Two-dimensional anomalies of heat conductivity. Models

you are: Two-dimensional anomalies of heat conductivity

We consider here the refraction of a thermal stream connected with four two-dimensional structures of heat conductivity, which though and in strongly schematised kind, can be considered as analogues of certain often meeting geological situations. With one lens L1 can assimilate model the situation resulting sedimentary process or in a final stage of introduction force; it represents also close analogue of the layer which has been cut off by rupture. Two models with two lenses (L2 and L3) give the same set of possible analogies. The folded model (F) helps to present effects which it is possible to expect in folded areas; for convenience (but not for credibility) folds are below cut off, but it has no value for distribution of a thermal stream in folded area or on its surface.

In all models Sr=1,3-104 J / (g-k), r=2,76 g/sm3, a thermal stream through the bottom border of a grid the temperature gradient at lateral borders 25 is accepted equal 65 мВт/м2, and To/km. The grid in all models consists from 101 • 101=10 201 points; in all cases a grid square.

Three kinds of models Were considered: model with one lens, two models with two lenses and folded model (F). Boundary conditions on grid lateral faces are that, that no part of a thermal stream crosses lateral borders.
