A method for the determination of the amount of solid particles reaching the wall of a coal gasifier was developed to predict the adhesion phenomena of particles to the furnace wall. Experimental measurements of the rate of arrival (adhesion) at the wall of particles flowing in a straight tube were compared with the numerical results. The experimental arrival rate could be represented numerically by analyzing the simplified two-fluid model. Comparison of the calculated result with the result of Direct Numerical Simulation result confirmed that the thermophoretic force increased the amount of solid particles reaching the wall. This is an abstract of an article originally published in Kagaku Kogaku Ronbunshu (vol. 29, no. 6, pp. 795-801, November 2003).
