  • The measurement and simulation of indoor air flow

    A numerical simulation applying the computational fluid dynamics (CFD) solver Fluent 6.1.22 was performed displaying inspiratory intranasal air temperature and airflow patterns. Results: Due to resection of the turbinates the airflow pattern is disturbed resulting in a …

  • A detailed simulation of air flow after sneezing

    2021-6-30 · In a coughing event that lasts for 0.4 seconds and has a maximum exhaled air speed of 4.8 m/s, the flow first generates a turbulent stream of air that is hotter and more humid than that of the environment. Once the expiration is over, the stream turns into a puff of air that rises because of flotation and its lack of weight while it dissipates.

    2019-12-12 · Simulation results also indicate that an OFA nozzle angle set below 30° moves the mixing point of the OFA flow and the up-flowing gas downward, further aiding combustion in the upper furnace. However, when the angle increases above 30°, OFA is unable to reach the furnace center, weakening combustion in the furnace, because no reaction with ...
