Abstract Fluid boundary is quite common to be noted in engineering, for example, water tank, or the ocean. The tank wall could regarded as rigid wall. Besides, structures submerged water, hydrostatic pressure actually existes, and its effect important especially big level. In this work, hysrostatic are both accounted, natural frequency predicted cylindrical shell near with high pressure. Result...

Quentin Skinner is an intellectual historian known for his pioneering work on early-modern European political thought. He was educated at Bedford School and Gonville and Caius College, Cambridge. Author of such works as The Foundations of Modern Political Thought (1978) and Visions of Politics (2002) he served as the Regius Professor of History at the University of Cambridge, and currently as t...

This system aims to design and develop a prototype of an automatic for cleaning domestic cylindrical water tanks. The proposed includes simple mechanism with centrifugal force. Household tanks are supposed provide safe cleaning, gardening, cooking, drinking. majority the time coming into tank comes dust dirt particles. Over time, sludge or sediment may build up, contaminate cause illnesses in h...

multiphase impeller stirred tank reactors enhance mixing of reacting species used in a variety of chemical industries. these reactors have been studied based on computational fluid dynamics (cfd) that can be used in the analysis, design and scale up of these reactors. most of the researches done in this area are limited to single phase reactors, and a few remaining two phase flow investigations...

Cylindrical liquid storage tanks are considered as vital structures in industrial complex whose nonlinear dynamic behavior is of crucial importance. Some of these structures around the world have demonstrated poor seismic behavior over the last decades. There are several methods and techniques for rehabilitation and reducing damages in these structures which among them passive control devices, ...

This paper investigates the induced stresses in circular single deck roofs floating on seismically excited storage tanks. Equations of motion are derived using variational principle. Response of deck floating roofs is evaluated for two different classes of ground motions; near-source and long-period far-field records. Besides time histories and frequency contents for a specific tank, peak value...
