A Simulation and Analysis of the Effect of Temperature Fields and Velocity Fields on Operating Room Standards by Using CFD Software

In this study, the values of temperature and velocity inside the operating room are of interest to analyze and evaluate the design process of buildings that satisfy the set standards and conditions by using Autodesk rendering software and numerical simulation software to build and set initial parameters. The simulation results through analysis show the value of the temperature field with uniform distribution, especially in section 2, with the temperature range from 20 °C to 22 °C satisfying the design criteria for the standard of the operation room. At cross-section 3, the temperature value is reached at the air supply vein with a deal within 15°C in accordance with the original design parameter. For the velocity field results, it is reasonable compared with the parameters of previous studies with the working zone velocity of the doctor and the patient in the range of
$0.068\ m/s$
to
$0.15\ m/s$
which is less than the standard
$0.5\ m/s$
for the standard requirements of the operating room, With the airflow inside the operating room moving at a slow speed, this helps verify that the design process has satisfied the initial requirements. In addition, the slow-moving air flow will help reduce the risk of spreading the virus to the surrounding environment on medical equipment and instruments, especially by creating a comfortable environment that meets the standards of room surgery. From here, the simulation results obtained are positive and very encouraging to minimize the virus dispersion and establish the comfort zone.
