Compressional wave phase velocity measurements during hydrate growth in partially and fully water saturated sandstone
Sæther, Mathias Myrtveit; Almenningen, Stian; Ersland, Geir; Lunde, Per (Journal article; Peer reviewed, 2022)The compressional wave phase velocity (cP) has been measured as a function of hydrate saturation (SH) during hydrate growth in Bentheim sandstone. The Fourier spectrum signal processing technique was used to specifically ... -
Customization of the angular spectrum method for calculating the acoustic piston field transmitted through a solid plate using MATLAB
Sæther, Mathias Myrtveit (Journal article; Peer reviewed, 2023)The angular spectrum (AS) model is customized to calculate the spatial acoustic pressure field generated by a piston source and transmitted through a steel plate immersed in water, for normal beam incidence. A MATLAB program ... -
Interaction of three-dimensional acoustic beam with fluid-loaded solid plate: Axial near- to far-field transmission at normal beam incidence
Sæther, Mathias Myrtveit; Midtbø, Simen Hammervold; Lunde, Per (Journal article; Peer reviewed, 2022)Axial radiation from leaky Lamb waves propagating in a 6.05 mm water-immersed steel plate being excited by a sound beam normally incident to the plate, is investigated as a function of axial distance, z, and frequency, f, ...
