Ventilation of a clean room in electronic industry
Tichý, David ; Štětina, Josef (referee) ; Charvát, Pavel (advisor)
The work describes an air conditioning and circulation system of a clean room environment in of a semiconductor production site. It is based on given requirements for air cleanness, temperature preasure and relative moisture. The first half of the work describes the way the system should work, classification of construction and operation of the site. The second half describes the calculations of the given parameters on which the system is designed. The calculations deal with - Air exchange and maintaining the required parameters - Designing the muti stage air filtration system - Designing the air flow speed, intake and outlet parameters of the air conditiong distribution system - Desingning the air conditioning units and their possitioning in the utility room

The Delivery of the Mixture Containing Abrasive Particles.
Hrabina, Martin ; Sluše, Jan (referee) ; Štigler, Jaroslav (advisor)
The aim of this bachelor thesis is focused on description of the transport equipment parts used in some industries for delivering of the mixture containing abrasive particles. The thesis is divided into some captures. Each of them deals with the transport issues. The first part of the thesis is focused on the flow of liquid in transport equipment. Second part describes particular parts of pumps and compares various kinds of them, highlighting their advantages. One of the significant topics of the thesis is the characterisation of pipeline using for the above mentioned transport.

Advanced laser diagnostic systems to measure flow field
Loutocký, Petr ; Lízal, František (referee) ; Jedelský, Jan (advisor)
The aim of this work is to give readers a comprehensive view of the present laser methods for measuring the velocity of fluid flow. The methods are classified and compared according to various criteria. Individual techniques are briefly outlined their principles of measurement, options and range of applications. Furthermore, this work discusses the advantages and disadvantages, appropriate areas of application and the basic parameters. At the end we can find a sample analysis of data measured by one method.

Komplexní charakterizace prachových frakcí ve volném ovzduší (AirToxPM)
Masarykova univerzita, Brno ; Klánová, Jana
Stručný popis prací v rámci projektu, jehož cílem je snaha co nejlépe charakterizovat fyzikální, chemické a toxikologické vlastnosti prachových částic. Projekt zahrnuje výzkum a identifikaci jejich primárního zdroje, charakterizuje jejich sorpční potenciál. Zabývá se modelováním chování, studiem jejich dalšího osudu, délkou setrvání v atmosféře a toxikologickými efekty. Byly vyhodnoceny analytické výsledky, které umožnily stanovení míry rizik plynoucích z expozice prachovým částicím pocházejících z různých zdrojů a různých velikostí. Je připravena metodika hodnocení vlivu polétavého prachu pro regionální a lokální studie. Jsou uvedeny citace publikačních výstupů i vlastní texty článků.
