where: T(x, y, z, t) is temperature field
at t moment; [rho], c and [lambda] are density, specific heat and thermal conductivity coefficient of the material respectively, which are correlation with the temperature and other factors; The T [[beta].sup.ij] [[gamma].sub.ij] term is the amount of heat caused by the deformation work; [[beta].sup.ij] is material property coefficient; [[gamma].sub.ij] = 1/2 ([u.sub.i,j] + [u.sub.j,i]), [u.sub.i] is the change rate of displacement, this term represents the influence of the stress field (displacement field) on the temperature field
, called coupling term; [Q.sub.laser] is the laser heat source , which may be expressed as:
The finite element method is used to analyze the wellbore, casing, and formation as a whole and to establish the wellbore and formation temperature field
calculation model at home.
Applying the boundary conditions in function of length of the chip in contact with the tool, respectively with cutting edge we change temperature field
inside the tool.
And the temperature field
in the graphite moderator was calculated by the three-dimensional heat conduction equation on a structured mesh.
It is well known that the thermal model and the relevant parameters of concrete are the basic conditions for studying the space-time character of the temperature field
and also are the prerequisite for accurate calculation of the temperature stress.
The multifield coupling of the AESA antenna is primarily the sequential coupling among the temperature field
, the structural displacement field, and the electromagnetic field.
To this end, a new model coupling mechanical field with a temperature field
of a deployable structure with scissor-like elements (SLEs) based on ANCF is presented.
Current research methods for the temperature field
in asphalt pavement can be divided into two categories.
Therefore the temperature field
can be improved by a proper burial depth of heat pipe.
Analysis of Coil Temperature Field

To let the system reach the present-day anomalous temperature field
, the simulation covers a period of 1 million years.
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
