Theoretical Study of Two-Phase Flow Oscillation in a Hot Channel, (II)

The kinetic behavior of two-phase flow is considered by conventional linear control theory. This study considers only the essential factors so as to simplify the interpretation of the mechanisms involved in the observed phenomena. A change in heat flux due to a change in coolant velocity is taken into account to study the influence of heat transfer characteristics on the flow stability. While this influence has not appeared as clearly as in the previous numerical experiment⁽¹⁾, agreement was obtained with measurements reported from RWD RL.
