Separation of liquid-vapor two-phase flow in headers of microchannel condensers
… of liquid and vapor as a way to improve condenser efficiency and heat transfer performance of typically microchannel design. This thesis is composed of three parts in the following order. 1. Separation of vapor and liquid in condensers is evaluated via numerical study as a way to improve …

Potentials for COP increase in vapor compression systems
… compression systems: work recovery ejectors, condenser subcooling and increase of relative size of heat exchangers (HXs). Regarding work recovery ejectors, experimental results showed that the COP of the ejector system increased between 8.2% and 14.8% when compared to a conventional expansion …

Experimental study and modeling of liquid-vapor flow in the second header of microchannel condensers with separation circuitry
… a condensation process, liquid on the wall of a condenser creates an extra thermal resistance thus is detrimental to heat transfer. Separating the condensate from vapor is one of the ways to improve heat transfer and reduce pressure drop. This work presents an experimental and numerical study of …
