| Zusammenfassung: | <jats:title>Abstract</jats:title> <jats:p>The objective of this work lies in the three-dimensional study of the thermo mechanical behavior of a blade of a centrifugal compressor. Numerical modeling is performed on the computational code "ABAQUS" based on the finite element method. The aim is to study the impact of the change of types of blades, which are defined as a function of wheel output angle <jats:italic>β</jats:italic> <jats:sub>2</jats:sub>, on the stress fields and displacements coupled with the variation of the temperature.</jats:p> <jats:p>This coupling defines in a realistic way the thermo mechanical behavior of the blade where one can note the important concentrations of stresses and displacements in the different zones of its complex form as well as the effects at the edges. It will then be possible to prevent damage and cracks in the blades of the centrifugal compressor leading to its failure which can be caused by the thermal or mechanical fatigue of the material with which the wheel is manufactured.</jats:p> |
