Estimation of Thickness of the Sediments in a Circular Pipe by Finite Element Method
This paper presents an approach that estimates the thickness of the porous sediments on the bottom of a circular pipe by comparing the measured propagation modes’ frequencies to that calculated by finite element method (FEM). It is validated by comparing the calculated results to the theoretical results for the circular pipes with rigid boundary condition and to the experimental results with sediments laid on the bottom of the pipe. The comparison results show that the disagreements between measured thickness and the calculated thickness are less 3 percent. This method can be used to monitoring or measuring the depth of the sediments on the bottom of a pipe in confined situations.
