    The mechanics of fluid - particle systems: with special reference to agriculture
    Macmillan, R. H. (Ross Macmillan, 2007)
    This monograph and the associated computer program are concerned with the prediction of the trajectory of particles moving relative to fluids. The program is quite general and can be used to plot the trajectory of 'any' particle moving relative to 'any' fluid. However it cannot allow for particle spin or analyse three dimensional problems. The monograph, which assumes a 2nd year level of engineering science, is written particularly for professional agricultural engineering courses but may be of interest in the study of equivalent subjects for chemical or other engineers. It could also form the basis for short courses for practising engineers. The analysis is based on elementary fluid mechanics and provides the reader with a review of the basic theory and its application to the prediction of trajectory in one and two dimensions (Section I, Chapters 2 to 4). The latter develops the algorithms on which the associated computer program is based and presents a validation of the program based on published results. The major parts of the monograph illustrate the application of the program to a number of worked examples of interest in agriculture. Section II (Chapters 5 to 8) deals with examples of four distribution problems (ground and aerial based spreading and spraying) while Section III deals with three cleaning processes (winnowing in the wind and in horizontal and vertical wind tunnels). Section IV uses the program to analyse three other problems, viz, rain, fire and mineral sedimentation. It should be emphasized that these are examples of the application of the program and are not intended to be a complete analysis of the particular problem. Readers who are familiar with fluid - particle mechanics may wish to move directly to Chapter 4. Chapters 9 and 13 are reserved for future use.
