This diploma thesis deals with verifying the thermal conductivity and other thermophysical properties of different types of wood (spruce, oak, ash and maple). A special device ISOMET 2104, which is based on dynamic method of measurement, was used. Three different samples for each type of wood were used (for example, different age of trees). Values of the thermal conductivity, the thermal diffusivity and the specific heat capacity, depending on the gradually decreasing moisture of wood, were obtained. The key point of this study was finding that the values of thermophysical properties of wood materials vary significantly depending on the age, growing conditions, properties of the soil and other factors. Some of the data correspond with previously published studies but other data are in contrast to them.

The diploma thesis is focused on the design of the timbered wall composition considering the low-energy and passive standard. Main goal of the thesis is to calculate heat transfer coefficient U for four different types of the timbered walls and consequently evaluate if they comply with the requirements of low-energy and passive standards. The calculations show that the traditional concept of the timbered structures is inefficient for the mentioned energy standards. The minimal thickness of the timbered wall which will satisfy the requirements of the energy standards for low-energy and passive structure were calculated for the proposed four types of wall composition. For the calculations methods according to the applicable standards ČSN were used. To verify accuracy of these method and the performed calculations simplified numerical model was made in finite element software.

This master thesis is a part of the project TAČR TREND, which aim is the development of new ingredient for treatment of dry eye syndrome. Developed ingredient is derivative of hyaluronic acid, which is in this thesis compared with native hyaluronic acids and commercial eye drops. Aim of this thesis is to describe rheological and tribological properties of measured samples in terms of viscosity, mucoadhesivity and coefficient of friction. Coefficient of friction was measured on created tribological model of the eye in pin-on-plate configuration which represents physiologically relevant sliding speeds of blinking. Comparison with native hyaluronic acids and commercial products of eye drops showed, that derivative reaches higher values of viscosity, has mucoahesive properties and has low values of coefficient of friction. Those key parameters show that modification of hyaluronic acid is promising way for drug development for dry eye disease.

The master´s thesis deals with the numerical modeling of flow in the emergency spillways of small dams. It is solved the flow rate capacity of a weir and of spillway called „duckbill-type“. Sharp crested weirs and long crested weirs are modeled using numerical simulations in ANSYS. Hydraulically complex spillway called „duckbill-type“ was modeled in the Flow-3D. The results of the discharge coefficients are compared with data in the hydraulic literature.

The last chapter includes a calculation of the safety factor by using a Finite Element Method.

This thesis deals with the calculation procedures for determining the heat transfer coefficient for steam condensers. The first section provides a basic overview for industrial steam condensers and possible procedure for selecting the appropriate type of tube condenser. The next section describes the types of condensation and equations for determining the heat transfer coefficient for various geometries of tubular condensers. In the final section there is performed practical calculation of condenser in Maple software using the above relations. The results obtained in this calculation are compared with the results obtained by professional computational software Chemcad and HTRI.

The diploma thesis concentrates on a project of backpreassure steam turbine. These topics are analyzed in more detail: design of balance schema, thermodynamic calculation, loss coefficient and its effect on the loss. Technical solutions are designed according to given details of a steam and chosen conditions of use.

This thesis in introductory part aims to analyze the available literature on the heat transfer coefficient in labyrinth seals and rotating discs of steam turbines. The available experiment studies were processed to summarize heat transfer coefficients on the rotating parts of the turbine. Then, this thesis specifies a design calculation to determine the heat transfer coefficient in selected parts of the turbine, exercisable for specific geometric and operating parameters. The outcome of this work is simulation of rotor dilation of operating steam turbine in the program Ansys during cold start of turbine.

The master´s thesis focuses on design of intake manifold with swirl flap for diesel engine. In addition to the design of sub-components of the intake manifold are also investigated the influence of new solutions on engine parameters. The influence of the new solution is compared to the original version and a reference model simulating intake manifold used by competitors. After simulation of thermodynamics and fluid flow are evaluated each variants.
