| 摘 要： | A new local exhaust ventilation hood is presented. First, the test system in laboratory roomis established. Secondly a mathematical model is developed in terms of the stokes stream function, andthe governing equation is solved using finite-difference techniques. The injection flow of the exhausthood is treated as a boundary condition of the main flow. Experiments results well agree with thesolution of theoretical prediction. The model can, therefore, be used to design this kind of Aaberg hood.

| Abstract: | A new local exhaust ventilation hood is presented. First, the test system in laboratory room is established. Secondly a mathematical model is developed in terms of the stokes stream function, and the governing equation is solved using finite-difference techniques. The injection flow of the exhaust hood is treated as a boundary condition of the main flow. Experiments results well agree with the solution of theoretical prediction. The model can, therefore, be used to design this kind of Aaberg hood. Thirdly the important parameters affecting the performance of Aaberg exhaust hood are taken into account. In the mean time the connection of these parameters is deduced by multivariate linear regression based on the experimental results. The work is useful whether in designing this kind of local ventilation Aaberg exhaust hood or in predicting the hood's work performance. |
