Course detail
Experimental Methods II
FSI-IEE Acad. year: 2020/2021 Summer semester
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.

Learning outcomes of the course unit
Students acquire theoretical knowledge and learn to work with optical experimental equipment and with computer systems for records evaluation.
Prerequisites
Knowledge of physical laws from thermodynamics, heat transfer, mechanics of fluids and optics.
Planned learning activities and teaching methods
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.
Aims
Students will be made familiar with experimental and optical measuring methods in environmental engineering, heat transfer and mechanics of fluids.
Specification of controlled education, way of implementation and compensation for absences
The work in laboratories is checked by reports and by checking computer-based evaluation of records.
