Outline of Final Research Achievements

The advanced optical measurement techniques have been applied to internal compressible microflows. The following conclusions have been obtained.
(1) A supersonic expansion region peculiar to microduct flow has been observed. (2) Neither a normal shock wave nor a pseudo-shock wave appears in microduct flows. (3) A microduct flow changes gradually its supersonic state with the duct length under an underexpanded condition although a starting shock wave for large scale flows suddenly appears in a duct as its length exceeds a certain specific length. (4) For the compressible flows in the straight duct connected to a convergent nozzle, the length of in-duct choking, which is defined as a length between the sonic line and the duct exit, attains to the maximum at the Reynolds number of ~2000. (5) The temperature and pressure distributions on the duct wall (useful for estimating the local heat transfer on the microduct wall) have been successfully measured.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は,これまで未解明であったマイクロスケールの圧縮性流れに特有な現象を明らかにした点において学術的に意義が高い.また,本研究で得た知見は本流れをマイクロスケールの冷却装置として用いる場合の装置の設計指針となり得るので,社会的にも意義が高い.
