4P580 - Physics and measurement methods



Physics and measurement methods. In this course a number of measurement methods is treated that are relevant for experiments in liquid and gaseous flows. The physical background, practical implementation, and limitations of common measurement methods are analyzed in depth. Basic knowledge on fluid dynamics, as covered by the course Transport Phenomena (3B470), is presumed; further background information (optics, lasers, and molecular physics) is provided during the course. The course is taught in the form of lectures.

An overview of the measurements methods:

  • Flow visualisation;
  • Flow rate: orifices, rotameter, indicator, electromagnetic and ultrasound methods;
  • Velocity: Pitot-tube, hot wire and hot film anemometer, laser Doppler velocimetry, particle-image velocimetry, particle-tracking velocimetry;
  • Temperatures and heat fluxes: thermocouples, liquid-crystal thermography, laser-induced fluorescence.

Learning objectives

To attain insight into the physical principles, areas of applications, strengths and limitations of common measurement methods in fluid-dynamics and heat-transfer problems.
