Abstract:
 Abstract:In order to solve the problem of formaldehyde pollution in northeastern winter,which caused by the poor ventilation and the conventional floor laying method, the mathematical model of indoor formaldehyde distribution was established by C language programming under enclosed condition By using Fluent under this condition, the changing rule and diffusion mechanism of indoor formaldehyde concentration was determined by analyzing its changes over time and distribution respectively The velocity distribution of volatile gas and the concentration distribution of formaldehyde were also studied under the natural ventilation mode The results showed that the concentration of formaldehyde could be kept at relatively low levels under the natural ventilation mode, and it is instructive to improve the indoor air quality
