N2 - A constant temperature difference is imposed between the two bases of a horizontal solid slab containing a fluid-filled fracture that crosses the slab at an angle to the horizontal. The distortion of the vertical thermal gradient due to the presence of the fracture induces a natural convection flow in the fracture, which is analyzed along with the temperature distributions in the solid and in the fluid, in the limit of small Rayleigh numbers. The numerical and analytical results compare favorably with the temperatures and velocities measured experimentally.
