 Q - shocked gas speed = shock speed?
+Q - does shock speed decrease with time?
+Q - should we get density enhancement with time along shock front?
+Q - how does cooling adjust shock profiles?
 The clump is initially in pressure equilibrium with the ambient medium, and its properties are given by:
 …
 The thermodynamics in the simulation are governed by an ideal EOS (specified by $\gamma$). The abundances are taken to be solar ($\mu=1.3$). Other parameters of interest are the clump radius ($R_c$), clump-ambient density contrast ($\chi$), clump crushing time ($t_{cc}=\sqrt{\chi} R_c/v_s$), sound crossing time (ambient and clump medium to travel a clump radius; $t_{sc}$), wind crossing time (to travel clump radius; $t_{wc}$):
 || $R_{c}$ || $10^{16} ~cm$ ||
 || ${\chi}$ || $10^{16} ~cm$ ||
 || $t_{cc}$ || $5\times 10^8~s$ ||
 || $t_{sc}$ (for ambient) || $5\times 10^8~s$ ||
 || $t_{sc}$ (for ) || $5\times 10^8~s$ ||
 || $t_{wc}$ (for domain of $L=10~R_c$) || $5\times 10^8~s$ ||
+|| ${\chi}$ || $100$ ||
+|| $t_{cc}$ || $10^{11}~s$ ||
+|| $t_{sc}$ (ambient medium) || $5\times 10^8~s$ ||
+|| $t_{sc}$ (clump medium) || $5\times 10^8~s$ ||
+|| $t_{wc}$ || $10^{10}~s$ ||
 The domain dimensions, simulation time & framerate, are given by:
