Analytical and experimental investigation of the rewetting of circular channels with internal V-grooves

Optimizing the design of receiver in parabolic trough by using genetic algorithm

“…Liquid front velocity is applied without heat flux [13]. The adiabatic model (without heat flux) considers an open microchannel with the liquid layer as its control volume and the balance of forces as its momentum equation.…”

“…Next, predicting the maximum external heat flux in an open-grooved micro-channel of the heat pipe can withstand and maintain efficient heat transfer. Liquid front velocity was considered without heat flux (an adiabatic model) on the basis of the approach of Peterson [13]. A horizontal pipe with microgrooves etched in its inner surface is studied by using a stratified two-phase flow, as shown in Fig.…”

“…However, limited studies have focused on integrating the capillary system into the absorber receiver of a parabolic trough, a device that could enhance heat exchange in solar energy power plants. Peterson [13] initiated the study of micro-grooved heat exchanger. However, Peterson generated a model with internal V-grooves and without other types of grooves, such as semicircular groove.…”

Geometric optimization for a thermal microfluidic chip

“…Peterson et al [34] considered the rewetting characteristics of capillary induced liquid flow in circular channels with small circumferential grooves machined on the inner surface. Schneider et al [35] studied interconnected mini heat pipe arrays for micro electronic cooling.…”

“…There are various investigations in the literature that considered a given geometry and studied the thermal characteristics of that given configuration of microfluidic chip [36], [34]. However, few researchers addressed the effect of geometric parameters on the different characteristics of microfluidic chips.…”
