Abstract

In the present study, the sensitivity of particle dispersion within a room to the spatial position of the inlet and outlet air register was investigated using the Taguchi method and analysis of variance. For this purpose, 86400 particles with a size of 1µm were uniformly injected from the inlet register into the room at equal time intervals. Different positions for the inlet register (32 positions) and outlet register (4 positions) on the ceiling and floor of the room were considered. Subsequently, the behavior of the particles, as well as the particle deposition and dispersion within the room over a 60-second time period, were examined using the multi relaxation time lattice Boltzmann method. By employing the Taguchi method and L16 orthogonal arrays, the required number of experiments was reduced by 1/8. All specified experiments which suggested by orthogonal array are simulated, and the number of suspended particles in the room were measured. Following the experiments, the effects of each parameter on the output of the problem were determined based on a factor called the signal-to-noise (S/N) ratio and analysis of variance. According to the obtained results, the longitudinal position of the inlet register had the highest impact on the number of suspended particles in the room, accounting for 84.42% contribution. Additionally, the vertical position of the outlet register had the least impact, contributing only 0.16%.
