As a real-world introduction to the modeling of chemical kinetics and reactor design, the author includes a case study on ammonia synthesis that is integrated throughout the text. The text also features an accompanying CD, which contains computer programs developed to solve modeling problems using numerical Edition: 1. The core configuration of AECL three dimensional kinetics benchmark problem in a heavy water reactor has been considered for validation. The core geometry is shown in Fig 1. Only the inner and outer core region was modelled excluding the reflector region File Size: KB.

This text combines a description of the origin and use of fundamental chemical kinetics through an assessment of realistic reactor problems with an expanded discussion of kinetics and its relation to chemical thermodynamics. It provides exercises, open-ended situations drawing on creative thinking, and worked-out examples. A solutions manual is also . The method of Taylor series expansion is used to develop a numerical solution to the reactor point kinetics equations. It is shown that taking a first order expansion of the neutron density and precursor concentrations at each time step gives results that are comparable to those obtained using other popular and more complicated methods.
