Forward Modelling and Inversion of the Ultrasonic Wave Propagation Through a Homogeneous and Porous Rock
MetadataShow full item record
The aim of my work is to estimate viscoelastic parameters of rock samples from waveforms of ultrasonic waves propagating through these samples. To this end, I develop an automated Python modules in Finite Element Modelling software Abaqus, and tailored it specifically for a controlled transmission experiment using ultrasonic source and receiver. The approach is verified using test Aluminium samples, and then applied to real rocks to estimate ultrasonic attenuation using Prony formulation of viscoelasticity.

Effect of Ultrasonic, Microwave and Combined Microwave–Ultrasonic Pretreatment of Municipal Sludge on Anaerobic Digester PerformanceYeneneh, Anteneh; Chong, Siew; Sen, Tushar; Ang, Ha Ming; Kayaalp, A. (2013)Anaerobic digestion is one of the most effective means for the stabilisation of sludge. However, it has a very slow rate-limiting hydrolysis phase which is attributed to the low biodegradability of cell walls and the ...
