EFFECTS OF PARTICLE SHAPE AND CONFIGURATION ON THE THERMAL CONDUCTIVITY OF A POROUS MEDIUM
Sinopsis
Based on a lumped parameter method, algebraic
expressions for effective thermal conductivities of porous
media consisting of in-line elliptic cylinders (20) and
ellipsoids (3D) with connecting bars are obtained. It is
shown that the shape of the particles is important in the
effective thermal conductivity of a porous medium if the
solid/fluid thermal conductivity ratio is in the range of 10
< ks/kf < 103.
