Experimental analysis of air stream from a car blower using smoke method and design of the blower quality assessment
 Krška, Lukáš ; Šedivý, Petr (referee) ; Jedelský, Jan (advisor)
The aim of this work was the analysis of air current from the right outlet, using the smoke method and the subsequent determination of a method for application. A further task was to establish a method for determining the upper and lower vertical routing, yaw angle (ß) and angle of inclination (?) of the air current. The experiment aims to approximate conditions as close to those experienced in the actual vehicle. After assembling a track with a soot blower (outlet) in the laboratory and defining the coordinates of the vehicle, the air current was subjected to visualization within the range of five positions of the vanes. Visualization was achieved by the use of technology for the smoke method. We used a light plane with a customized system of coordinates, a smoke generator for visualizing the air current being emitted and a camera for recording images. During our research we established the upper and lower cut off at the specific closures of the horizontal vanes of the soot blower. We determined a common analogy between the experimental track used in the experiment and the circumstances in the actual vehicle. We acquired the yaw angles (ß) and the angles of inclination (?) in the light plane and, after conversion, in the system of coordinates of the vehicle for all five settings of the vanes. The assessment of the given soot blower was undertaken according to the values achieved.

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.
