3D CFD model for the analysis of the flow field through a horizontal axis wind turbine (HAWT)
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)With the world’s growing demand for energy, renewable energy production has become important in providing alternative sources of energy and in reducing the greenhouse effect. This study investigates the aerodynamics and ... -
Compression behaviour and failure mechanisms of a safety culvert made of hollow high-performance concrete blocks
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)The safety culvert composed of hollow high-performance concrete blocks is designed to reduce the risk of injury in the event of a collision. This work presents a new design with an opening for water flow, tests it, identifies ... -
Construction of angular-dependent potentials from trigonometric Pöschl-Teller systems within the Dunkl formalism
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)We generate solvable cases of the two angular equations resulting from variable separation in the three-dimensional Dunkl-Schrödinger equation expressed in spherical coordinates. It is shown that the Dunkl formalism ... -
Effect of cross-sections data on calculated static neutronic parameters of PWR MOX/UO2 core transient benchmark case using NODAL3 code
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)This paper describes the effect of cross-section data generated by several codes on calculated neutronic parameters. The Pressurized Water Reactor Mixed Oxide and Uranium Oxide (PWR MOX/UO2) Core Transient Benchmark case ... -
Shock wave configuration in a transonic flow through a mid-section of a last stage turbine blade cascade equipped with a part-span connector
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)This paper deals with the study of a flow field and namely the configuration of shock waves in a blade cascade equipped with a part-span connector called tie-boss. The cascade consists of prismatic blades formed from the ... -
The effects of potassium permanganate on the geotechnical properties of soils
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)In Nigeria, potassium permanganate (KMnO4) is used as a chemical oxidant in the removal of hydrocarbons from polluted soils and groundwater, but there is no information on the effects of KMnO4 on the geotechnical properties ...
