Outline of Final Research Achievements

In the present study, the methodology was pursued for the energy conversion from continuous laser to high speed gas flow via micro/nano scale solid materials. After surveying several materials, we focused on using a low density porous material of carbon fiber, whose typical scale is micro scale. In the experiment, the energy conversion efficiency was found 20% at the maximum, and the maximum gas temperature was as high as 1500K. However, theoretical estimation suggests that the energy conversion can be increased up to 80%.
