I disagree with the previous review; simply looking at the table of contents does not give any clue about whether the book is easily accessible, particularly well-written, ... But sure, from the table of contents, one deduces that the scope of the book is rather broad; a good point;
Using this book, I was able to calculate the free-fall velocity of a quartz particle in still air; fine, but the authors do not provide any information on the accuracy of the methods they present though the great deal of measurements of free-fall velocities (particularly of water droplets) must allow to quantify the uncertainty attached to their methods; this highly-relevant information is missing.
In fact, stated bluntly, the book seems more a catalog of references than what I was expected: A book that provides thorough and easily understandable explanations on physical phenomena associated with multiphase flows. And how to numerical solve them. For instance:
8.2.3 Direct numerical simulation models: it deserves 3 paragraphs, 10 papers will be referenced;
8.2.5 Discrete vortex methods: it deserves 2 paragraphs, citing 8 papers;
and you will find in 8.2.5:
"These studies show the tendency for the particles to concentrate on the peripheries of the vortices when the Stokes number is of the order unity"
what is the underlying physics ? no answer; a bit later:
"[They] show that the presence of the particles slows the development of the shear layer". No further explanation or implications thereof;
Some sections must be definitely overhauled:
the section on erosion for instance. On this topic alone, you could write plenty of books. So the authors rightly must content themselves to summarize the research in this field; even in this respect, they failed: They refer to some highly specialized papers, instead of citing 3 or 4 first-rate papers that provide a good overview of the studies in this domain, like "Erosion Caused by Impact of Solid Particles" by Tilly and "Some Reflections on the Past and Future of Erosion" by Finnie, even though biased.
In the section on the drag coefficient, the plot of the drag coefficient as function of the relative Reynolds number shows discrepancies between experimentalists, and thereupon a "standard curve"; the authors do not precise how this standard curve was derived; What is desperately missing are also examples that highlight the order of magnitudes of the terms in the BBO equation.
The section on non-spherical particles is fairly thin; the Wadell's method, which dates back to 1933, is presented, but there are no further references, though this topic is of tremendous importance; still in this domain, the book fails to present integral values to describe non-sphericity of particles.
For the technical content, I would ascribe the book 3 stars; because of the price (!), I withdraw one star; The book is not that bad; This is simply the kind of book you borrow, not buy.
