“…This phenomenon is important enough to merit its own name: epidemic backdrafts. A backdraft occurs when low oxygen levels suppress an active fire, but fail to fully extinguish some remaining embers, leaving the embers to generate flammable gasses; when oxygen is reintroduced to the environment, the fire quickly reignites (17).…”

COVID-19 has significantly changed our daily lives. Stay-at-home orders and forced closings of all non-essential businesses had a significant impact on our economy. While it is important to ensure that the healthcare system is not overwhelmed, there are many questions that remain about the efficacy of extreme social distancing, and whether there are alternatives to mandatory lockdowns. This paper analyzes the utility of various levels of social distancing, and suggests an alternative approach using voluntary distancing informed by an infectious load index or "infection weather report."

In order to understand the fire safety of the various types of buildings, we need more flexible and efficient performance-estimating methods to verify fire protection safety in various types of buildings. Assuming can utilize computer fire simulation software CFAST / FDS + Evac to analyze Taiwan's domestic fire cases, in order to understand in the different fires heat flow transfer, and toxic smoke diffuse, and human evacuation to escape, and other important fire parameter characteristics, in the building the fire protection safety evaluating to produce the efficiency. This study is used cases of fires in four-story old-style residential and commercial mixed-use buildings to explain building fire performance-based numerical evaluation methods, and to provide quantitative data and reference information in Taiwan performance-based codes creating and the fire protection to project design is helpful in the buildings.

“…It should be noted that in most cases, the accuracy of zone models is less than that of field models, such as FDS. In addition, the accuracy of the zone models is mostly dependent on the experimental data . Developing specialized fire simulation codes is another way of investigating a fire in an enclosure.…”

The buoyancy-induced turbulent flows in complex geometries with internal heat source have important application in enclosure fire dynamics, for example, smoke movement in the situation of fire in tunnels. The majority of computational works studying the fireinduced hot air movement in such cases use a Cartesian coordinate system. Hence, to simulate curved geometries, the Cartesian grid should be refined so that it comparatively matches the geometry. In the present work, a three-dimensional numerical method using nonorthogonal curvilinear coordinate system was developed. Numerical simulations were performed to study the flow structures and the heat transfer characteristics of fire-induced buoyant flow and the effects of using curvilinear coordinates on the result's accuracy and the computational cost. Numerical results were compared with the available experimental data and the results obtained by fire dynamics simulator (FDS) software. The results of the present method showed better agreement with the experimental results when compared with the FDS results.
