Type Ia Supernovae Theory

• Ra ~ 1025 (buoyancy to diffusion forces)

  • Nature of convection is not well known in this regime.

• Re ~ 1014 (inertial to viscous forces)

• Pr ~ 10-4 (momentum transport to heat conduction)

  • Viscosity effects are unimportant.

• Le ~ 107 (energy transport to mass transport)

  • Mass diffusion can be neglected.
  • Large departure from typical Le ~ 1 terristrial flames.
