The model factored in several details of the overall quasi-cyclic process but approximated those at the scale of individual drops. In the last five years, drop level dynamics over hydrophobic surfaces have been extensively studied. These results can now be incorporated in the dropwise condensation model. Dropwise condensation is an efficient route to heat transfer and is often encountered in major power generation applications. Drops are also formed during condensation in distillation devices that work with diverse fluids ranging from water to liquid metals. Design of such equipment requires careful understanding of the condensation cycle,starting from the birth of nuclei, followed by molecular clusters, direct growth of droplets, their coalescence, all the way to instability and fall-off of condensed drops. The model described here considers these individual steps of the condensation cycle. Additional discussions include drop shape determination under static conditions, a fundamental study of drop spreading in sessile and pendant configurations, and the details of the drop coalescence phenomena. These are subsequently incorporated in the condensation model and their consequences are examined. As the mathematical model is spread over multiple scales of length and time, a parallelization approach to simulation is presented. Special topics include three-phase contact line modeling, surface preparation techniques, fundamentals of evaporation and evaporation rates of a single liquid drop, and measurement of heat transfer coefficient during large-scale condensation of water vapor. We hope that this significantly expanded text meets the expectations of design engineers, analysts, and researchers working in areas related to phase-change phenomena and heat transfer. 410 0$aMechanical Engineering Series,$x2192-063X 606 $aThermodynamics 606 $aHeat engineering 606 $aHeat$xTransmission 606 $aMass transfer 606 $aFluid mechanics 606 $aSurfaces (Physics) 606 $aQuantum statistics 606 $aEngineering Thermodynamics, Heat and Mass Transfer 606 $aThermodynamics 606 $aEngineering Fluid Dynamics 606 $aSurface and Interface and Thin Film 606 $aQuantum Gases and Condensates 615 0$aThermodynamics. 615 0$aHeat engineering. 615 0$aHeat$xTransmission. 615 0$aMass transfer. 615 0$aFluid mechanics. 615 0$aSurfaces (Physics) 615 0$aQuantum statistics. 615 14$aEngineering Thermodynamics, Heat and Mass Transfer. 615 24$aThermodynamics. 615 24$aEngineering Fluid Dynamics. 615 24$aSurface and Interface and Thin Film. 615 24$aQuantum Gases and Condensates. 676 $a536.44 700 $aKhandekar$b Sameer$0873964 702 $aMuralidhar$b Krishnamurthy 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910418326803321 996 $aDrop dynamics and dropwise condensation on textured surfaces$92519365 997 $aUNINA
