Thermosiphon with vapor separation: Experimental comparison to conventional type

The system with separation showed improved operation in startup. The conventional system took longer time to stabilize with stronger oscillations of mass flow rate at startup than system with separation. The temperature difference of the system with separation also had a small improvement when heat load was low in steady state. Oversized condenser is identified as the reason why separation did not always realized full potential to improve the performance of the system in steady state. Reducing size of the condenser is identified and the right action and it will be verified in a next step.
