Contaminant transport in the aircraft cabin became one of the most vital issues that should be concerned, because
there are over 4.6 billion passengers choose travelling by aircrafts, as they are safe, comfortable, and fast. In addition,
aircrafts manufacturers aim to produce large aircrafts that are able to contain the highest number of passengers.
Airborne diseases, for example, SARS and Influenza are considered the most fatal diseases, which can be transported
in the cabin rapidly, due to the large number of particles or droplets in one cough or sneeze .Due to the velocity of
these particles, as a consequence their characteristics, airborne pathogens such as cough and sneeze can spread and
reach large number of passengers at one time. The present work aims to demonstrate simulations of cough droplets
that are produced from infected moving passenger using computational fluid dynamics simulation (CFD) .Dynamics
mesh and discrete phase models in ANSYS FLUENT program are used to identify the effects of these harmful
droplets on the other passengers inside the cabin. The results reveal that, cough droplet that were produced during the
movement of the passenger are extremely detrimental, as it could spread to a distance more than 4 meters along the
cabin, moreover, it negatively affect too many passengers in the cabin.
