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

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

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 …

One of the primary challenges with additively manufactured metal components is the
potential for the material heterogeneity, such as the variations in density, porosity, and …

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 …

Extreme environmental conditions are common in energy conversion applications, in which
the most hardened insertion sensors often do not perform reliably for long. On the other …

Extreme conditions are common in energy conversion, material processing, nuclear,
airspace, and military applications. In such environments, the most hardened insertion …

Temperature distribution in solids can be inverted from the speed of sound (SOS)
measurements, as has been shown feasible by timing the propagation of the excitation …

Many industrial processes are inaccessible or inhospitable to characterization by traditional
temperature measurement methods, such as thermocouples, especially over prolonged …
