Some preliminary results obtained during the operation of a high pressure, high temperature induction type heat exchanger capable of sustained operation are presented in graphical and tabulated form. The major components of the heat exchanger consist of a high pressure stainless steel chamber, water cooled induction coil, and graphite heater element. Nitrogen was used as the flow medium. The graphite surface temperature T, was measured for a number of mass flows with an optical pyrometer. The entrance temperature was found by keeping the gas from flowing through the hot graphite element and then measuring the exit gas temperature. The entrance temperature thus determined and the exit temperature with the hot graphite element in the heating cycle were than used to calculate the amount of energy absorbed as the gas passed through the graphite element.
