Moving interfacial boundary estimation in stratified flow of two immiscible liquids using electrical resistance tomography

Abstract: This work is concerned with the interfacial boundary estimation in stratified flows of two immiscible liquids using electrical resistance tomography. The interfacial boundary is parametrized with front points and the unknown positions of the front points are estimated based on the relationship between the injected currents and the induced boundary potentials. It is assumed that the interfacial boundary moves during the time taken to collect a full set of independent measurement data. In order to find the unkno… Show more

“…The Fourier coefficients are estimated using boundary element method approach with Levenberg-Marquardt method. Several approaches are applied to elliptic PDE problems where the boundary is recovered based on the data from the exterior boundary using certain boundary conditions [8][9][10][11][12][13][14][15]. The methods presented in the above papers are based on specific elliptic PDE problems and the boundary is recovered by using certain boundary conditions and the data from the exterior domain boundary.…”
