CFD analysis of human respiratory events in indoor environments

Abstract

This work aims to explore realistic scenarios of human respiratory events in an indoor environment. A FVM based 3D based multiphase solver, with an adaptive mesh refinement function, is used to solve the compressible multi-component fluid with an Eulerian-Lagrangian approach. Since recent studies claim that particles are assumed to remain airborne with very low diameters for longer periods, this thesis combines realistic scenarios of respiratory events and incorporates a user defined function that ceases evaporation of droplets smaller than a diameter of 5 mu m, together with a thermal difference between the person and the surroundings.
