CFD analýza kavitačních jevů v hydraulických strojích
Sedlář, M. ; Zima, Patrik
The paper deals with the CFD analysis of cavitation phenomena in the hydraulic machinery. Both the ANSYS CFX 11.0 package and an in-house software developed in the SIGMA Research and Development Institute and the Institute of Thermomechanics, AS CR v.v.i. are used to study three types of cavitation problems: calculation of the NPSH3 curves, modelling of the cavitation instabilities and prediction of the cavitation erosion.
Compression test of a timber core - ANSYS model and moire interferometry experiment
Micka, Michal ; Minster, Jiří ; Václavík, P.
The paper presents results of modelling a non-standard compression test of timber, executed on small diameter cores in a special testing device.The test is semidestructive - friendly to historic timber. Numerical solution for elastic orthotropic material is correlated with results of moire-intererometry experimental data. The approach enables to define strengths and Young´s moduli of the assessed core.
Force calculations in permanent magnetic bearing
Bachorec, T. ; Šafr, M. ; Kozánek, Jan
Calculation of forces in permanent magnetic radial bearing by means of finite element method is presented and its results are compared with analytical estimates. From these results, the (slightly non-linear) relationship force versus radial displaceme is derived and the working position of rotor in the stator and predicted bearing stiffness are determined.
