The effect of particle clustering on char combustion has investigated in terms of three dimensional direct numerical simulation. To compute the flow field with and without particle clustering, Stokes number is set to almost zero and 1.92. Numerical results have shown that particle clustering affects gaseous concentration distribution, and consequently, carbon conversion behavior of coal particle. The higher gaseous temperature, the more remarkable such effect becomes to be. Carbon conversion is suppressed up to 10% by the effect of particle clustering. These results indicate that new char combustion model, which is taken into account of the particle clustering effect, should be developed.
