hello, everyone
i am trying to simulate a poolfire in the open space these days. but i can't get the right result. the boundary conditions are labeled on the following picture. chosen models: K-ε model; non-premixed combustuion model;prePDF material: ch4-air [IMG]file:///D:/geo.jpg[/IMG] and the temperture field is as the following picture [IMG]file:///D:/result.jpg[/IMG] it seems that the outside air can't disperse into the computation area smoothly. Please tell me the reason of the bad result, thank you ! |
