Kajian Numerik Efektivitas Upward Push-Pull Ventilation dalam Mencegah Penyebaran Virus Terbawa Droplet dengan Model Penguapan Droplet

Abstract

Disease transmission is mostly caused by airborne transmission of viruses. The risk of contracting the virus will be higher if someone spends time together and stays nearby in the same room with an infected person. Implementing social distancing is very important to limit the transmission of viruses. Still, due to the limited space in the industry, it is difficult to implement social distancing. Therefore, an air curtain is needed to protect workers without reducing their productivity. This Final Project discusses the upward pushpull ventilation effectiveness in preventing the virus carrier droplet transmission using droplet vaporization model. The analysis will be simulated using the Computational Fluid Dynamics (CFD) method. Based on the simulation, it shows that the air curtain has an under suction flow pattern with the largest nozzle blow discharge of 0.0793 m3/s and the largest nozzle suction discharge of 0.3969 m3/s which remains insufficient in preventing all droplets from entering the safety zone.
