Parameter optimization and structural design of tuned mass damper for Shanghai centre tower
Parameter optimization structural design tuned mass damper Shanghai centre tower
2014/4/10
With a height of 632 m, Shanghai centre tower (SHC), located in Lujiazui district of Shanghai, will be the highest building in China. A tuned mass damper (TMD) system will be set in the upper part to ...
A numerical study of heat and mass transfer effects on an oscilaltory flow of a viscoelastic fluid with thermal relaxation
Finite difference method Oscillatory flow Heat transfer and Mass transfer
2010/11/25
We have studied numerically effect of heat and mass transfer on an oscillatory flow of a viscoelastic fluid with thermal relaxation. The dimensionless governing equations are solved using an explicit ...

The experiments on astronaut motions are difficult to conduct due to the limitation and high cost of constructing or simulating the microgravity environment of space. Therefore, the method of computer...
Sliding Mode Control of a Multi-Degree-of-Freedom Structural System With Active Tuned Mass Damper
Sliding mode control active tuned mass damper (ATMD) multi-degree-of-freedom structure
2009/10/13
In this study, a sliding mode control system is designed for a multi-degree-of-freedom structure having an Active Tuned Mass Damper (ATMD) to suppress earthquake or wind induced vibration. Since the m...
Mass Transfer Coefficients at the Stagnation Point with Submerged Impinging Multi-Jet Flow of Fluid Electrolyte
Multi-jets Disc distributor Nozzle hole Electrolytic cell Stagnation point
2009/10/10
This paper presents experimental results for the mass transfer coefficients in the impingement region of a multi-jet flow. A disc distributor containing ‘N’ nozzles produces multi-jets that interact i...
