In this master’s thesis there are summarized fundamental findings about air flow velocity measurements and afterwards introduced the measuring track for automobile car vents, measured object and track arrangement and all used components. Velocity field measurement method is how wire anemometry, and apart from 4 main cases measurements of free air jet, there are velocity profiles in piping measured as an input for CFD simulation. Air vent evaluation criteria are described and their assessment is done for specified cases. Further, there is a CFD simulation presented with comparison to experimental data. Uncertainty of flow rate measured and flow rate setting is determined. Improvement points and encountered issues are presented. Visualization and evaluation program coded in MATLAB environment enables easy data display of CTA results and will serve further vent quality assessment.
Hot wire anemometry, CTA measurement, air vent quality assessment, free air jet, jet spread angle.
