The Non-Inertive-Feedback Thermofluidic Engine (NIFTE) is a device capable of utilising low-grade heat to produce pumping work. An investigation on the applicability of different working fluids for the NIFTE is presented, with emphasis on the effects of key thermodynamic properties of the...

A two-phase thermofluidic oscillator was recently reported as being capable of undergoing sustained operation when a constant and low temperature difference is applied to the device, which consists of a network of tubes, compartments and two heat exchanger blocks. Within this arrangement a...

A simple approach is presented for the modeling of complex oscillatory thermal-fluid systems capable of converting low grade heat into useful work. This approach is applied to the NIFTE, a novel low temperature difference heat utilization technology currently under development. Starting from a...
