摘要：

Fluid temperature measurements are reported for a natural convection loop operating in the steady state regime. Averaged and fluctuating measurements were made for a toroidal thermosyphon oriented in the vertical plane that was heated over the lower half and cooled over the upper half. The measurements were made along the tube diameter at the entrance and exit of the heating sections for heat inputs from 1400 to 8410 w/m**2. The amplitude of the temperature fluctuations exceeded 10 degree C near the inner walls indicating the effects from recirculating flow regions at the entrances to the heating and cooling sections.
