Abstract
Parallel-channel two-phase flow systems with ocean conditions suffer from very serious parallel instability, depending on the inherent characteristic of each channel and operating conditions. The influences of ocean conditions on the instability of parallel channel are very intensive. The trajectories of mass flow are very complex, sometimes even chaos occurs. In this paper, Fast Fourier Transformation (FFT) method is used to analyze the curve of mass flow. Based on this method a complex oscillation curve can be decomposed. Some basic motion and inherent characteristics can be shown by the decomposition. The onset of inherent parallel instability is also analyzed.
