| Abstract: | Taking the SCR reactor of 600 MW unit in one thermal power plant as the object,seven defferent schemes of baffle plate design and arrangement have been numerically simulated by using the advanced computational fluid dynamics software ANSYS-CFX 10.0.Through speed vector plot and introduction of concept concerning relative standard deviation,the results of simulation have been qualitatively and quantitatively analysed and compared,and the optimal scheme of baffle plate design and arrangement being determined. |
