Abstract

In this study a Fuel bed where surface fire spreads through is made to measure the data such as the flame height, radiation, spread rate and temperature distribution of Fuel bed. As experimental variables species of trees, wind velocities and slop are chosen. Fallen leaves of Quercus Variabilis (Q.V.) and Pinus Densiflora (P.D.) are used as fuel. Wind velocity is controlled by simply designed wind turnnel from 1 to 5 m/s. Slope of fuel bed is changed from $0^{\circ}$ to $30^{\circ}$. For the measurements of temperature distribution and spread rate total 35 of K-type 1.6 mm thermocouples are positioned as a lattice design. Radiant heat flow meters are used besides video camera and thermovision camera.

본 연구에서는 Fuel bed를 이용한 실험을 통하여 지표화 확산에 의한 온도 분포, 화염 높이, 복사열, 확산속도 등을 측정하였다. 실험 변수로는 수종, 풍속 및 경사도 등을 사용하였다. 수종으로는 침엽수종인 소나무 낙엽과 활엽수종인 굴참나무 낙엽을 사용하였다. 풍속은 터널식 방 구조에서 간이풍속 장치를 이용하여 1 m/s, 3 m/s, 5 m/s 풍속을 조절하여 실험하였다. 경사도는 Fuel bed의 기울기를 $0^{\circ}$, $10^{\circ}$, $20^{\circ}$, $30^{\circ}$로 변화시켜 가며 조절하였다. 온도 분포 및 확산속도를 측정하기 위하여 K-type 1.6 mm 열전대를 35개를 격자모양으로 배치하였다. 측정을 위하여 복사열량계를 사용하였으며 이외에도 비디오 카메라 및 열화상 카메라를 사용하였다.
