Natural ventilation design of UNHCR family tent / Karen Bong Hui Ju

UNHCR Family Tent is one of the most common emergency shelter that being used in most of the refugee camps and during emergency cases. Most of people are living in the UNHCR Family Tent in a long period of time either in a few years or a decade. Most of the publications research nowadays that are related with refugee shelters, discussing more on the tensile strength and durability of the shelter instead of the natural ventilation. In this research, four case studies on different locations of openings like window openings, door openings and roof openings are studied in order to investigate and discuss the effectiveness of those openings in helping natural ventilation on the UNHCR Family Tent. As the temperature of the UNHCR Family Tent is related and correspond to the natural ventilation, this research study also discuss on the temperature of the UNHCR Family Tent in order to determine whether the UNHCR Family Tent is comfortable for living purposes This research is being done by using ANSYS Fluent, a Computational Fluid Dynamic software that simulate the similar situation of the UNCHR Family Tent. The simulation program is easy to be used and handle with precise details on the data. The data collected are mainly focus on the velocity pathlink, velocity magnitude and temperature. After simulating on the data, the case studies are being compared in order to find out the best situation and improvement that can be done by simply changing the openings. The results that are gained from the research shows that by adding in more openings at different locations will increase the velocity magnitude of the air that are entering into the UNHCR Family Tent and decrease the temperature of the tent
