dc.description.abstract | Two-dimensional numerical simulations are carried out to evaluate the enhancement of
natural convection heat transfer in a dielectric liquid resulting from injection induced
annular electro-convection. The liquid is confined between two concentric horizontal
cylinders and subjected to the simultaneous actions of a direct current electric field and
a thermal gradient. A unipolar injection from the inner cylinder introduces free space
charges into the liquid. Numerical results are presented for the configuration of inner
to outer diameter ratio of 0.5 and silicon oil as the working medium. It is found that the
charge injection may induce a strong radial fluid motion, which consequently augments
the heat transfer rate. Due to the linear stability nature of electro-convection, there
exists a threshold value of the electric driving parameter, above which the electrical
enhancement becomes manifest. In addition, when the electric driving parameter is
sufficiently high, the flow is fully dominated by the Coulomb force, and thus heat
transfer becomes independent of the thermal driving parameter. | es |
