To review the model quality, a validation is being performed. For this purpose the results of 1D-simulations are compared to appropriate 3D-simulations. This shows a good qualitative and quantitative agreement. In addition, the validation is performed by means of measurements on a pulsation test bed. This reveals major deviations between measurements and 1D-simulation. Discussing potential reasons for these deviations leads to the presentation of a new concept for the test bed.enVÁLVULA DE RETENCIÓNVALIDACIÓNBANCO DE PRUEBA DE PULSACIÓNTesis de Maestría
