Application of an anemometric hot-wire probe to the measurement of a velocity field downstream of an automotive ventilation outlet
 Šíp, Jan ; Tuhovčák, Ján (referee) ; Lízal, František (advisor)
This diploma thesis deals with the research of the flow in front of the benchmark automotive vent. Using thermoanemometry, the velocity field in the area in front of the vent was measured in detail and the intensity of the turbulence was calculated. Computational fluid dynamics of the air flow from the vent was also performed using the STAR-CCM + program. In addition, the influence of the surrounding surfaces simulating the real environment of the automobile on the air flow from the vent was investigated. The diploma thesis contains the calculation of measurement uncertainty. The purpose of this thesis is to obtain complex data on the velocity field and to use them for validation of Computational fluid dynamics.

Ventilation in a light duty vehicle – research on defrost of windshield and its efficiency.
 Hapala, Radim ; Krejčí, Vladimír (referee) ; Lízal, František (advisor)
The diploma thesis deals with research of the jet issuing from the defrost duct of Skoda Octavia car. Components of velocity and turbulence intensity were measured using hot wire anemometry. Obtained data were presented in graphs and contour maps. Results were confronted with previous research.

Experimental analysis of automobile ventilating outlet air flow using hot wire anemometry and draft of outlet quality rating
 Ležovič, Tomáš ; Šedivý, Petr (referee) ; Lízal, František (advisor)
The master’s thesis deals with air flow in the interior of automobile Škoda Octavia. The attention is focused only at a side ventilating outlet. Author’s effort was to propose the appropriate criteria for evaluation and assessment of ventilating outlet quality and elaborate the methodology of measurement for these criteria. Then follows the application of the methodology and measurement of velocity field of air flow from the outlet by the method of hot wire anemometry. The thesis also contains comparison of the results with the results attained by the smoke visualization.
