Experimental investigation on the thermo-hydrodynamics of oscillatory meniscus in a capillary tube using FC-72 as working fluid

- Oscillatory pattern of single meniscus in capillary tube for FC-72 is observed.
- At high evaporator temperature double peak in the pressure oscillation is noticed.
- Oscillation depends on the temperatures of reservoir, evaporator and condenser.
- Increase in evaporator temperature by 20 °C results in a pressure increase by 600%.
- There is a strong dependency of the thermal resistance on heat exchanger lengths.
