Dynamic stability of submerged pipelines
نویسندگان
چکیده
The paper considers the dynamic stability of submerged pipelines with denudation and sagging depending on their stiffness river flow rate. hydrodynamic force frequency natural vibrations pipeline are calculated at actual critical length sagging. It is shown that external applied to sagged corresponding critical, coincides vibrations. found loss occurs in resonant region vibration due increased variable force.

We study the stability of passive motion of a fish model. The (articulated body) fish model accounts for the finite dimensions of the fish, its bending stiffness (via the torsional springs at the joints), the unsteadiness of the flow (via the added mass effect) but it does not take into consideration vortex shedding from the trailing edge of the fish. The stability analysis shows that there is ...

The SLS and RLS estimation methods proposed for average power estimation are linear, unbiased, and do not assume any distribution for the input sample data. The experimental results indicate that the least square estimation algorithms converge up to 24 times faster than the Monte Carlo and DIPE for random inputs. ACKNOWLEDGMENT The authors would like to thank the reviewers and the associate edi...

Objective: Investigations were carried out to isolate bacteria from saline-alkali soils and determined optimized alkaline protease activity and stability produced by a wild strain of bacillus sp. in submerged fermentation (SMF). Methods: Optimum temperature for enzyme activity in the crude extract was 40 ◦C at a pH between 8.0 and 9.0. The studies on pH stability showed that the enzyme...
