Abstract
The experimental study on the heat transfer in circular tube under oscillatory flow conditions was conducted. The sinusoidal fluid oscillations under 0.1~1 Hz were made by the oscillator in the text loop to analyze the effect of flow instability on two-phase flow boiling heat transfer. The traces of inlet oscillatory flow in 0.4 and 1.37 MPa and traces under Frequency Modulation Conditions were analyzed, respectively. The oscillations of Wall Temperature and Outlet Temperature were obtained. And, the oscillation of Outlet Temperature which was lag phase about 1/4 cycle, and oscillations of Wall Temperature were with same frequency.
