Some miscellaneous utilities

Liquid Fuel Thermal Database Calculate some properties of a few selected fuels at atmospheric pressure. Currently only 6. You can also calculate the boiling temperature at different pressures by numerically inverting the vapor pressure function.
Ethanol Property Calculator Calculate the thermodynamic properties of ethanol for arbitrary temperatures and pressures. The formulation is valid within 250-650 K and up to 280 MPa. Calculated properties are in general within 0.5%, except near the critical point.
A Simple EGR Calculator Calculate the in-cylinder properties based on a global lambda.
