Book Description
Turbulent Mixing and Chemical Reactions Jerzy Ba???dyga, Warsaw University of Technology, Poland John R. Bourne, Visiting Professor, University of Birmingham, UK and Emeritus Professor, ETH Zurich, Switzerland The way in which reagents are mixed can greatly influence the yield and range of products formed by fast, multiple chemical reactions. Understanding this phenomenon enables chemists to carry out reactions more selectively, make better use of raw materials and simplify product workup and separation. Turbulent Mixing and Chemical Reactions presents a balanced treatment of the connection between mixing and reaction. It contains theoretical aspects, experimental methods and expected results as well as worked examples to illustrate problem solving. This book will be of interest to all scientists involved in chemical engineering, physical chemistry, and synthetic chemists in the fine chemical and pharmaceuticals industry.

Book Description
Jet stirred reactors (JSRs) are frequently employed for studying homogeneous gas phase chemical kinetics of fuels. The most challenging aspect of JSR is the achievement of sufficiently rapid mixing by turbulent jets so that the temperature and concentration fields inside the reactor could be considered homogeneous. However, there has not been any investigation in the literature which conclusively addresses that rapid mixing is indeed achieved. In this work, computational fluid dynamics (CFD) simulations for JSRs are conducted to gain insights into the dynamics of jet mixing. CFD simulations are conducted for some of the geometries commonly used by researchers and mixing inside the reactor is visualized by computationally tracking an inert tracer pulse. Results suggest that some of the commonly used reactors could have significant concentration non-homogeneity and therefore may not be suitable for chemical kinetic studies. For conditions when the flow in the reactor is sufficiently turbulent and recycling rate is high, back mixing can become problematic even though the concentration field is more or less homogeneous. As a consequence, the vast chemical kinetic data obtained from such facilities is questionable. Furthermore, modifications to the design of JSR are considered that could significantly improve concentration homogeneity. An alternative geometry of the reactor is evaluated and shown to be promising. A new JSR is designed and fabricated for studying homogeneous gas phase chemical kinetics over a range of pressures from atmospheric to elevated (up to 50 bar).
