Inhalable Particles Transportation of the Kitchen in Different Ventilation Methods

摘要

In order to evaluate the particle exposure level of people indoor, and to improve indoor air quality, research for the particle distribution in residential kitchen is important. In this paper, a residential kitchen is investigated numerically, and the spread and distribution of particles are simulated detailed using the mixture two-phase model. We focused on the particles transportation in different ventilation methods. The four different conditions are designed for simulating the two-phase flow pattern, and the results of particle concentration of different ventilation methods and different particles diameters are obtained. The simulating results are beneficial for increasing the particle removal efficiency and the design of reasonable ventilation methods.
