Ash & pulverized coal deposition in combustors & gasifiers. Quarterly technical progress report, April 1, 1995--June 30, 1995
In the period of April 1, 1995 to June 30, 1995, a computational model for simulating particle motions turbulent flow condition is developed. The model was applied to the analysis of particle transport and deposition processes in a circular duct and in a plane recirculating region. The mean gas velocity and turbulence intensity fields were first estimated using the available experimental data, as well as those obtained from an earlier developed CFD code. A model for evaluating particle deposition rate in the presence of gravitational and electrical forces in turbulent flows was also formulated. Results concerning the deposition velocity of particles under various conditions were obtained. It was shown that the model predictions are in good agreement with the available experimental and digital simulation data. Experimental study of glass fiber transport and deposition rate is also initiated.
