Temperature Field

Temperature Field

 

the set of temperature values at all points in a given space at a given instant. Mathematically, an unsteady-state three-dimensional temperature field may be described by an equation that expresses the dependence of the temperatures on the three spatial coordinates and time. For steady-state conditions, the temperature field is independent of time. In many cases the dependence of the temperature field on two coordinates—and occasionally on one coordinate—may be considered. A temperature field is represented graphically by means of isothermal surfaces, each of which connects all points of the field having the same temperature. A two-dimensional field is represented by means of a family of isotherms. The distance between isotherms is inversely proportional to the temperature gradient; in this case, the scalar temperature field is associated with the vector field of the temperature gradients.

Therefore the piston (Figure 8, left side) is equipped with 12 measurement sensors which ensure that a temperature gradient from the piston crown to the piston skirt is measurable and useful for the inverse temperature field determination.
For the temperature field, the isothermal conditions have been prescribed for nacelle internal wall (i.
From the physical viewpoint, the process represents a strongly nonlinear and nonstationary multiphysics problem characterized by mutual interaction of magnetic field, temperature field and field of thermoelastic displacements (and corresponding strains and stresses).
After the cabin aiming, airflow field inside the cabin was predicted and then the transient behavior of temperature field during cool down was predicted considering appropriate cabin heat loads including that of solar irradiation and cabin soaking.
The aimed of this study is to investigate the temperature field as well as to examine the effect of time of day on the temperature field.

Therefore the primary interest of an analyst is to predict accurately a temperature field and is related to its temperature stresses at a design stage, since the latter have a critical relevance to trigger fracture mechanisms in FGM structures [4].
In order to obtain exact temperature field some parameters must be precisely known (such as emissivity and temperature of ambient) however, thermographic images provide useful information.
This is due to the restructuring of the temperature field thus reducing the temperature gradient that affects the heat transfer between probes and the ground.
