Analytical description of chaotic oscillations in a toroidal thermosyphon [PDF]
, 1995 Multiple time scales and singular perturbation techniques are used to describe the ordinary and the chaotic oscillations due to natural convection in a fluid loop subject to a known external heat flux. The turbulent flow in the loop is modelled using the

Flow instabilities in a horizontal thermosyphon reboiler loop [PDF]
Experimental Thermal and Fluid Science, 2016 Thermosyphon systems have been the subject of several studies due to instability issues negating their attractive high heat fluxes, low temperature gradients requirement, reduced weight and simple, pump-less system. There is a dearth of design data for horizontal thermosyphons hence the transient behaviour of a horizontal thermosyphon reboiler loop has
