ABSTRACT: This paper presents the results of laboratory tests conducted to investigate ultrasonically enhanced water flow rates using vibration energy of polyvinylidene fluoride PVDF film. Vibration is used widely in engineering, medicine and many aspects of daily life. One of the application is dewatering of saturated porous media was enhance using ultrasound. Vibrations were generated using PVDF Film with various frequencies 0 20 kHz and amplitude as the innovative technique. The test conditions involved various frequencies, amplitude and thickness of soils. The test results show that increasing wave energy and frequency can increase water removable from soil. This is one idea of soil remediation methods using flow by vibration.

RÉSUMÉ: Cet article présente la modélisation ainsi que les résultats des tests effectués pour étudier ultrasons qui renforcent le débit d'eau utilisant l'énergie des vibrations de fluorure de polyvinylidène PVDF film. La vibration est largement utilisée dans l'ingénierie, la médecine et de nombreux aspects de la vie quotidienne. Une des applications est l'assèchement de PVDF film avec différentes fréquences de 0 à 20 kHz et l'amplitude comme ceux de la technique innovante. Les conditions d'essai se composent de diverses fréquences, l'amplitude et l'épaisseur des sols. Les résultats des essais montrent que l'augmentation de ence peut augmenter d'eau amovible de terre. C'est une idée des méthodes de décontamination des sols utilisant des flux par les vibrations.
