Numerical Analysis of Air Flows for Korean Traditional House

Abstract

The present investigation is to examine the thermal behaviors of air flows inside Korean traditional house made of the construction materials transmitted. The research methodology is numerical predictions of air flows depend on the temperature distribution inside the house. The transient numerical experiments are performed along with the different house types, weather condition, and operating time of heating. Thermal properties of building units have been obtained by the parallel measurements and utilized in the numerical works. Consequently, the details of flows and temperature of air in the houses illustrate the thermal design of the traditional Korean house satisfy the requirements of human living. Main interest of the present investigation lies on the looking for optimum arrangements of contact region, such as a window and door are made of traditional materials, with the outside. The model shows equivalent thermal performance to the figure of the modern house using concrete structure and composite insulations. Observation and validation have been carried out by numerical predictions according to turning of the seasons. Details of flows both inside and outside of the house are prepared for the explanations of the merits of the traditional unit for Hanok. In addition, insulating flow patterns inside a room of Hanok are depicted for prefixed probe region.
