An Estimation of Wave Attenuation Factor in Ultrasonic Assisted Gravity Drainage Process
It has been proved that ultrasonic energy can considerably increase the amount of oil recovery in an immiscible displacement process. Although many studies have been performed on investigating the roles of ultrasonic waves, based on the best of our knowledge, little attention has been paid to evaluate wave attenuation parameter, which is an important parameter in the determination of the energy...
متن کاملCharacterization of Cement-Based Multiphase Materials Using Ultrasonic Wave Attenuation
To my family and friends who make me who I am ACKNOWLEDGEMENTS This work would not have been possible without the support from a number of people who encouraged me during my stay in the United States. Most importantly, I would like to thank Prof. Laurence 'Larry' Jacobs for being an outstanding advisor, teacher, and friend, supporting me in an unprecedented way during my stay at Georgia Tech. F...
متن کاملUltrasonic Attenuation in Solid Helium
A great deal of information about the motion of dislocations in solid helium has been obtained from ultrasonic and interna1 friction measurements. A brief review is given and representative data for 3 ~ e are presented, showing dislocation resonance and damping as well as pinning effects.

متن کاملAttenuation of ultrasonic waves in rolled metals.
Scattering of ultrasonic waves in polycrystals with texture is studied in this article. The attenuations of the three wave modes are determined as a function of dimensionless frequency and propagation direction, respectively, for given orientation distribution coefficients (ODCs). The calculation is done in the case of a statistically orthorhombic sample made up of cubic crystallites. The wave ...
