Course detail

Experimental Methods II

FSI-IEEAcad. year: 2021/2022

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.
