The deposition and transportation characteristics of microparticles suspended water flowing vertically downwards through a heated porous column were experimentally studied. The amount of deposited particles at the interface and inside porous column

and pressure change at difference location at the conditions with and without circumference heating

or the effect of temperature gradient perpendicular to the flow direction were focused in this study

in which the porous columns and inlet concentration of suspended fluid were kept the same. In addition

the seepage stability

the tube wall temperature distribution and the relative permeabilities for each section were analyzed. The results showed that the relative permeability kt/k0 was obviously different at different heating temperature gradients while having the same original porous media and inlet concentration of suspensions. The deposition rates both at the entrance interface and inside porous medium increased with an increase of temperature difference

however

the stability of the deposited structure decreased.
