Natural convection about a vertical plate embedded in a bidisperse porous medium
International Journal of Heat and Mass Transfer, (2008)
Abstract
The classical Cheng-Minkowycz study of convection past a vertical
plate embedded in a porous medium has been extended to the case of
a bidisperse porous medium (BDPM). The boundary layer analysis leads
to expressions for the velocity and temperature fields in terms of
a geometrical parameter, an inter-phase momentum transfer parameter,
a thermal diffusivity ratio, a permeability ratio, a thermal conductivity
ratio, and an inter-phase heat transfer parameter. For the leading
edge region, and for an inner layer, a similarity solution is obtained
numerically. This involves the first four parameters, each of which
is a characteristic of the BDPM.
