| An experimental investigation is performed to determine air side forced convective heat transfer and flow characteristics of wavy fin, serpentine, multi-port slab, crossflow microchannel heat exchanger.;Experiments are conducted for 30 different operating conditions in single-phase air-to-ethylene glycol crossflow configuration. These operating conditions (752 < Rea < 3165, and 23°C < Ta,i < 46.5°C) yield air side Nusselt number ( Nua), and Colburn factor (ja) of up to 8.4 and 0.009 respectively. The Nua and ja obtained in these experiments are generally higher, and friction factor, fa is generally lower than those found in the literature. Possible explanations for the apparent discrepancies are explored.;A thorough uncertainty analysis is performed. Uncertainties in Nua, ja, and friction factor f a are approximately 4.8%, 5.2%, and 5.8% respectively. A large number of key heat exchanger performance parameters are also investigated in order to develop general correlations suitable for industrial applications and engineers. |
