This
Review offers quantitative and qualitative analyses of various
compact and micro heat exchangers (C-MHXs) in terms of the friction
factor, Nusselt number, and heat transfer augmentation mechanism.
The C-MHXs, which have already been implemented in industry, are analyzed
along with brand-new heat transfer technologies. Pressure drop and
Nusselt number are used to characterize the performance of the heat
transfer technologies and specifically to ascertain their appropriateness
in analyzing C-MHXs. A precise analysis of the correlations reveals
that the design parameters must be carefully examined before selecting
a suitable correlation. In addition to the quantitative and qualitative
analyses, computational fluid dynamics analysis used to design the
C-MHXs is also compared with experimental analysis found in the literature.
This review of C-MHX technologies will hopefully encourage and motivate
more in-depth research into energy-efficient heat transfer devices.
