Do you have trouble spending your library budget? Do you end up buying so many hooks you cannot store them? If so, this is the book for you. Spend US$ 328.25, and you only have to devote 30 mm of shelf space to this book. Your librarian will also be pleased: the book is so boring that no one will want to steal it or even take it off the shelf more than once. The book is actually a collection of selected papers from a conference held in Kyoto, Japan in April 1995 under the title of the Second International Conference on Multiphase Plow. Seventy papers are published here from the three hundred and twenty presented at the conference. We are assured that all the papers in this volume were reviewed by at least two referees up to the normal archival standards. The papers presented here cover the whole range of multiphase studies from theoretical turbulence modelling to experimental studies of flooding, critical heat flux, nucleate boiling, condensation, and fluidized beds. It is this diversity which makes this volume less than totally useful. The lack of a subject index does not help; the author index is not much compensation. How much better it would have been if these seventy papers had been published in the relevant established journals? In this volume the papers will get lost and not be referenced by other works as many of them should be.

It is difficult to give any clear idea of the quality of the papers in this review. Not surprisingly they vary considerably from the banal to the very interesting. Inevitably I concentrated on the titles which were interesting to me: DeJesus et al. used a photochromic dye technique to measure, non-intrusively, the liquid velocities near a Taylor bubble. The results look very convincing. Manolis et al. found that to correlate slug frequency, it was better to use an old correlation than to use much more recent ones. Katayama et al. found that the position of a hydraulic jump in a horizontal stratified flow was generally affected by external variables in a way which seems consistent with intuition. Yamaguchi et al. show that in gas-liquid flow in a horizontal pipe rotating about its axis the gas tended to agglomerate on the axis: again an intuitive result. . Lund and Perkins describe an attractive optical technique used to determine gas bubble position, size, shape arrd orientation, but only for one bubble at a time. What is particularly welcome is that many of the papers feature novel instrumentation techniques, but, as the average paper is only about 12 pages long, there is not enough space to describe the new techniques adequately. The papers are reproduced from the author’s copy. Mercifully the style is a fairly uniform and pleasing double column layout. Other things are not so consistent: somereference lists contain titles; others do not; some papers include a nomenclature list; many do not. P.B.
