The science of rheology remains a mystery to most people, even to some scientists. Some respectable dictionaries have been quite cavalier in their attitude to the science, the small Collins Gem dictionary, for example, being quite happy to inform us that a Rhea is an three-toed South American ostrich, whilst at the same time offering no definition of rheology. This maybe due to the fact that the science is interdisciplinary and does not fit well into any one of the historical disciplines. This book contains an in-depth study of the history of rheology, beginning with the statements of Heraclitus, Confucius and the prophetess Deborah. It also emphasises the distinctive contributions of Newton, Hooke, Boltzmann, Maxwell, Kelvin and others, and culminates in the flourishing activity in the second half of this century. Features of this book: • Is the only book on the subject • Prevents the rediscovery of results already made • Will educate newcomers to the field to the rich heritage in even a relatively recent science like rheology. The book will be invaluable for science and scientific history libraries and will also be of interest to rheologists, and scientists working in the polymer processing, food, lubrication, detergent and similar industries.
More than possibly any other scientific discipline, rheology is easily visualized and the relevant literature contains many excellent photographs of unusual and often bizarre phenomena. The present book brings together these photographs for the first time. They are supported by a full explanatory text. Rheological Phenomena in Focus will be an indispensable support manual to all those who teach rheology or have to convince colleagues of the practical relevance of the subject within an industrial setting. For those who teach fluid mechanics, the book clearly illustrates the difference between inelastic fluids and viscoelastic fluids in a number of important flow fields. For example, the influence of the configuration of molecules in an entry flow, the influence of rounding corners, the reluctance of elastic liquids to turn corners, and the sensitivity of elastic fluids to asymmetries in the flow are clearly illustrated. In addition many flow instabilities, where fluid elasticity is clearly the dominant variable, are shown.
Numerical Simulation of Non-Newtonian Flow focuses on the numerical simulation of non-Newtonian flow using finite difference and finite element techniques. Topics range from the basic equations governing non-Newtonian fluid mechanics to flow classification and finite element calculation of flow (generalized Newtonian flow and viscoelastic flow). An overview of finite difference and finite element methods is also presented. Comprised of 11 chapters, this volume begins with an introduction to non-Newtonian mechanics, paying particular attention to the rheometrical properties of non-Newtonian fluids as well as non-Newtonian flow in complex geometries. The role of non-Newtonian fluid mechanics is also considered. The discussion then turns to the basic equations governing non-Newtonian fluid mechanics, including Navier Stokes equations and rheological equations of state. The next chapter describes a flow classification in which the various flow problems are grouped under five main headings: flows dominated by shear viscosity, slow flows (slightly elastic liquids), small deformation flows, nearly-viscometric flows, and long-range memory effects in complex flows. The remainder of the book is devoted to numerical analysis of non-Newtonian fluids using finite difference and finite element techniques. This monograph will be of interest to students and practitioners of physics and mathematics.

This is the Companion to the New Believer's Guide of 50 Steps With Jesus. Jesus is inviting you to walk with Him. He is asking you to spend your life in an adventure with Him. It is an adventure that will never end. It is personal. It is you and Jesus. He made you for this special relationship and deeply desires this time with you. This guidebook is a tool created to assist you in helping others on this journey with Jesus. The Shepherd's Guide provides lesson overviews, prompts, step-by-step instructions, key verses for students to memorize, and questions for their growth and reflection. Each day you will help your student take new steps with the Lord, exploring His truths, growing closer to Him, and becoming more secure in the foundations of the faith. Week 1: Who Am I Now? Week 2: Following Jesus Week 3: More Ways to Talk With God Week 4: Understanding the Bible Week 5: Being a Part of the Church Week 6: Worshiping God Week 7: Walking With Jesus
Does the idea of marketing yourself make you uneasy? Do you hate the idea of sales, but have something valuable to share? If you have struggled with marketing-placing a value on yourself, your products, or your services, then Selling Without Sleaze is for you. Wendy K. Walters uses biblical principles and common sense to show you how to market yourself without selling your soul.
In "A Grammar of Dazaga," Josiah Walters provides a detailed description of Dazaga, a Saharan language. Based on recent data, the author describes the phonology, morphology, and syntax of Dazaga, relating his findings to related languages and recent typological studies.
