Instabilities in viscoelastic flow past a square cavity

Journal of Non-Newtonian Fluid Mechanics, 2000
Abstract Elastic flow transitions in viscoelastic flow past a square cavity adjacent to a channel are reported. The critical conditions for the onset of flow transitions and the qualitative and quantitative characterization of the secondary flows generated by the instability have been examined using streakline photography and instantaneous pressure ...

Square ring laser diode with MMI coupler cavity

IEEE Photonics Technology Letters, 1997
A square ring laser diode is designed and fabricated in which a multimode interference 3-dB coupler operates as an output coupler and a ring resonator simultaneously. This merged structure allows a shorter cavity length and a lower loss in the output branching. Lasing in the ring cavity is confirmed and the spectra are also measured.

Global Modes and Control in a Square Cavity

5th AIAA Theoretical Fluid Mechanics Conference, 2008
The global stability of flow over a square cavity is investigated using numerical simulations combined with iterative Krylov subspace schemes. Balanced modes are computed using the balanced POD method and a reduced-order system is determined. This reduced system then forms the basis for the design of control strategies to suppress the vortical ...
