The objective of this investigation was to study the influence of ultrasound having a frequency of 20 kHz upon the heat conduction of three metals: steel, aluminum, and magnesium. The variables used in this study included: ultrasonic intensity and temperature. The temperature measurements were taken along the length of the rod with a radiation thermometer. A continuous heat transfer system, computer modeling program was used to determine the change in the heat conductivity coefficient due to the introduction of ultrasound into the metal. It was found that insonation of the metals increased the thermal conductivity from 2.25 to 3.55 times. For iron, the higher temperatures used decreased the influence of ultrasound. Aluminum showed the greatest temperature difference between the nodes and antinodes in the metal bar during insonation, a higher temperature being produced at the antinode.
