Scaling Effects for Liquid Flows in Microchannels (2006, background): “” Guo and Li [3] remarked that because different forces have different dependences on the characteristic length, the surface forces, like the surface tensions, viscous forces, or electrostatic forces, become more important and even dominant as the scale is reduced.”
History, Advances, and Challenges in Liquid Flow and Flow Boiling Heat Transfer in Microchannels: A Critical Review (2012, background): “fundamental understanding of the fluid flow and heat transfer phenomena, and a recognition of need for further heat transfer enhancement [40-47].”
Single-phase heat transfer in microchannels The importance of scaling effects (2009, background): “In fact, Guo and Li [11] reported that in their experiments on flow resistance in a circular glass tube, they initially measured the diameter as 84.”
Experimental investigation into the pool boiling heat transfer of aqueous based γ-alumina nanofluids (2005, background): “The effect of the characteristic size of the system is expected to be important when the system is very small ( Guo & Li, 2003; Celata et al., 2004).”
