Numerical assessment of ceiling-mounted air curtain on the particle distribution in surgical zone

The airflow distribution in an operating room plays a vital role in preventing surgical site infection by diluting and removing particles released by medical staff, lowering particle settlement on a patient. This study aims to computationally examine the efficiency of a ceiling-mounted air curtain i...
