This master thesis deals with determination of boundaries of the flow from a benchmark automotive vent (right-front situated – in front of a front passenger) using the smoke visualization. In this thesis is tested a pack of eight different constructional variants which differ among them by the type of deflection grille. The angles of the flow borders are compared to specific directional requirements (defined by ŠKODA AUTO a.s.) and there is evaluated a directability of each of the constructional variant on the bases of these results. The results of experiments show that better directability in vertical plane achieve deflection grilles with horizontal vanes situated closer to orifice of the vent or deflection grilles with higher number of horizontal vanes and lower number of vertical vanes (independently of their location). Directability of the deflection grilles in horizontal plane is analogically better with vertical vanes situated closer to orifice of the vent or with deflection grilles with higher number of vertical vanes and lower number of horizontal vanes (independently of their location).

The goal of this work is to experimentally assess the influence of limiting walls of Škoda Octavia 3 automobile cabin to the air jet flowing from the right-front situated automotive vent which is part of a car dashboard. The experiment is performed by the smoke visualization method. There is a single construction option measured for an experiment. The setup of the vanes direction and the air flow rate are modified for this option. The experiment is divided into two phases. In the first phase, the visualization of the free air flow is conducted. In the second phase, exit plates are constructed and consequently, the visualization of the wall-jet flow is conducted. The results of both are compared to each other. The results imply that the influence of the surrounding surfaces must be taken into account with the increasing flow rate for the vanes set in the direction of upper-right, middle-right, and middle-middle. There is a direct interaction between the flow and exit plates (the flow impact, the Coanda effect). The free flow does not contain the information about the mutual interaction between the flow and the exit plates, as it is in the case of the wall-jet flow. In the case of the wall-jet flow, the opening of the flow takes place due to the effect of the impact and the subsequential suction caused by the Coanda effect. The exit plates substituting the car dashboard and the front window contribute to the prevention of the air intake from surrounding space and consequently to earlier flow opening from the vent. The present work also contains the measurement methodology and the image evaluation, the comparison with previous free flow measurements (70% match) and the comparison to the measurement of hot-wire anemometry method.

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.

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.

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.

The thesis describes the evolution and variances in the motive of crime and punishment throughout prosaic and dramatic works of František Langer. After an introductory reflection on crime and punishment the thesis deals with an analysis of Doskojevskij's novel "Crime and Punishment" which had a large impact on Langer's conception of these terms. It also outlines an image of crime and punishment in Czech literature at the turn of the 19th and 20th century, which might have influenced Langer. The first part also tries to clarify how these motives were evolved in author's incipient work. It follows up prose collections "Gold Venus" and "Dreamers and Murderers". The second part is focused on the refined and often very complicated form of crime and punishment in Langer's dramas "Saint Wenceslas", "Periphery", "Camel through Eye of a Needle", "Reversal of Ferdyš Pištora", "Angels among us" and "Seventy-two" and tries to grasp and characterize it.
