CODE 108756 2024/2025 9 cfu anno 2 INGEGNERIA DELL'ENERGIA 11438 (L-9) - SAVONA ING-IND/10 Italian SAVONA 1° Semester AULAWEB

OVERVIEW

"Fisica Tecnica" is the name by which we refer in Italy to the disciplines of Thermal Engineering: Applied Thermodynamics, Energetics and Energy Conversion including from Renewable sources, and Heat Transfer. In English, these disciplines are known as Applied Thermodynamics and Heat Transfer.

AIMS AND CONTENT

LEARNING OUTCOMES

The course provides the fundamental notions of technical thermodynamics, heat transmission, energy to solve engineering problems related to heat exchange and work in industrial and civil contexts

EXAMS

EXAM DESCRIPTION

The exam is in two parts, written examination (solution of an Applied thermodynamics or heat transfer problem) followed by an oral examination on course topics.

Final exam mark is the average of written and oral exam marks

ASSESSMENT METHODS

Discussions during lectures with students and Team discussions outside frontal lectures
