Southwest Jiaotong University: Open kitchen design is becoming popular in small units in high-rise residential buildings. This design increases the possibility that fires originating in the cooking area would spread beyond its origin. Effect of cabinet properties and wind on the fire hazards of open kitchen is numerically studied. It is found that if there are combustible items adjacent to the cooking area it helps the fire to spread giving a big fire and the wind may cause the fire spread vertically along the building exterior wall.
