摘要: 为解决吸油烟机在高管道阻力的情况下,基于FLUENT稳态算法计算无法收敛且模拟值与实际值误差较大的问题,提出了在仿真模型出口域建立减压筒模型,通过调节减压筒出口处面积来施加管道阻力,重点研究了吸油烟机在高管道阻力下气动性能、噪声和吸烟效果的模拟数据与实测数据的差异。研究结果表明,仿真模型的优化对吸油烟机在高管道阻力下的性能仿真数据具有很大的修正性,气动性能模拟误差值能保持在7%以内,噪声模拟误差值在10%左右,吸烟效果模拟与实际测试有较高的匹配度。研究结果对吸油烟机仿真平台的搭建及性能优化提升具有指导意义。

Abstract: In order to solve the problem that the error between simulated and actual value calculated of range hood in the case of high pipeline pressure based on the FLUENT steady-state algorithm, a decompression cylinder model is proposed to be provided at the outlet of simulation model, and pipeline pressure is added by adjusting the area of outlet. Aerodynamic performance, noise and lampblack exhausting of range hood under high pipeline pressure is studied with focus on the error between simulated and actual value. The research results show that the optimization of simulation model has great corrections to simulation data of range hood under high pipeline pressure. The error of simulated aerodynamic performance is 7%, the error of simulated noise is about 10%, and the simulated lampblack exhausting is corresponding to actual situation. The research results have guiding significance for simulated platform construction and performance optimization of range hood.
