Description

This technical report summarizes the research performed and progress achieved during the period of October 1, 1995 to December 31, 1995. The measurements of gas flow in the advanced FBC test chamber (10 in. I.D.) was continued to better understand and utilize the fluid dynamics of gas and particle flows in the advanced FBC. Measurements showed that the gas flow field in the test chamber is characterized by strongly swirling flow in tangential direction and developing flow in axial and radial directions. In addition, multiple secondary air injection caused significant effects on gas flow in the freeboard of the test ... continued below

Description

This technical report summarizes the research performed and progress achieved during the period of October 1, 1995 to December 31, 1995. The measurements of gas flow in the advanced FBC test chamber (10 in. I.D.) was continued to better understand and utilize the fluid dynamics of gas and particle flows in the advanced FBC. Measurements showed that the gas flow field in the test chamber is characterized by strongly swirling flow in tangential direction and developing flow in axial and radial directions. In addition, multiple secondary air injection caused significant effects on gas flow in the freeboard of the test chamber. Numerical simulation of typical gas flow patterns in the freeboard was conducted using a computational fluid dynamics (CFD) code, FLUENT. The axial velocities resulting from theoretical prediction were smaller than the tested results. However, the predicted radial velocities at the exit zone of the test chamber were greater than that of the tested results. The calculated results showed the non-isotropic structure with vigorous fluctuating in axial and radial directions. Generally speaking, the predictions of the theoretical calculation agreed with the experimental results. The measurements of gas and particle flows will be continued under different test conditions. In addition, the numerical simulation on gas and particle flows will be continued, which will be compared with the experimental results.
