For crews' safety, we need to investigate combustion characteristics of electric wire insulation burning under micro-gravity condition and establish a criterion for material selection. In electric wire burning under micro-gravity condition, the copper wire with very large heat conducivity is considered to play an important role. The mechanism of electric wire insulation burning is supposed to consist of the following two processes. (1) At the coating-burned-out wire part, the spherical flame contacts with the copper wire and heats it and intensive gasification occurs at the edge of coated wire part. (2) The gasified fuel diffuses radially to meet oxygen, forming a spherical flame. Our calculations confirm that the heat feedback via copper wire is very crucial to whether self-sustained burning is attained or not after the cease of heating, and that it brings about phenomena that are peculiar to electric wire insulation burning under micro-gravity condition.}, pages = {1487--1493}, title = {微小重力場における被覆電線の燃焼の数値計算}, volume = {67}, year = {2001} }
