| Abstract: | Bifurcation theory in nonlinear dynamic systems and the principle of the determination of stability are presented in this paper. The paper then discusses the dissipative and nonlinear factors in thermal dynamic systems. A theoretical method for the study on flow instability is derived. To test the validity of the theoretical method in analysing two phase flow instability in the thermal dynamic systems, the experimental results on a natural circulation loop have been made use of. Comparison indicates reasonable agreement between theoretical predictions and the experimental results. |
