| Title: | LOCO - a linearised model for analysing the onset of coolant oscillations and frequency response of boiling channels. |
| Authors: | Romberg, TM |
| Issue Date: | Dec-1982 |
| Publisher: | Australian Nuclear Science and Technology Organisation |
| Abstract: | Industrial plant such as heat exchangers and nuclear and conventional boilers are prone to coolant flow oscillations which may not be detected. In this report a hydrodynamic model is formulated in which the one-dimensional non-linear partial differential equations for the conservation of mass energy and momentum are perturbed with respect to time linearised and Laplace-transformed into the s-domain for frequency response analysis. A computer program has been developed to integrate numerically the resulting non-linear ordinary differential equations by finite difference methods. A sample problem demonstrates how the computer code is used to analyse the frequency response and flow stability characteristics of a heated channel. |
