“…In contrast side, (Kse1, and Kse2) indicate loss coefficients produced by a rapid expansion from a micro-channels to a subchannels and from a subchannels to manifolds, respectively. The values for coefficients of loss (Ksc1, Ksc2, Kse1, and Kse2) are respectively 0.5, 0.47, 0.72, and 0.81 [21]. So, the following equation may be used to calculate experimentation's fanning friction factor based on microchannel pressure drop [22]:…”

This study investigated the effects of electroplating coatings in a single microchannel on the flow and heat transfer parameters of single-phase flow was the focus of an experiment that was carried out recently. Experiments were carried out using the micro-channel has dimensions of 0.3 mm width, 0.7 mm depth, and 60 mm length and deionized water serving as a working fluid at the temperature for 30 degrees Celsius at the intake, with a range of Reynolds numbers spanning from 283 to 4840. The results of experiments and the calculations shown that the fanning friction factor correlation of laminar and turbulent flow can expect experimental findings with a high level of accuracy. Moreover, when the Reynolds number increases, the Nusselt number increases as well. There is improvement of heat transfer performance for Al2O3 coated and composite Graphene-Al2O3 coating through all Reynolds number. fanning friction factor for models with Al2O3 coated are a greater than conventional microchannel while and composite Graphene-Al2O3 coating more fanning friction factor than Al2O3 coated. The results demonstrated that a predictable correlation is appropriate to guess a friction factor of conventional microchannel, Al2O3 coated and composite Graphene-Al2O3.
