LECTURE 15
Ablative RT for large Froude numbers
RT stabilization by dynamics pressure (i.e. rocket effect)
From isothermal conditions (see previous slide)
In the ablative case the total pressure is static + dynamic P+ρU2=P+T T is the thrust In addition to the term [|P|] we need to determine [|T|] across the interface. The perturbation in thrust is given by [|T|]=-m[|vz|] = -m (vz
