Free Convection Film Flows and Heat Transfer

This book presents recent developments in our systematic studies of hydrodynamics and heat and mass transfer in laminar free convection, accelerating film boiling and condensation of Newtonian fluids, as well as accelerating film flow of non-Newtonian power-law fluids (FFNF). These new developments provided in this book are (i) novel system of analysis models based on the developed New Similarity Analysis Method; (ii) a system of advanced methods for treatment of gas temperature- dependent physical properties, and liquid temperature- dependent physical properties; (iii) the organically combined models of the governing mathematical models with those on treatment model of variable physical properties; (iv) rigorous approach of overcoming a challenge on accurate solution of three-point boundary value problem related to two-phase film boiling and condensation; and (v) A pseudo-similarity method of dealing with thermal boundary layer of FFNF for greatly simplifies the heat-transfer analysis and numerical calculation. A system of practical application equations on heat and mass transfer are provided in each chapter, which are formulated based on the rigorous numerical solutions with consideration of variable physical properties. In addition, in the second edition, other new research developments are further included on resolving an even big challenge associated with investigations of laminar free film condensation of vapour-gas mixture. They involve the novel methods for treatment of concentration- and temperature- dependent physical properties of vapour-gas mixture, and for rigorous solution of interfacial vapour saturation temperature, which have lead to rigorous analysis and calculation results on two-phase film flow velocity, temperature, and concentration fields, as well as condensate heat and mass transfer.

  De-Yi Shang

Dr. De-yi Shang got his Ph.D degree from Tsinghua University, China, worked at six universities in China, Europe and North America as professor and research scientist. In his early years, he carried out the research of radiation heat transfer with contributions on development of partial successive division method for evaluation of complicated radiation exchange factors in enclosure with non-isothermal medium and international journal papers in different countries. Since 1988, he has investigated heat transfer with fluid convection without and with phase change for consideration of coupled effect of variable physical properties. The contributions in his number of publications in some authority and distinguished journals were applied with over 100 citations. In 1996, he was awarded very prestigious research scientist from Norwegian Research Council designed for outstanding foreign scientist with proven international reputations. In 1999, he was included in Who’s Who in the World, USA, as an eminent scientist.  In 2006 and 2010, he published his monographs “Free convection film flows and heat transfer” and “Theory of heat transfer with forced convection film flows ” respectively in Springer-Verlag, for reporting his advanced theory, models and rigorous research results on laminar free and forced convections respectively with phase change for consideration of coupled effect of variable physical properties. In 2011, his biographical sketch was included in Who’s Who in Thermal Fluids (www.thermalfluidscentral.org/who).
