Dynamics of the Taylor bubble interface in the vertical counter-current flow was analyzed
with video recordings at 100–800 frames per second. Taylor bubbles in air-water mixture …

Plasma thruster—currently used on many spacecraft—is intensively developing to meet the
new demands of space propulsion. The spatial distribution of the thruster plume is essential …

This study proposes an iterative penalty term-based regularization (IPTR) for electrical
impedance tomography (EIT) imaging. A penalty term in regularization is formed based on …

Electrical impedance tomography (EIT) is a non-invasive, radiation-free imaging technique
with a lot of promise in clinical monitoring. However, since EIT image reconstruction is a non …

A dynamic imaging method using electrical/ultrasonic dual-modality tomography is
proposed to reconstruct the time-varying distribution based on the Bayesian inversion …

This paper introduces a sensitivity matrix decomposition regularization (SMDR) method for
electric impedance tomography (EIT). Using k-means clustering, the EIT-reconstructed …

This work demonstrates the use of an ultrasonic methodology to monitor bubble density in a
water column. A flow regime with droplet size distribution between 0.2 and 2 mm was …

Viewing the complexity of multiphase flows, in which multi-dimensional and time-changing
fluid structures, known as flow patterns, must be captured, electrical impedance tomography …

Owing to the ill-conditioned nature of electrical resistivity tomography and the measurement
error of the hardware equipment, the reconstructed resistivity distribution image often …

Electrical Resistance Tomography (ERT) has the potentialities of non-intrusive techniques
and high temporal resolution which are essential characteristics for multiphase flow …
