Natural convection heat transfer between vertical parallel plates with symmetric and asymmetric heating

The effect of the flowability of dust on the collection performance of filter cloth was studied by using three kinds of dusts of different flowabilities. In the case of dislodging the filter cloth, the amount of dust remaining on the dislodged filter cloth was considerably affected by the flowability of the dust. For dust of low flowability, pressure drop across the filter cloth and collection efficiency were higher than for dust of high flowability when the same amount of dust remained on the filter cloth.
