    33Am investigating the interaction between a cold clump in a supernovae remnant and a shock. To model this, am injecting a supersonic wind into the boundary, whose properties are specified by the jump conditions across an adiabatic shock. The jump conditions are calculated using the following parameters in the ambient medium:
    44
    5 || $T_{amb}$ || 10^4^ K ||
    6 ||$n_{amb}$ || 10^4^ cm^-3^ ||
    7 ||$v_{amb}$|| 0 ||
     5|| $T_{amb}$ || $10^4 ~K$ ||
     6||$n_{amb}$ || $10^4 ~cm^{-3}$ ||
     7||$v_{amb}$|| $0$ ||
    88
    99The sound speed of the ambient material for these parameters is (for $\gamma=5/3$):
    … …  
    1313which for a injected wind speed of $v_s=2,000 ~km/s$ gives a Mach number of:
    1414
    15 || $M$  || $200$ ||
     15|| $M_{wind}$  || $200$ ||
    1616
    1717The wind parameters are then given by the jump conditions for an adiabatic shock ($\gamma=5/3$):
    … …  
    2525The clump is initially in pressure equilibrium with the ambient medium, and its properties are given by:
    2626
    27 || $T_{clump}$ || 10^2^ K ||
    28 ||$n_{clump}$ || 10^6^ cm^-3^ ||
    29 ||$v_{clump}$|| 0 ||
     27|| $T_{clump}$ || $10^2 ~K$ ||
     28||$n_{clump}$ || $10^6 ~cm^{-3}$ ||
     29||$v_{clump}$|| $0$ ||
    3030
    3131

    33 The thermodynamics in the simulation are governed by an ideal EOS, and an adiabatic index of gamma = 5/3. The abundances are taken to be solar ($\mu=1.3$). Other parameters of interest are the clump radius, clump crushing time, sound crossing time (ambient and clump medium to travel a clump radius), wind crossing time (to travel clump radius):
