It has been my great pleasure to read this book, a series of exercises and a course review, written by Nord-Eddine Sad Chemloul.

The book addresses dimensional analysis and similarity, tools for solving specific problems in fluid mechanics, and is intended for students of mechanical engineering, civil engineering, maritime engineering, and other similar fields.

The book’s author has taught this subject for over 25 years and has acquired a great deal of experience, allowing him to perfect his course over the years.

The book is firmly structured and well written, making it an easy read. It is divided into three chapters. The first chapter concerns the calculation of dimensions, the verification of the homogeneity of relationships, and the conversion of units. The second chapter introduces the homogeneity method (or Rayleigh method) and the Vaschy-Buckingham method (also known as the n method), which are used in dimensional analysis. The third chapter provides a study of the comparison of fluid flows using similarity.

The book’s numerous exercises, the product of the numerous works and tests prepared by author, are accompanied by detailed and thoroughly commented corrections. This book is also intended for educators.

I highly recommend it for students, since it provides them with the essential elements of dimensional analysis and similarity as applied to fluid mechanics.
