The theme of the research concerns the dynamics of natural circulation loops with distributed heat sources. The dynamic behaviour of this kind of systems is investigated by means of both theoretical (1D/3D modal and non-modal methods) and experimental (ad hoc testing facility) approaches. The study attempts to provide a first systematic analysis of the dynamics of free convection in presence of distributed heating. Attention is paid to the prediction of stable and unstable (oscillating) flow regimes, whose occurrence is determined by several factors (e.g., geometry, heat-exchange features, piping material, and kind of heat source).
