1 To extend the level of understanding on the effect of fines on the different types of particle size distribution on the minimum bubbling point with both rigid porous and rigid non-porous powder.
2 To prove the predictability of the existing empirical correlation on the minimum bubbling point with both rigid porous and rigid non-porous powder.
3 To prove the predictability of the theoretical correlation on the minimum bubbling point with both rigid porous and rigid non-porous powder.
