Experimental Methods II (FSI-IEE)

Academic year 2023/2024
Supervisor: prof. Ing. Jan Jedelský, Ph.D.  
Supervising institute: EÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
Students will be made familiar with experimental and optical measuring methods in environmental engineering, heat transfer and mechanics of fluids.
Learning outcomes and competences:
Students acquire theoretical and practical knowledge and learn to work with experimental equipment and with computer systems for records evaluation.
Prerequisites:
Knowledge of physical laws from thermodynamics, heat transfer, mechanics of fluids and optics.
Course contents:
The course deals with special experimental methods in environmental engineering, optical visualization and measurement methods. These methods are used in flow visualization, visualization of temperature fields, heat transfer and in the dynamics of fluids and solids.
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:
Course-unit credit requirements: attendance at exercises, handing in laboratory records. The evaluation consists of results from laboratories. The examination consists of written and oral parts.
Controlled participation in lessons:
The work in laboratories is checked by reports and by checking computer-based evaluation of visualization records.
Type of course unit:
    Lecture  13 × 2 hrs. optionally                  
    Laboratory exercise  13 × 1 hrs. compulsory                  
Course curriculum:
    Lecture
