Fundamental study on noncontact measurement of viscosity using sound waves [in Japanese]

Ito Masayuki , Tai Hidekazu , Ueha Sadayuki , Kobayashi Tsutomu

一般に使用されている粘度計はいずれも供試液体と直接接触するので,測定に時間や手間が掛かり簡便性に欠ける。もし,非接触で測定できればこの問題はすべて解決し,リアルタイムで連続計測が可能となる。そこで,我々は低周波の音波とレーザ変位計を用いた非接触型の粘度計を検討し,広い粘度領域の測定が可能な非接触型粘度計を提案してきた。本研究では液体の粘度,密度,表面張力を考慮した共振現象に基づく簡単なモデルを適用 …
