A method for the measurement of thermal conductivity

In the longitudinal heat flow method for the measurement of thermal conductivity, the surface losses present a very serious source of error, specially at high temperatures. A mathematical procedure has been proposed to eliminate this source of error. It is shown that if the temperature is measured at three points instead of two as is usual, the surface losses can be accounted for.
