Influence of pressure drops on the behavior of a single-phase natural circulation loop: Preliminary results1999 •
— In the present work, emphasis is on the analytical model to describe thermal hydraulic instabilities in heated channels. This includes linear mathematical stability analysis of density wave oscillation that often arises in the coolant channels used in nuclear reactors. The model considers conservation equations of mass, momentum and energy to describe coolant properties using homogenous equilibrium model. Weighted residual method is applied to those conservation equations to obtain corresponding simultaneous time dependent ordinary differential equations (ODEs). These coupled non-linear ODEs are used to describe the stability boundary given in terms of phase change number and subcooling number and other parameters.The first part of the work describes stability characteristics in a single heated channel by two phase flow modelling. Here a single heated channel is modelled in two different sections each for single-phase and two-phase, for a fixed external pressure drop. The stability map is obtained by using a constant inlet velocity of the coolant.In the second part, a two phase natural circulation open loop is modelled that only considers a basic loop system used in nuclear reactors such as Advanced Heavy Water Reactor (AHWR). The model geometry considers a rectangular loop having a heated channel along with a downcomer and a header.Finally the third part of the work includes analysis of a single phase natural circulation closed rectangular loop comprising of a heating section and an analogous cooling section. Unlike to previous sections, here the map is obtained for different aspect ratio of the loop.Apart from these, effect of various design parameters on stability map is also mentioned.
