Numerical Study on Convective Heat Transfer in a Compartment Fire - I. Evaluation of Numerical Method and Natural Convection-

실내화재에 있어서의 대류열전달에 관한 수치연구 - I. 수치법 검증과 자연대류-

In a compartment fire, convective heat transfer dominates spread of the fire and smoke movement before flash-over occurs, and natural convection is very important in particular when there are no openings. The finite volume method with SIMPLE algorithm was applied to a square cavity similar to a compartment without an opening. The objectives of this study are to evaluate the method and to simulate natural convection from a hot body in the cavity. The results without the hot body showed an excellent agreement with those of previous studies. Streamlines, isotherms and Nusselt numbers were computed for different Rayleigh numbers.
