A methanol model was previously implemented in the Cheetah code. The model is based on a combination of shock Hugoniot data and sound speeds determined via ISLS. High-pressure and temperature equation of state data on pure ethanol was not available, so Impulsive Stimulated Light Scattering measurements were made of the sound speed of ethanol at 250° C. Results are shown in Figure 5. A Cheetah exponential-6 potential model was fit to the ISLS measurements. The 3% difference between data sets shows the utility of Cheetah and the consistency between static and dynamic equation of state measurements. High precision ISLS measurements easily resolve ethanol velocities from 2-3% lower methanol velocities.
