Experiment of Effect of Dissymmetry Throttling and Heating on Oscillation between Double Parallel Channels

The research of dissymmetric parameters are very useful to understand and eliminate the in-stability in parallel channels,and improve the stability of system.The experiment has been done in the ther-mohydraulics loop by double parallel round channels.With the inlet throttling or the degree of dissymmetry throttling increasing,the critical heating power of oscillation is increased,but the period of oscillation is not cillation is not affected,and the amplitude of oscillation is increased.The stability boundary of oscillation in double parallel channels has been finished,and the experimental correlation is obtained.affected,and nonlinear effects of amplitude of oscillation are observed experimentally.With the dissymmetry degree of heated power increasing,the critical heating power of oscillation is reduced,but the period of os-
