Meshing and Turbulence Modeling Problems with Internal Baffles …

12/12/2020 · I need to help for my case. I want to model an industrial-scale CFB boiler with internal baffles. I tried to solve it at different times and different meshing and modeling approaches. This is my geometry. My boiler has a one rectangular baffle + some u beams. When I tried to run with just a rectangular baffle, my problem can be solved. But I try to mesh for u beams, my simulation can't be

Boiler stop valves. A steam boiler must be fitted with a stop valve (also known as a crown valve) which isolates the steam boiler and its pressure from the process or plant. It is generally an angle pattern globe valve of the screw-down variety. Figure 3.7.3 shows a typical stop valve of this type.
