| This book is completed by the basic equations for calculating the air motion in cylinder air flow of a reciprocating internal combustion engine. A calculating model, including a set of differential equations with initial and boundary conditions, is very usefull during the development and design stage of an engine. The aim of this book is to provide the fundamental equations which can be used for flow measurements. The basic principle of the three kinds of Anemometers also be presented in this book. |
