Ant mound as an optimal shape in constructal design: solar irradiation and circadian brood/fungi-warming sorties //Journal of Theoretical Biology. (355) 2014. p. 21-32
    Annotation Sizes, shapes, ambient and in-dome temperature, incoming solar radiation and illumination are measured on a Formica rufa anthill in a mixed forest of the Volga-Kama National Reserve in Russia. These data are used in a conceptual model of insolation of a right conical surface by direct-beam, descending atmospheric and ascending ground-reflected radiation. Unlike a standard calculation of the energy flux intercepted by a solar panel, the anthill is a 3-D structure and double-integration of the cosine of the angle between the solar beams and normal to the surface is carried out for a ?cozy trapezium?, where the insects expose themselves and the brood to ?morning? sunbathing pulses (Jones and Oldroyd, 2007). Several constructal design problems are formulated with the criteria involving either a pure solar energy gained by the dome or this energy, as a mathematical criterion, penalized by additive terms of mechanical energy (potential and friction) lost by the ants in their diurnal forays
    Keywords social insects, adaptive ant-mound, insolation, direct-diffuse-reflected radiation on non-flat surfaces, optimal slope.
