The data presented in the previous chapters, as well as the data from investigations of single-phase forced convection heat transfer in micro-channels (e.g., Bailey et al. 1995 Guo and Li 2002, 2003 Celata et al. 2004) show that there exist a number of principal problems related to micro-channel flows. Among them there are (1) the dependence of pressure drop on Reynolds number, (2) value of the Poiseuille number and its consistency with prediction of conventional theory, and (3) the value of the critical Reynolds number and its dependence on roughness, fluid properties, etc. 

Adams et al. (1998) investigated turbulent, single-phase forced convection of water in circular micro-channels with diameters of 0.76 and 1.09 mm. The Nusselt numbers determined experimentally were higher than those predicted by traditional Nusselt number correlations such as the Gnielinski correlation (1976). The data suggest that the extent of enhancement (deviation) increases as the channel diameter decreases. Owhaib and Palm (2004) investigated the heat transfer characteristics...

SINGLE-PHASE FORCED CONVECTION IN MICROCHANNELS A State-of-the-Art Review... 

Following the recent developments in microfabrication, a number of major research initiatives have been launched to improve our understanding of the heat transfer and fluid flow phenomena at the micro level. A survey of the literature presented below gives a brief summary of the research carried out in single-phase forced convection in microchannels mostly in the last 15-20 years.

Correlations for single-phase forced convection in the laminar regime have not been reported for the parameters obtained locally and along the flow.

The scientific program starts with an introduction and the state-of-the-art review of single-phase forced convection in microchannels. The effects of Brinkman number and Knudsen numbers on heat transfer coefficient is discussed together with flow regimes in microchannel single-phase gaseous fluid flow and flow regimes based on the Knudsen number. In some applications, transient forced convection in microchannels is important. 

The convective boiling coefficient can be estimated using the equations for single-phase forced-convection heat transfer modified by a factor to account for the effects of two-phase flow ...

Single-phase forced convection through microchaimels can be studied by determining the velocity distribution and the temperature field in the fluid region with the aid of the mass conservation principle continuity equation), the fluid momentum balance equations, and the energy balance equation [1] ... 

Heat transfer to a digitized flow in a microchannel is similar in many ways to single-phase forced convection in microchannels. The thermal boundary conditions that exist are the same however, due to the unique rolling-type flow, DHT behaves in a significantly different fashion. In Fig. 3, the temperature field shows that heat is convected by the vortices and circulates within the droplet. As a droplet rolls down a heated microchannel, cool fluid from the center of the droplet is continually transported to the outer edges of the droplet while hot fluid at the wall is convected inward. Heat gradually diffuses...
