lives with energetic explosions, so-called supernovae. Many fluid instabilities occur during the supernova explosions. The fluid instabilities can be driven by hydrodynamics, nuclear burning, or radiation. In this talk, I review the possible physics of fluid instabilities found in my supernovae simulations and discuss how the resulting mixing affects their observational signatures.
