ShareA CORRELATION OF THERMAL CONDUCTIVITY DATA FOR HELIUM.
Author(s) : HANDS B. A., ARP V. D.
Type of article: Article
Summary
A CORRELATION FOR THE THERMAL CONDUCTIVITY OF HELIUM HAS BEEN DEVELOPED WHICH COVERS THE TEMPERATURE RANGE FROM TEMPERATURES JUST ABOVE THE LAMBDA LINE TO 830 K, AND DENSITIES UP TO ABOUT 160 KG/M3. THE DATA USED INCORPORATE SOME RECENT EXPERIMENTAL RESULTS WHICH COVER THE TEMPERATURE RANGE FROM 4 TO 20 K INCLUDING THE CRITICAL REGION. THE CORRELATION GIVES AN EQUATION WHICH GENERALLY FITS THE EXPERIMENTAL DATA WITHIN ABOUT 5%. HOWEVER, AT LOW TEMPERATURE, THE EXPERIMENTAL DATA DEVIATE UP TO ABOUT 10% FROM PREDICTIONS BASED UPON VISCOSITY MEASUREMENTS OR MOLECULAR DYNAMICS CALCULATIONS.
