Module: TECHINICAL PHISICS - Module 1
(objectives)
The objective of the module is to provide the basic knowledge of thermodynamics, necessary for solving different application problems of industrial engineering. In the first part of the module, the first and second thermodynamics law will be stated after a brief introduction on basics concepts and definitions. Direct and reverse thermodynamic cycles will be then illustrated on the main diagrams. In the second part of the module some moist air aspects will be addressed. In particular, the main moist air characteristics will be studied in terms of properties and basic transformations, in order to properly design air conditioning systems. In addition to theoretical classes, practice exercises will be carried out on the addressed theoretical topics. The Course will provide the basic concepts of heat transfer by conduction, convection and radiation necessary for solving different application problems of industrial engineering. Basic principles for acoustic design are also provided for both noise control and optimization of sound quality.
Knowledge and understanding: To understand the basic principles of thermodynamic systems including power generation machines, moist air, reverse cycles. Know the methods of heat transfer by conduction, convection, radiation. To acquire basic knowledge on acoustics. Applying knowledge and understanding: By carrying out case studies, the student will be encouraged to develop an applicative skills on the methodologies and techniques acquired. Making judgments: To be able to apply the knowledge acquired to solve simple application problems in the fields of thermodynamics, heat transmission and acoustics. Communication skills: Knowing how to explain, both in written and oral form, the problem and possible solutions of simple situations concerning thermodynamics, heat transmission, moist air and acoustics. Learning skills: Knowing how to collect information from textbooks and other material for the autonomous solution of problems related to the applications of Applied Physics.
