Abstract
The onset and oscillatory instabilities of natural convection flows in a single-phase rectangular closed-loop thermosyphon are investigated using the one-dimensional model. In this study the axial conduction term in the energy equation is included and it is found that the effect of axial conduction stabilizes the thermosyphon systems. The critical Grashof number of onset and oscillatory instabilities are found to increase with increasing the values of shape ratio. The range of the Grashof numbers evaluated from this study can provide essential information on the various parameters for the design of a thermosyphon system.
