Lines of Gas-pipeline are going due over different soil environment. In some regions, for example sliding slopes brings stresses into the pipes. We need to know stress le [...]

Programming robot PLC controller through voice recognition system has been presented. The purpose of this project is a development of a robot control voice protocol allow [...]

The paper describes the results of experiments with a rotating golf ball moving quasi-steadily in calm water. The motion of the ball was recorded on a digital video camer [...]

The ring stiffness is determined by experiments for the thermoplastic sewerage pipe. The numerical simulation is convenient to use in the case of the new corrugated pipe [...]

The gallery wall on which the Bas-reliefs are etched of the Bayon temple in Angkor is made of sandstones. The deterioration caused by penetration of rainwater or groundwa [...]

The point of this paper is the comparison between the different kind of shapes turbine blades in relation to efficiency of the stage. The first part of the paper deals wi [...]

The paper describes effects of end wall shaping in guide blades on steam turbine stage efficiency. CFD and measurement of straight blade cascades in a wind tunnel were pe [...]

The principle of a steam turbine balanced control system is presented here. The dynamic stress measurement method in parts of valves on its models in the aerodynamic wind [...]

Specific feature of the nuclear power plants is in comparison with coal fired plants the break postulation of each high energy piping. Fluid system is considered as high- [...]

Experimentally investigated pressure pulsation downstream of the control valve cone is presented here. The valve with the mufflers and the flat bottom is compared with th [...]

Paper focuses on possibilities of transient processes modelling at pressure pipe system of a non-nuclear part of a certain power plant and summarizes the results of relat [...]

Outcomes of a numerical simulation of flow through an unbalanced control valve during the turbine's operational modes. A 2D as well as a 3D calculation study is considere [...]

Moving load is such a load, which vary both in time and space. As the result the stress state of piping increase and frequency spectrum decrease. If the flow velocity is [...]

The aim of this contribution is comparing the results of the solution of steam piping response to the guillotine rupture at the variation of some parameters of the select [...]

Abstrakt: In all power plants (classical and nuclear) are used safety relief valves. After opening of this ones the mass of fluid (gas or steam) begin to move with very h [...]
