Özet:

 


This study presents a comprehensive
review on single and two-phase pressure drop characteristics and flow boiling
instabilities in microchannels to outline the discrepancies in the literature.
The effect of mass flux, heat flux, experimental conditions, channel
geometrical parameters (hydraulic diameter, aspect ratio etc.) was surveyed
critically over a broad range of literature studies including the past and
recent researches. Additionally, conventional and micro-scale pressure drop
correlations are discussed. This study showed that the continuum theory is
applicable for single-phase pressure drop applications with some
considerations. Also, the two-phase pressure drop in micro-scale was found to
have similar characteristics with conventional-scale channels. On the other
hand, flow boiling instability is one of the important issues in microchannel
heat exchangers. Flow boiling instabilities affect the system performance and
may cause system failures. Therefore, unstable
flow boiling conditions were identified in this paper for a reliable design of
micro heat exchangers.
