Development of Miniaturised Fibre-Optic Laser Doppler Velocimetry for Opaque Liquid: Measurement of the Velocity Profile in the Engine Oil Flow of a Lubrication System
Autor: Tsutomu Tajikawa, Shimpei Kohri, Taiki Mouri, Takaichi Fujimi, Hiromasa Yamaguchi, Kenkichi Ohba
Publikováno v: Photonics, Vol 11, Iss 9, p 892 (2024)
This study developed a fibre-optic laser Doppler velocimetry sensor for use in opaque, high-temperature, and high-pressure fluid flows by inserting the fibre perpendicular to the main flow. The tip of the optical fibre was obliquely polished and chem

Development of Miniaturized Fiber-Optic Laser Doppler Velocimetry Sensor for Measurement of Local Blood Velocity
Autor: Tsutomu TAJIKAWA, Mitsuhiko TAKESHIGE, Wataru ISHIHARA, Shimpei KOHRI, Kenkichi OHBA
Publikováno v: Journal of Fluid Science and Technology, Vol 4, Iss 1, Pp 62-74 (2009)
A new miniaturized fiber-optic laser Doppler velocimetry (LDV) sensor has been developed, which is capable of measuring the local velocity in various semi-opaque and opaque fluid flows, particularly whole blood velocity in vessels. The sensor has a c

Deformation analysis of microcapsules compressed by two rigid parallel plates
Autor: Kenkichi Ohba, Kiyoshi Bando, Yuta Oiso
Publikováno v: Journal of Biorheology. 27:18-25
Alginate-poly(l)lysine-alginate microcapsules with a diameter of 200–300 μm were produced and subjected to compression experiments using two rigid parallel plates. The deformed shape was observed, and the relationship between the applied force and

Measurement and analysis of the shape recovery process of each erythrocyte for estimation of its deformability using the microchannel technique: the influence of the softness of the cell membrane and viscosity of the hemoglobin solution inside the cell

This study tried to evaluate the deformability of each erythrocyte by measuring the time constant of shape recovery just after the erythrocytes left the microchannels. We fabricated a microchannel array with a 5μm-square, 100μm-long cross-section o

Dynamic visco-elastic buckling analysis of an in vitro airway model: prediction of circumferential and axial buckling mode numbers
Autor: Kiyoshi Bando, Kenkichi Ohba
Publikováno v: Journal of Biorheology. 26:58-68
The purpose of the research reported here was to elucidate the mechanism of formation of the various lobes observed in asthmatic airways by both theoretical and experimental analysis employing an in vitro airway model. The rationale is that the eluci
