Biofluid Mechanics is a throrough reference to the entire field. Written with engineers and clinicians in mind, this book covers physiology and the engineering aspects of biofluids. Effectively bridging the gap between engineers' and clinicians' knowledge bases, the text provides information on physiology for engineers and information on the engineering side of biofluid mechanics for clinicians. Clinical applications of fluid mechanics principles to fluid flows throughout the body are included in each chapter.

All engineering concepts and equations are developed within a biological context, together with computational simulation examples as well. Content covered includes; engineering models of human blood, blood rheology in the circulation system and problems in human organs and their side effects on biomechanics of the cardiovascular system. The information contained in this book on biofluid principles is core to bioengineering and medical sciences.

• Comprehensive coverage of the entire biofluid mechanics subject provides you with an all in one reference, eliminating the need to collate information from different sources
• Each chapter covers principles, needs, problems, and solutions in order to help you identify potential problems and employ solutions
• Provides a novel breakdown of fluid flow by organ system, and a quick and focused reference for clinicians

Fluid Mechanics and Biofluids Principles

Abstract

This chapter introduces the fluid mechanics principles. The chapter starts with the history of body fluid and biofluid mechanics since 2500 BC. Then, it reviews the scope of biofluid mechanics and its applications. The chapter clarifies some important aspects, such as dimensions, units and dimensional analysis in engineering equations. By the end of the chapter the basic principles and formulas in fluid mechanics, including density, velocity, pressure, volumetric flow rate and mass flow rate, are explained.

Keywords

1.1 Introduction

1.1.1 History of Body Fluids

Blood has been known to have been used by humans as an applied fluid for thousands of years. Stone Age painters used several different combinations of materials to make their art. Blood was one of these materials. The cave paintings (40,000–8,000 BC) in Asia, Europe, Africa and Australia prove the use of blood as a paint material, and probably before that they realized the importance of blood for the body during hunting and fighting.
