Structure of matter BENHARKAT, Zohra The Structure of Matter is a foundational science course exploring the physical universe build. The present document for the Structure of Matter module has been designed to meet the needs of first year License students, particularly those pursuing a first degree in Science and Technology (L1). Its primary focus is on providing comprehensive instruction in fundamental concepts of matter structure, a captivating of general chemistry. The curriculum for Common Core in Science and Technology students delineates this course into six distinct chapters and then focuses on the view of fundamental concepts, principal components of matter, radioactivity, electronic structure of an atom, periodic classification of the elements and chemical bonding.

Heat Transfer FERRAH, Abdelkader Heat transfer is directly related to numerous problems in many engineering and scientific applications. It is perhaps the most important, as well as the most applied process, in refining, gas processing, and chemical and petrochemical plants. This course on heat transfer is intended for second-year students in process engineering, as well as anyone who needs to acquire a foundation in this discipline. It conforms to the official curriculum issued by the Ministry of Higher Education and Scientific Research. Through the various chapters, the reader will be introduced to the modes of heat transfer. They will thus be able to identify the mechanisms and calculate the quantities of thermal energy that migrate from one medium to another.

Documentary research and dissertation design KOUADRI, Amar The master's program in mechanical engineering, as in any other discipline, concludes with the preparation and defense of a final cycle project. This final step before obtaining one's degree is of great importance in a student's education. It represents a particularly intense period in terms of workload as well as stress for those preparing their dissertation. The public defense is also a source of apprehension and anxiety for most students. It is therefore very important to be able to prepare one's dissertation methodically in order to succeed during this important period of student life. This course is addressed to Master's 2 students in mechanical engineering, in the energetics option, who are about to prepare their final cycle project. Indeed, all Master's 2 students are concerned and need to acquire a good methodology to properly prepare their final projects. The content of this course conforms to the official program issued by the Ministry of Higher Education and Scientific Research. Throughout the various chapters, the reader will be introduced to documentary research and will learn the steps, methodology, and techniques for writing and presenting a dissertation. In summary, this course is designed to help students prepare their dissertations from start to defense and to guide them in adopting the appropriate approach. It is worth noting that this course is also of great use to recent graduates entering professional life, as they will often be called upon to prepare projects and present them effectively, communicating in the best possible way in the workplace.

TP TURBOMACHINES KOUADRI, Amar Avant-propos Ce polycopié de travaux pratiques en turbomachines est destiné spécialement aux étudiants de la 3ème année licence Énergétique (S5) ainsi qu'aux étudiants du domaine des Sciences et Techniques de l'enseignement supérieur. Le manuscrit est constitué de séances de travaux pratiques accompagnées de protocoles expérimentaux détaillés et de tableaux de résultats, conformément au programme de turbomachines agréé par le ministère. Le premier TP constitue une introduction expérimentale à l'étude d'une pompe centrifuge seule, à travers la détermination de ses caractéristiques de performance : la charge hydraulique, la puissance absorbée, la puissance hydraulique et le rendement global, en fonction du débit volumétrique. Elle aborde également l'analyse adimensionnelle par le calcul du nombre de Reynolds à différentes vitesses de rotation. Le deuxième TP élargit cette étude au couplage de pompes centrifuges, en examinant successivement le fonctionnement d'une pompe seule, le montage en parallèle et le montage en série. Cette approche progressive permet à l'étudiant de comprendre l'influence de la configuration hydraulique sur les performances globales du système de pompage. L'ensemble de ces travaux pratiques s'appuie sur un banc d'essais instrumenté, équipé d'un variateur de vitesse, d'afficheurs de pression numérique, d'un tube Venturi pour la mesure du débit et d'un système d'acquisition de données optionnel (VDAS), offrant ainsi des conditions expérimentales proches de la réalité industrielle.
