Abstract EN
The inlet grid and exhaust grid are widely used in engineering machinery products.
The process that airflow goes through grids is a complex turbulent flow and directly related to the heat dispersion and aerodynamic noise.
The theoretical analysis result shows that the jet noise generated by airflow has a connection with the grid structure form, fluid flowing situation, and heat conduction.
In addition, the influences of different grid structure forms (included the round hole, long hole, and square hole) and porosity on the heat dissipation and aerodynamic noise were analyzed and presented based on the verified computational fluid dynamics (CFD) model.
Results show that the heat dispersion and aerodynamic noise of the round hole are most effective under the same porosity; as the porosity increases, the disturbance degree decreases and the noise reduction effect gets better.
Finally, the research result provides the scientific basis for improving grid structure and achieving energy saving and noise reduction.
