Computational modelling of particle degradation in dilute phase pneumatic conveyors

The aim of this paper is to develop a mathematical model with the ability to predict particle degradation during dilute phase pneumatic conveying. A numerical procedure, based on a matrix representation of degradation processes, is presented to determine the particle impact degradation propensity from a small number of particle single impact tests carried out in a new designed laboratory scale degradation tester. A complete model of particle degradation during dilute phase pneumatic conveying is then described, where the calculation of degradation propensity is coupled with a flow model of the solids and gas phases in the pipeline. Numerical results are presented for degradation of granulated sugar in an industrial scale pneumatic conveyor.

The valuation of property investments

In the seventh edition, the book has been updated and revised to reflect changes in the market, the development of appraisal methods and the subsequent changes in professional practice. The intial overview in Part I of the book, The Economic and Legal Framework, has been revisd to show the present position. Changes in appraisal techniques based on the research of the authors have been incorporated in Part II on Investment Valuation. Revisions have also been made in part II, again based on the research activities of the authors, which examines Investment Appraisal.The serves a number of purposes. First, it provides a critical examination of valuation techniques, with particular reference to the investment method of valuation. Second, it supplies practising valuers and appraisers with more effective data, information and techniques to enable them to carry out their valuations, appraisals and negotiations in an increasily competitive field. Finally, it provides assistance to students and academics in understanding the context of and a range of approaches to the valuation and appraisal of property investments. This book has been a key text in property investment appraisal for more than 30 years, it has sold many thousands of copies globally to academics, students and practitioners.
