Abstract
The calculation model of uniform air supply square hood was drawn using Gambit, and the boundary conditions of numerical simulation for calculation model were determined combined with the actual situation. The uniform air supply of square hood was simulated for different velocity at hood by Fluent software. The air distributions of the uniform air supply square hood and the air distributions of the hood in the center line were put forward, and the change of the velocity with the distance from the hood face has better change regular, which was found. The hood size and the supply air velocity were non-qualified in order to eliminate the influence of different hood size and supply air velocity. At last, the change regular of supply air velocity with the distance from the hood face was put forward for the uniform air supply square hood.
