Simultaneous three-dimensional measurement of temperature and velocity fields in swirling combustion
Real-time Photonic Measurements, Data Management, and Processing VI, 2021Simultaneous measurement and visualisation of multi-parameters are crucial in understanding and characterising complex combustion. A measurement technique coupled with deflection tomography and particle image velocimetry was proposed to obtain three-dimensional temperature and velocity fields of swirling combustion. A combustion system was developed

Three-Dimensional Temperature Field of a Rectangular Array of Practical Air Jets
Industrial & Engineering Chemistry Research, 1994The temperature field was measured below a representative section of a rectangular array of 165 air nozzles. The array was arranged in a rectangular pattern with three side-by-side columns. On the basis of energy conservation considerations, a single equation was developed that fits the data and can be used to predict the temperature at any position ...

An Experimental Study on the Reconstruction of Three-Dimensional Temperature Fields in Flames
2011This chapter firstly analyses the fundamental principles of the measuring system. Then, for the solution of the 3-D temperature distribution, which is an ill-posed problem, a modified Tikhonov regularization method is established. Digital simulation and a test on our experimental bench is made to validate the new measuring technique.

Measurement of a three-dimensional temperature field applying ESPI and CT techniques
Optics Communications, 1988Abstract Electronic speckle pattern interferometry (ESPI) and computer tomography (CT) techniques are combined to measure a three-dimensional temperature or density field. The method is especially applicable to measurements on asymmetrical fields. Theory and experimental results are presented.

Modeling transient three-dimensional temperature fields in mountain permafrost
2008Permafrost is a common and important thermal phenomenon in the subsurface of high mountains. Its degradation due to climate change may lead to adverse effects, such as decreasing stability of infrastructure or an increase in rock falls from permafrost slopes.

A three-dimensional method for the simulation of temperature fields induced by solar radiation
Advances in Structural Engineering, 2018The determination of temperature fields is usually required for the calculation of structural deformation and stress induced by temperature variation. To guarantee the serviceability and safety of structures by improving calculation accuracy, this study presents a three-dimensional structural temperature field simulation framework that accounts for ...

A three-dimensional temperature field calculation for a transformer-type heating element
Russian Electrical Engineering, 2012A mathematical model for calculating the temperature field of a transformer-type heating element with a spatial pole core using the finite element method is described. A computer simulation program of the three-dimensional temperature field is developed, and calculation results for a transformer of 25-kW capacity are given.
