Acoustic tomography is a technique widely used in nonintrusive temperature measurement.
The time of flight (TOF) of acoustic waves can be used to estimate the temperatures of a …

A novel approach that uses noninvasive ultrasound to measure the temperature distribution
in solid materials is described and validated in high-temperature laboratory experiments …

In this study, a high-speed, fast responsive, non-intrusive ultrasonic thermometry system was
proposed as a potential candidate for overcoming the disadvantages of thermocouples. The …

In the past, few researchers have presented objective criteria that can be applied for the
stability assessment of a gasification process for woody biomass. When exploring new …

Thermal heterogeneities within energy conversion and storage, material processing, nuclear
processes, aerospace, and military applications are often inaccessible to characterization by …

Acoustic tomography (AT), as a noninvasive temperature measurement method, can
achieve temperature field measurement in harsh environments. In order to achieve the …

A method for noninvasive ultrasound measurements of temperature distribution in solids is
described and experimentally demonstrated in the estimation of an axial distribution of the …

In extreme environments, even hardened insertion sensors fail quickly. For such
environments, we have developed an ultrasonic (US) method for measuring the spatial …

The most hardened insertion sensors do not perform reliably in extreme environmental
conditions. We address this problem by developing an ultrasonic thermometry system for the …

The short service life of refractory lining in a slagging gasifier in the integrated gasification
combined cycle results in low availability and high operating cost. For longer life of the …
