LEARNING OUTCOMES

This course provides an overview of the different fields of Applied Physics. The aim of the course is to allow students to gradually advance to solve transdisciplinary problems through an educational path that is tailored to actual design issues. Throughout the course various issues will be covered, such as problems related to heat and mass transfer and to hygrometry, as well as analyzing light sources and artificial lighting.

AIMS AND LEARNING OUTCOMES

By the end of this course, students will be expected to:
- know the main physical qualities of applied physics and their relevant units of measurement;
- be able to describe and study the transformations of thermodynamic processes;
- know the fundamental laws of kinematic, dynamic, thermodynamics, fluid mechanics, and heat transfer;
- be able to perform simple analyses of thermofluidynamic phenomena;
- solve simple problems relating to energy transformation, kinematics and dynamics of a material point, fluid dynamics, heat transfer by conduction, convection and/or radiation.

PREREQUISITES

Students have to know properly and deeply the main topics and means of Mathematics.

TEACHING METHODS

The teaching consists of both theoretical lectures and applied lessons. The first ones introduce the main topics, the latter deepen the knowledge and give examples of applications.

Attendance to the lessons is not mandatory but is highly recommended to maximize the teaching impact and to ease the students’ learning.
