“…However, due to thermal conduction in the microchannel substrate, this inevitably results in some degree of circumferential non-uniform heat flux on the internal wetted surface. Studies have been conducted on the influence of parameters such as the number of channels [6,7], the cross-sectional profile [8][9][10], hydraulic diameters [11][12][13][14][15], systems with uniform heating [16][17][18][19][20][21][22], the orientation of the channel [1,23,24], hydrodynamic effects like confinement [25][26][27] and the effect of varying working fluids [28,29].…”
