Dear All,
I am trying to perform simulation of a radiation problem in an enclosure filled with air and dust particles. The enclosure has a cylindrical shape(dia=0.025 mm, length=500 mm) and external radiation comes in from the circular cross-section and has a conical profile. Please refer to the image attached for a better understanding of the problem. I am using the discrete ordinates radiation to model the physics. I have set the following parameters in the Fluent Software: Theta, Phi Divisions: 8 Theta, Phi Pixels: 4 Beam Width: 1e-5(both theta and phi) Beam Direction: (1 0 0) Diffuse fraction: 0 However, the beam that I am getting not what I had expected, The red contours in the figures when matched gives a perfect conical profile, however, the neighboring green and blue contours are unnecessary and I want to get rid of it. I tried to play with the above parameters but no improvement was observed. Looking forward to your support. Regards, Subham |
