Description

<p>In parallel channel systems with multi-branches structure is anticipated peculiar behaviours in flow distribution and dynamic behaviour, i.e. oscillation mode. In this study, the influence of a parallel channel configuration on the stability of flow oscillations was investigated. An experiment was conducted with a single channel, two parallel channels (Single Unit) and two parallel units having two parallel channels in each, consequently four parallel channels (Parallel Units). The results show that similar phenomena were observed between the Single Unit and Parallel Units. Although Single Unit is slightly more stable than Parallel Units, the threshold of flow instability has been estimated by using a modified G.Guido’s method.</p>
