TL;DR: In this paper, a continuum mechanics approach to two-phase flow is reviewed and an averaging procedure is applied to the exact equations of motion, and the nature of the resulting equations is studied.
Abstract: : A continuum mechanics approach to two-phase flow is reviewed. An averaging procedure is discussed and applied to the exact equations of motion. Constitutive equations are supplied and discussed for the stresses, pressure differences and the interfacial force. The nature of the resulting equations is studied. (Author)

TL;DR: In this article, the authors present the principles of control volume early for use throughout the book and emphasize the constitutive equation that relates deformation to stress, which can be easily generalized to non-Newtonian fluids mechanics.
Abstract: * Presents the principles of control volume early for use throughout the book * Emphasizes the constitutive equation that relates deformation to stress. * Examines in detail the flow of Newtonian fluids-which can often be easily generalized to non-Newtonian fluids mechanics. * Includes many applications on topics like liquid droplets, gas bubbles, microelectronics processing, injection molding, painting and coatings.

01 Jan 2005TL;DR: This paper presents a meta-modelling framework for convection-Cartesian grids that automates and automates the very labor-intensive and therefore time-heavy and expensive process of convection itself.
Abstract: Introduction to Computational Fluid Dynamics is a textbook for advanced undergraduate and first year graduate students in mechanical, aerospace and chemical engineering. The book emphasizes understanding CFD through physical principles and examples. The author follows a consistent philosophy of control volume formulation of the fundamental laws of fluid motion and energy transfer, and introduces a novel notion of 'smoothing pressure correction' for solution of flow equations on collocated grids within the framework of the well-known SIMPLE algorithm. The subject matter is developed by considering pure conduction/diffusion, convective transport in 2-dimensional boundary layers and in fully elliptic flow situations and phase-change problems in succession. The book includes chapters on discretization of equations for transport of mass, momentum and energy on Cartesian, structured curvilinear and unstructured meshes, solution of discretised equations, numerical grid generation and convergence enhancement. Practising engineers will find this particularly useful for reference and for continuing education.
