The book reports a part of results of a long term experimental project devoted to investigating single-phase flow pressure drop and heat transfer, flow boiling pressure drop and heat transfer, flow boiling instability and flow visualization of de-ionized water flow in microchannels. However, the main focus in this book is to present experimental results for single-phase flow and heat transfer characteristics in rectangular microchannels.The authors is encouraged to write this book because of noticed discrepancies between published results and conventional theory. The single-phase fluid flow results showed that no deviation of friction factors was found from the three different hydraulic diameters. The effect of fluid temperature on friction factor was insignificant and the friction factors themselves were in reasonable agreement with the developing flow theory. The single-phase heat transfer results demonstrated that smaller test sections result in higher heat transfer coefficients....
