A Procedure for Application of the Three-Omega Method to Measurement of Gas Thermal Conductivity

A Procedure for Application of the Three-Omega Method to Measurement of Gas Thermal Conductivity

A non-linear least-squares curve-fitting procedure is proposed to analyze three-omega voltage data from a fine wire in a gas sample using the three-omega method. The method uses both three-omega components of the voltage arising from a sinusoidal heating current to determine the thermal conductivity...
