The subject matter is divided into several fields. In each field the principles of the given experimental method are explained and its usability for experimental research of energetic machines is shown. Follows list of covered subjects: " Basic modeling theory o Dimensional analysis " Pressure measurement o Manometers o Total and static pressures probes o Mean flow direction measurement " Temperature measurement o Thermocouples o Other sensors (Pt, thermistors) o Optical methods (infrared, interferometer) o Liquid crystals " Velocity measurement o Pressures " Incompressible flows " Compressible flows " Supersonic flows o Hot sensors o Optical methods " Point measurements (LDA) " Fields measurements (PIV) " Skin friction measurement o Evaluation from velocity profiles o Direct force measurement (floating element) o Pressures measurements (fence, Preston probe) o Hot films o Optical methods (wall visualizations) " Pipe flow measurements o Turbines o Pressures evaluation o Ultrasound methods o Forces on bodies o Vortex flow-meters o Rotameter o Other principles (Coriolis force, heat mark) " Visualization o Tracer particles o Laser sheet o Smoke wires o Wall methods (paints, liquid crystals, oil film) " Fluid density measurement o Shadow method o Schlieren method o Interferometry " Fluid viscosity measurement " Force and moment measurement - aerodynamic balance " Data acquisition and evaluation " Wind tunnels o Discontinuous - continuous work o Open - closed (close-circuit) o Subsonic - transonic - supersonic - hypersonic
