Teaching Methods
THE COURSE IS BASED ON LECTURES AND EXERCISES IN THE CLASSROOM. IN THE EXERCISES, IT IS TAUGHT HOW TO USE PROFESSIONAL SOFTWARE TO SOLVE SOME COMBUSTION PROBLEMS.
Verification of learning
THE EVALUATION OF THE ACHIEVEMENT OF THE EXPECTED OUTCOMES WILL BE CARRIED OUT WITH AN ORAL INTERVIEW.
THE ASSESSMENT OF THE LEARNING OUTCOMES, CARRIED OUT IN THE FINAL EXAMINATION, WILL TAKE INTO ACCOUNT THE FOLLOWING EQUIVALENT CRITERIA: A) KNOWLEDGE AND ABILITY TO SOLVE MAJOR ISSUES THAT REQUIRE THE APPLICATION OF EXPRESSED CONCEPTS; B) KNOWLEDGE OF THE BASIC ASSUMPTIONS AND LOGIC OF THE DISCIPLINE; C) ABILITY TO EXTEND THE APPLICATION OF BASIC CONCEPTS TO SOLVE ISSUES IN NEW APPLICATIONS, D) PROPERTY OF LANGUAGE WITH PARTICULAR REFERENCE TO THE SPECIFIC TERMINOLOGY OF THE DISCIPLINE.
