As the isotope of helium-4, helium-3 is more and more attracted by scientists because of its special physical and chemical properties. And now, helium-3 is having many applications in the fields of cryogenic engineering, fundamental physics and space technology, etc. All these applications depend on the thermodynamic properties and transport properties. However, there is little experimental data of helium-3 and no uniform method to calculate its properties. This paper deals with the enthalpy entropy and transport properties of helium-3. The main research contents are as follows:1. Sufficient reference and different types of data have been collected into a searchable database, which is very necessary and convenient for the further research on helium-3.2. Calculation and prediction of the enthalpy and entropy of helium-3 are attempted by using the modified quantum version principle of corresponding states.3. Calculations of the thermal conductivities of helium-3 using the modified quantum version principle of corresponding states and the collision integrals model. It shows that there is a good result in a relative high temperature region using the modified quantum version principle of corresponding states.4. Prediction of the viscosity of helium-3 are presented by using the modified quantum version principle of corresponding states and some reasonable result have been obtained.
