一个研究流体相对于颗粒系统的运动的人很快就会对存在于理论和实践方面的书籍之间的二分法留下深刻的印象。经典流体动力学主要涉及理想流体，不幸的是，理想流体不对它们运动经过的粒子施加力。对诸如流化、沉淀和多孔介质中的流动等问题的实际研究方法有很多有用但不相关的经验信息。本书代表了一种尝试，以弥合这一差距，至少提供了一个合理的方法，流体粒子动力学的开端，第一原则的基础上。从教学的角度来看，似乎值得表明，纳维尔-斯托克斯方程，它构成的基础上，所有系统的文本，可以用于有用的实际应用超出了基本问题的层流在管道和斯托克斯定律的运动的一个单一的粒子。虽然悬浮液在实际应用中常常被看作是一个连续体，但它实际上是由浸没在基本上连续的流体中的离散颗粒组成的。考虑这种观点所引起的实际的详细的边值问题，可能有助于引起人们对适用于流体和固体颗粒混合物的整体输运性质的理想化的限制的注意。
One studying the motion of fluids relative to particulate systems is soon impressed by the dichotomy which exists between books covering theoretical and practical aspects. Classical hydrodynamics is largely concerned with perfect fluids which unfortunately exert no forces on the particles past which they move. Practical approaches to subjects like fluidization, sedimentation, and flow through porous media abound in much useful but uncorrelated empirical information. The present book represents an attempt to bridge this gap by providing at least the beginnings of a rational approach to fluid particle dynamics, based on first principles. From the pedagogic viewpoint it seems worthwhile to show that the Navier-Stokes equations, which form the basis of all systematic texts, can be employed for useful practical applications beyond the elementary problems of laminar flow in pipes and Stokes law for the motion of a single particle. Although a suspension may often be viewed as a continuum for practical purposes, it really consists of a discrete collection of particles immersed in an essentially continuous fluid. Consideration of the actual detailed boundary value problems posed by this viewpoint may serve to call attention to the limitation of idealizations which apply to the overall transport properties of a mixture of fluid and solid particles.
