Analytical and experimental studies for space boundary and geometry inverse heat conduction problems
Inverse Heat Conduction Problems (IHCPs) have been widely used in engineering fields in recent decades. IHCPs are not the same as direct heat conduction problems which are "well-posed". IHCPs are made more difficult since they are inherently "ill-posed"; that is, a small error perturbation will …

Using the inverse heat conduction problem and thermography for the determination of local heat transfer coefficients and fin effectiveness for longitudinal fins
Heat transfer is a physical process in which energy is exchanged. It occurs in numerous applications, such as production of electricity, building climatisation, food preparation,... Since energy consumption has increased tremendously in the last decades and this trend will continue, the concept of …

Stabilized variational formulation for direct solution of inverse problems in heat conduction and elasticity with discontinuities
… the design of finite element methods for inverse problems with full-field data governed by elliptic forward operators. Such problems arise in applications in inverse heat conduction, in mechanical property characterization, and in medical imaging. For this class of problems, novel finite …

Development of inverse methods for reconstruction of flight environments on ablators
… measurements of flight environments on ablative heatshields is both critical for spacecraft development and extremely challenging due to the harsh heating environment and surface recession. Thermocouples installed several millimeters below the surface are commonly used to measure the heatshield …

INVERSE METHOD FOR DETERMINING TEMPERATURE DISTRIBUTION IN MACHINING
… and the workpiece. The present problem is an inverse heat conduction problem which is much more difficult to solve than the direct one due to its ill-posed nature, that is, small changes in the measured interior temperatures will result in big errors in the estimated boundary temperatures. The …

Model studies of plasma heating in the continuous casting tundish.
… operated. The model was equipped with a steam heating system that simulates that simulates the tundish plasma heating systems operated by some of the more modem continuous casting plants. Similarity between steam heating in the water model and plasma heating in the tundish has been established. …

Hydrodynamics and Transient Heat Transfer Characteristics in Fluidized and Spouted Beds
Hydrodynamics and heat transfer characteristics found in fluidization were studied in a small scale laboratory fluidized bed. Experiments were designed to capture field data on multiple slit jet gas distributor systems for the validation of computational models. Localized data was quantified …

Estimation of Unsteady Nonuniform Heating Rates from Surface Temperature Measurements
… the flow structures relate to the deleterious heat fluxes. In these studies, localized fluid jets created by shock interactions impinge on a test cylinder, where the temperature due to the heat flux is measured. These measurements are used to estimate the heat flux on the surface as a result of …
