  Assuming Newton's law of cooling, the propagation and structure of isothermal
acoustic shocks are studied under four different viscosity laws. Employing both
analytical and numerical methods, 1D traveling wave solutions for the velocity
and density fields are derived and analyzed. For each viscosity law considered,
expressions for both the shock thickness and the asymmetry metric are
determined. And, to ensure that isothermal flow is achievable, upper bounds on
the associated Mach number values are derived/computed using the isothermal
version of the energy equation.
