Abstract
The effects of convection flow on ignition of a paper sheet under super gravity condition were investigated by using a spin tester. The spin tester can change the gravity level from 1G to 15G The space under the paper sheet was changed to clarify the convection effect under the paper and bottom wall. Convection flow under the paper sheet was analyzed by PIV. As results, it was found that velocity of convection flow quickened with increasing the gravity level and with spreading the space under the paper sheet. Also ignition of paper sheet was promoted with increasing the flow velocity.
