Course detail

Experimental Methods II

FSI-IEEAcad. year: 2018/2019

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.

Language of instruction

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.
