This book was released on 2015-07-14 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical Prediction of Flow, Heat Transfer, Turbulence and Combustion: Selected Works of Professor D. Brian Spalding focuses on the many contributions of Professor Spalding on thermodynamics. This compilation of his works is done to honor the professor on the occasion of his 60th birthday. Relatively, the works contained in this book are selected to highlight the genius of Professor Spalding in this field of interest. The book presents various research on combustion, heat transfer, turbulence, and flows. His thinking on separated flows paved the way for the multi-dimensional modeling of turbulence. Arguments on the universality of the models of turbulence and the problems that are associated with combustion engineering are clarified. The text notes the importance of combustion science as well as the problems associated with it. Mathematical computations are also presented in determining turbulent flows in different environments, including on curved pipes, curved ducts, and rotating ducts. These calculations are presented to further strengthen the claims of Professor Spalding in this discipline. The book is a great find for those who are interested in studying thermodynamics.

Available in PDF, EPUB and Kindle. Book excerpt: An analysis of combined heat and mass transfer from a flat plate has been made in terms of Prandtl's simpified physical concept of the turbulent boundary layer. The results of the analysis show that tor conditioins of reasonably small heat and mass transfer, the ratio of the mass- and heat-transfer coefficients is dependent on the Reynolds number of the boundary layer, the Prandtl number of the medium of diffusion, and the Schmidt number of the diffusing fluid in the medium of diffusion. For the particular case of water evaporating into air, the ratio of mass-transfer coefficient to heat-transfer coefficient is found to be slightly greater than unity.

Available in PDF, EPUB and Kindle. Book excerpt: A predictive model is described to simulate the aqueous CO2 corrosion of iron in turbulent pipe flow. Mass transfer is modelled with a two dimensional low Reynolds number k- 3 turbulence model by simultaneously solving the conservation equations for mass, momentum, kinetic energy of turbulence and its dissipation rate, along with the concentrations of various dissolved species. The effect of the slow homogeneous chemical reaction Of CO2 hydration is incorporated into the model by including an extra source term in the transport equation for carbonic acid. Other homogeneous chemical reactions are assumed to be in equilibrium. The electrochemical reactions considered are iron dissolution and the reduction of H2CO3, H+ and H 2O. An iterative procedure is employed to calculate CO2 corrosion rates by ensuring the mixed potential theory is satisfied and the various surface chemical equilibria are preserved. It is shown that at a bulk PH 4 and very low flow velocities the reduction of H2CO3 is controlled by CO2 hydration. At higher velocities and in the high current density region where Tafel behavior is no longer observed, H2CO3 reduction is controlled by the interaction of chemical reaction (CO2 hydration) and mass transfer. The H+ reduction is more flow sensitive than the H2CO3 reduction. CO2 corrosion is more influenced by flow at PH 4 than at higher PH values. Generation of H 2CO3 by CO2 hydration enhances the H2CO 3 mass transport and reduces the H2CO3 mass transfer entrance length. The relative contributions of H2CO3, H+, find H2O reduction to the corrosion current depend on the solution PH. The CO2 corrosion rate is accelerated by turbulent flow and CO2 partial pressure through an approximate power law. Present model predictions were tested against experimental findings and other models. Good agreement is achieved. A simplified spreadsheet-based electrochemical model of CO2 corrosion is also developed. Overall mass transfer coefficients.

Development of a macrokinetics approach is generalized to the analysis of fast chemical reactions mainly based on an example of cationic isobutylene polymerization, which falls into to a new class of liquid-phase processes. The ways of decision of the hydrodynamical, thermal and kinetic movement’s equations of reaction mixture in which the fast exothermic chemical reaction runs are described.

This book was released on 2014-11-18 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the book is to provide basic idea on fluid dynamics and its related properties and help to understand research work in the field of transport phenomena in MHD flow. The fluid model describing various aspects of boundary layer flow past a vertical flat surface embedded in Darcian porous media have been studied. An asymptotic periodic transformation is used to solve the dynamical equations. The influence of several physical effects like thermal radiation, chemical reaction, magnetic field, radiation absorption,heat sink etc. have been considered on various fluid properties. In this study some significant engineering properties of interest such as skin-friction, Nusselt number and Sherwood number are also calculated and analyzed through graphs and tables. It is expected that, the governed exact closed form of solutions corresponding to different problems can be used for validating numerical treatment of certain critical flows with heat and mass transfer phenomena.
