This paper aims to illuminate the influence of hydrodynamic pressure generated in a water storage tank on behavior saturated sand that its support. Experimental tests were performed two cylindrical models using fabricated shaking table which consists flexible laminar shear box. The first model is partially full water, and second one with an equivalent load simulate without pressure. Three earth...

In any processes industry, process variables that need to be controlled are temperature, level, pressure and flow. This paper deals with an application of genetic algorithm to find the PID controller values to control the liquid level in the cylindrical tank. A process is identified as first order plus dead time model (FOPTD) and is validated. The intension of this paper is to obtain a minimum ...

cylindrical concrete tanks are commonly used in wastewater treatment plants. these are usually clarifier tanks. design codes of practice provide methods to calculate design forces in the wall and raft of such tanks. these methods neglect self-weight of tank material and assume extreme, namely ‘fixed’ and ‘hinged’ conditions for the wall bottom. however, when founded on deformable soil, the actu...

For the intermittence and instability of solar energy, energy storage can be a good solution in many civil industrial thermal scenarios. With advantages low cost, simple structure, high efficiency, single-tank system is competitive way (TES). In this study, two-dimensional flow heat transfer model cylindrical tank with water as fluid (HTF) developed, which effects time, velocity, height-to-diam...

This study investigates the buckling behavior of short cylindrical shells with hemi-spherical heads subjected to hydrostatic pressure. It is assumed that the length of the cylindrical part is smaller than or equal to its diameter while its material may be dif-ferent from that of hemispherical heads. Finite element analysis was used to seek out the effect of geometric parameters such as thicknes...

A stability analysis is presented of the hydrolysis of methyl isocyanate (MIC) using a homogeneous flow reactor paradigm. The results simulate the thermal runaway that occurred inside the storage tank of MIC at the Bhopal Union Carbide plant in December 1984. The stability properties of the model indicate that the thermal runaway may have been due to a large amplitude, hard thermal oscillation ...
