Heat Engines

Course Description

Study program: Mine Mechanization (VII semester -OAS), Petroleum Engineering (VII semester -OAS)

Name of subject: Heat Engines

Instructors: Dr Marija Živković, Aleksandar Madžarević

Status: Optional

ECTS: 5

Prerequisites: Thermodynamics

Course Objectives: The basics of theory of engines with internal and external combustion are given in the course. The aim of the course is to prepare engineers for proper selection, exploitation and maintenance of engines in various fields of mining and other fields of application.

Learning Outcomes: Upon completion of the course, the student is capable to: analyze theoretical and real cycles of the internal combustion engines, understand the energy transformation in the engine; to calculate and analyze engine performance indicators; to understand and analyze schemes of boilers, as well as to calculate the useful work obtained by transforming heat in the engines with internal and external combustion.
