A Way to Use Waste Heat to Generate Thermoelectric Power
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
In recent years there has been rising interest in thermoelectric generation as a potential source of electric power using waste heat. This paper describes thermoelectric power generation from waste heat from biomass boilers, ...
A Flexible Adjustment and Control System for Hydraulic Machines
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Due to the advantages of hydraulic systems with variable displacement, it was necessary to design a control system that can adjust the pressure, flow, power or a combination of these features, that can be easily integrated ...
Explosion Cladding of Lead on Steel
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This work deals with explosion cladding of lead on steel. The welded materials and the Semtex S type explosive are characterised. The preparation of the welded materials and the proposed welding assembly are described. The ...
Contributions to the Study of Dynamic Absorbers, a Case Study
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Dynamic absorbers are used to reduce torsional vibrations. This paper studies the effect of a dynamic absorber attached to a mechanical system formed of three reduced masses which are acted on by one, two or three order x ...
Simulation of Free Airfoil Vibrations in Incompressible Viscous Flow — Comparison of FEM and FVM
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper deals with a numerical solution of the interaction of two-dimensional (2-D) incompressible viscous flow and a vibrating profile NACA 0012 with large amplitudes. The laminar flow is described by the Navier-Stokes ...
Synthesis of Mechanisms by Methods of Nonlinear Dynamics
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper deals with a new method for parametric kinematic synthesis of mechanisms. The traditional synthesis procedure based on collocation, correction and optimization suffers from the local minima of objective functions, ...
Massive Parallelization of Multibody System Simulation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper deals with the decrease in CPU time necessary for simulating multibody systems by massive parallelization. The direct dynamics of multibody systems has to be solved by a system of linear algebraic equations. ...
Hygro-Thermo-Mechanical Analysis of a Reactor Vessel
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Determining the durability of a reactor vessel requires a hygro-thermo-mechanical analysis of the vessel throughout its service life. Damage, prestress losses, distribution of heat and moisture and some other quantities ...
A Numerical Study of Wind Flow Over a Coal Storage Shelter
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper presents some of the main numerical results obtained while simulating the wind flow over a shelter covering a coal storage. The aim of this numerical study was to evaluate the change in flow patterns caused by ...
Transonic Flow of Wet Steam — Numerical Simulation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
The paper presents a numerical simulation of the transonic flow of steam with a non-equilibrium phase change. The flow of steam is approximated by a mixture model complemented by transport equations for moments. Proper ...
