Abstract
In this thesis we will concern primarily with simulation of airflow pattern, carbon dioxide dispersion, and thermal comfort inside an educational classroom in Institute of Aviation Engineering and Technology, which is located on the second floor of the building of architecture, Hall 3201. An experimental investigation on the same classroom was accomplished which aims to validate the used CFD code and a Good the agreement is found among both predictions.These investigations included the measurements of relative humidity, and temperature, which were done using (Elcometer 319 Dewmeter gauge.The study is employed using CFD simulation techniques as embedded in the commercially available CFD code (FLUENT 19).The domain assembly case was finally discretized into 4,444,200 averaged tetrahedral elements. The thesis is keen to numerically investigate influence of changing the type of air outlet on the distribution of air and the thermal comfort for the occupants inside the teaching space and choosing the best design of air conditioning inside the classroom, this could be expressed concerning with only three different types of air outlet which are square diffuser, swirl diffuser, and round diffuser
