ANALYSIS METHOD FOR NONSTEADY THERMAL CONDITION OF SOLID BODY Russian patent published in 2014 - IPC G01N25/18 

FIELD: heating.

SUBSTANCE: principle of the proposed method implies that nonsteady thermal condition of a solid body is provided by exposing the front face surface of the solid body to the contactless non-destructive thermal action of an infrared radiation source. Temperature condition of the solid body is registered in certain points of the coordinate space as per the pattern: in the solid body depth at y=0 and z=0 at the section x∈[0, δ], where δ stands for the solid body thickness, in the points in the amount of N+1 with coordinates x=0, δ/N, 2δ/N, …, (N-1)δ/N, δ; on the solid body surfaces at x=0 and x=δ in the coordinates complying with the requirements |y|≤(0.9÷0.95)a and z≤(0.8÷0.9)b, where a and b stand for geometrical characteristics of solid body surfaces. Basing on the experimental data the nonsteady temperature field of the solid body is drawn up according to the space-time coordinates.

EFFECT: improved accuracy of the obtained data.
