Visualization of air jet from ventilation outlet of a passenger car dashboard
Bečica, Radek ; Bělka, Miloslav (referee) ; Lízal, František (advisor)
Goal of this master´s thesis is to experimentally analyse air jet from ventilation outlet of a passenger car dashboard using smoke visualization and to describe this air jet. Air flow was set at 30 m3/h according to requirements from Škoda Auto s.r.o. from previous experiments on a similar ventilation outlet. First type of measuring rig which was developed for previous experiments was disassembled and replaced with a new modern measuring rig which is supposed to be used for next visualizations and experiments. Visualization was performed using smoke method and laser light plane. Air jet was photographed for five defined ventilation outlet adjustments and that for a jet to free space and for a jet flowing along a wall. The wall represented a front left door of a car. Results were processed by computer and presented as pictures and tables. Resulting angles were transformed to the main coordinate system of a car. Ventilation outlet functionality with respect to the air distribution in a car was evaluated afterwards.

Evaluation of noise of ventilation outlet for a passenger car cabine
Libřický, Stanislav ; Vaňková, Marie (referee) ; Jedelský, Jan (advisor)
The thesis deals with issues of noise ventilation outlets in a passenger car. There is a description of the noise reduction in the acoustic background, optimizing experimental measurement methodology and familiarization with measuring equipment. The next step includes measuring of individual outlet options, results post-processing and comparison of tested alternatives. Based on these results the best variants are chosen and measures for decreasing noise in the ventilation outlets are proposed.

Testing of ventilation outlets for a passenger car cabin
Dohnal, Martin ; Zaremba, Matouš (referee) ; Jedelský, Jan (advisor)
This thesis deals with experimental testing of car cabin ventilation outlets. In first part the main characteristics of air flowing are made and applied on stream from outlet. Next part deals with function and impact of car cabin ventilation system. Another part is dedicated to overview of commonly used metod of outlet testing. Research of usage of different type of outlets in mid-class cars was made. The main part of this thesis is done in final part where the testing is described by the smoke visualisation with use of laser knife and evaluation of results is performed.

Air conditioning design in multifunctional sports hall
Navrátil, Radek ; Uher, Pavel (referee) ; Blasinski, Petr (advisor)
The diploma thesis deals with the design of air-conditioning equipment in the building of a multifunctional hall in Brno and also includes an experimental analysis of air flow. It consists of 3 parts. In the first part a theory of air distribution is elaborated. The second part deals with the analysis of air flow for different types of air diffusers and for one diffuser further looks for a simplified model. The last part of this work is focused on the design of air conditioning equipment in the assigned building, the multifunctional sports hall.

Evaluation of functionality of ventilation outlet in passenger car cabin
Caletka, Petr ; Kamenský, Petr (referee) ; Jedelský, Jan (advisor)
This work engages in flow boundaries detection that flows from a car ventilation outlet. Smoke visualization was chosen for the flow visibility. There were applied three detection methods on the pictures with different types of quality. It was evaluated a suitability of these detection methods for the pictures with different types of quality. This suitability was evaluated based on the detected shapes of the flow and obviously based on the detected direction angles.
