Embodiment Construction
[0035] Select the particle source, establish an open-air open particle source physical model, and design an appropriate calculation domain to determine the entrance and side wall conditions necessary for the calculation, specifically as figure 1 shown.
[0036] Use non-uniform tetrahedral grids to divide the calculation domain space around the particle source, and follow the principle of "near wall encryption", that is, the area close to the physical model of the particle source adopts fine grids, and the distance uses sparse grids, such as figure 2 shown. Afterwards, the sensitivity verification of the grid division method is carried out until the influence of the grid division method on the calculation results is controlled at ≤ 5%.
[0037] The steady-state k-ε two-equation turbulence mathematical model is selected, the governing equation is written as a general conservation equation, the equation is discretized into a difference equation by the finite volume method, and ...
