Experimental Methods (FSI-IEM)

Academic year 2023/2024
Supervisor: doc. Ing. František Lízal, Ph.D.  
Supervising institute: EÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
Students learn to work with experimental and measuring devices for environmental engineering, hydrodynamics and power engineering.
Learning outcomes and competences:
Students will acquire theoretical knowledge and learn to work with experimental equipment and computer measuring systems.
Prerequisites:
Knowledge of physical laws from thermodynamics, heat transfer, mechanics of fluids and electrotechnical engineering.
Course contents:
The course deals with experimental methods in environmental engineering, hydrodynamics and power engineering. The course covers the principles of experimental methods, properties of sensors, computer measurements and processing.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes:
It is necessary to complete all laboratory, computational exercises, submit timely elaborated reports from laboratory measurements and pass tests during the semester. The evaluation consists of tests results, theoretical knowledge and of results from laboratories.
Controlled participation in lessons:
The work in laboratories is checked systematically and three tests in a semester are written.
Type of course unit:
    Lecture  13 × 2 hrs. optionally                  
    Laboratory exercise  13 × 2 hrs. compulsory
