modelidealGasLimit
Information
This model is used to validate the behavior of the EoS in the ideal gas limit, that is at lim d → 0 .
How to use:
- Simulate with any
T_trip < T < T_max - Plot
f.rdandB - Make
dthe independent variable of the plot - Set the horizontal axis
(d)to logarithmic scale - Set line style to dotted and marker style to cross
- Look at the graphs
