Heat Convection
Professor Jiji’s broad teaching experience lead him to select the topics for this book to provide a firm foundation for convection heat transfer with emphasis on fundamentals, physical phenomena, and mathematical modelling of a wide range of engineering applications. Reflecting recent developments, this textbook is the first to include an introduction to the challenging topic of microchannels. The strong pedagogic potential of Heat Convection is enhanced by the following ancillary materials: (1) Power Point lectures, (2) Problem Solutions, (3) Homework Facilitator, and, (4) Summary of Sections and Chapters. .

Chemiluminescence from singlet oxygen under laminar flow condition in a micro-channel [An article from: Analytica Chimica Acta]
This digital document is a journal article from Analytica Chimica Acta, published by Elsevier in 2006. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: Singlet oxygen was generated by reaction of sodium hypochlorite and hydrogen peroxide in a micro-channel. The two reagent solutions were delivered into the micro-channel by syringe pumps, providing a laminar flow. Such a laminar flow forms a liquid-liquid interface instantly in a micro-channel, and then the interface collapses gradually through molecular diffusion with the residence times. The chemiluminescence from the singlet oxygen was emitted in the course of the collapse of the interface under laminar flow condition. The chemiluminescence intensity was observed continuously and stably in the micro-channel as long as the reagents were fed into the channel. We examined the features of the chemiluminescence emitted in the micro-channel by changing the flow rates of reagents and the detection points in the micro-channel. The data obtained were considered along with the residence times and diffusion lengths. We also examined the effects of antioxidants, such as sodium azide, histidine, nitroblue tetrazolium, and 2-propanol on the chemiluminescence intensity. .

Motion of micro-particles in channel flow [An article from: Atmospheric Environment]
This digital document is a journal article from Atmospheric Environment, published by Elsevier in 2004. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: The motion of micro-particles in channel flow was investigated using the DNS method for Re=3300 (based on center velocity and half channel width). The calculations used the fractional projection method to directly solve the Navier-Stokes equations, and the explicit third-order Runge-Kutta method for the time integration. A higher order finite difference scheme was used to discretize the fluid dynamics equations. The numerical results provided the two-phase flow field in the near-wall region with micro-particles. The simulation results showed that particles with Stokes number on the order of 0.1 tend to congregate near the wall while the micro-particles 1@mm in diameter distribute homogeneously in the whole flow field. Simulations of micro-particulate matter movement using the @k-@e turbulence model applied to the same problem as the DNS analysis showed that the turbulence model could not accurately predict the micro-particle motion in the turbulent flow near the wall, with higher particle concentrations close to the centerline and lower concentrations near the wall. .

Fluid Flow, Heat Transfer and Boiling in Micro-Channels (Heat and Mass Transfer)
The book treats the problem of single- and two-phase heat transfer in micro-channels We consider the effect of wall roughness on energy dissipation, axial heat conduction, operating parameters corresponding to stable and unstable flow and steady and unsteady flow with distinct interface. In the book we use our own results on a number of problems related to flow and heat transfer, as well as those of numerous theoretical and experimental investigations published in current literature. The presented materials are easily comprehensible to engineers and engineering students with some graduate-level familiarity of fluid mechanics and the theory of heat transfer. .

Hydrogen production for fuel cell application in an autothermal micro-channel reactor [An article from: Chemical Engineering Journal]
This digital document is a journal article from Chemical Engineering Journal, published by Elsevier in 2004. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: Results concerning the coupling of the steam reforming (SR) and total oxidation (TOX) of methanol in a two-passage reactor are presented. A commercially available copper based catalyst is used for the steam reforming. For the total oxidation, a highly active cobalt oxide catalyst was developed. Both catalysts are used in form of thin layers immobilized on the wall of the micro-channels. Reactor design and operating conditions are based on kinetic models developed under isothermal conditions in micro-structured reactors. For the oxidation reaction, complete conversion of methanol (>99%) at temperatures higher than 250^oC is observed. For the steam reforming, the hydrogen and CO"2 selectivity is higher than 96% for methanol conversion up to 90%. Besides the steady state, the dynamic behavior of the coupled system is studied. It is shown that the transient behavior is mainly determined by the thermal inertia of the system. .
