An Experimental Study on the Reconstruction of Three-Dimensional Temperature Fields in Flames

2011
This 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.

Three-Dimensional Temperature Field of a Rectangular Array of Practical Air Jets

Industrial & Engineering Chemistry Research, 1994
The 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 ...

Modeling transient three-dimensional temperature fields in mountain permafrost

2008
Permafrost 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.

THE FIELDS OF TEMPERATURE, PRESSURE, AND THREE-DIMENSIONAL MOTION IN SELECTED WEATHER SITUATIONS

Journal of Meteorology, 1947
Abstract The fields of temperature, pressure, and three-dimensional motion are shown on horizontal charts and vertical cross sections for a period of anticyclogenesis above a polar anticyclone and for periods of cyclogenesis in Colorado and on the east coast of the United States.

THE ACCURACY OF BEAM-AVERAGED INTERFEROMETRIC TEMPERATURE MEASUREMENTS IN A THREE-DIMENSIONAL FIELD

Experimental Heat Transfer, 2001
A classical or holographic interferometer can be used to measure the average fluid temperature integrated in the direction of the test/object beam. However, such beam-averaged measurements are not exact for a three-dimensional temperature field, when a standard two-dimensional analysis technique is applied.

Measurement of three-dimensional temperature fields using multidirectional holographic interferometry

The study of three-dimensional flow phenomena is applicable to a large number of thermal engineering systems. Optical tomography using multidirectional interferometric data holds great promise to quantitatively investigate three-dimensional flow and heat transfer phenomena.
