Onset of nonlinearity in a two-dimensional thin shear layer
Autor: Seiichiro Izawa, Tatsuya Oku, Yu Nishio, Yu Fukunishi
Publikováno v: Fluid Dynamics Research. 54:025503
This study numerically investigates an early stage of nonlinear interaction for the better understanding of the onset of nonlinear behaviors. Two-dimensional shear flow is chosen as a canonical flow. When two disturbances of different wavenumbers sat

Abstract Erionite (ERI) zeolite has recently attracted considerable attention for its application prospect in the selective catalytic reduction of NOx with NH3 (NH3‐SCR), provided that the high‐silica (Si/Al > 5.5) analog with improved hydrotherm

Deformation mechanism of high-density polyethylene probed by in situ Raman spectroscopy
Autor: Yusuke Hiejima, Tatsuya Oku, Koh-hei Nitta, Takumitsu Kida
Publikováno v: Polymer. 58:88-95
The microscopic mechanism of high-density polyethylene under uniaxial drawing is investigated using in situ Raman spectroscopy. From the peak shifts of the symmetric and anti-symmetric C–C stretching modes, it is found that the load sharing on the

Design Guidelines for Dynamic Stability of Tainter Gates
Autor: Tatsuya Oku, Keiko Anami, Noriaki Ishii, Charles W. Knisely
Publikováno v: Volume 4: Fluid-Structure Interaction.
To ensure the long-term safe operation of newly constructed Tainter gates, methods of analysis and design criteria are needed in the design stage to assure the dynamic stability of any new Tainter gate. For this purpose, the present study provides a

Experimental Study of the Lubrication Mechanism for Thrust Slide Bearings in Scroll Compressors
Autor: Tatsuya Oku, Keiko Anami, Noriaki Ishii, Kiyoshi Sawai, Takashi Morimoto, Noboru Iida, Charles W. Knisely
Publikováno v: HVAC&R Research. 14:453-465
This study focuses on the effect that a pressure difference across the orbiting thrust plate of a thrust-slide bearing has on the improved lubrication of the bearing in scroll compressor applications. A thrust slide bearing model submerged in a refri
