The leakage process simulation of a Natural Gas Liquid (NGL) storage tank requires the simultaneous solution of the NGL’s pressure, temperature and phase state in the tank and across the leak hole. The methods available in the literature rarely consider the liquid/vapor phase transition of the NGL during such a process. This paper provides a comprehensive pressure-temperature-phase state method...

The article describes the actual work’s numerical analysis for unit joining walls to bottom of vertical cylindrical tank 50 thousand m 3 . Having analyzed relevant stress-strain state tanks different types finite element model. Research carried out with a wall on rigid base. Features should include effect various loads: static, dynamic, cyclic, corresponding normal operation. load pressure liqu...

dynamic behavior of ground supported cylindrical storage tanks (cst) is of crucial importance because of its applications in industrial complexes. seismic behavior of tanks is greatly affected by the height to diameter ratio, fluid height and fluid type. five csts with different height to diameter ratios, three csts with the same height and diameters but various fluid heights and one cst with t...

Buckling of imperfect thin shell tank which is subjected to uniform axial compression is analyzed. The effect of internal pressure on the stability of a shell tank filled with a homogeneous-heterogeneous liquid was considered. Investigation of the liquid nature effect on reduction of the shell buckling load is performed by using the finite elements method. Calculating results in terms of analyt...

In this study, the liquid sloshing in a cylindrical tank considering soil–structure interaction and undergoing horizontal excitation is investigated analytically. Multiple rigid annular baffles are positioned on wall to mitigate sloshing. Firstly, combined with subdomain partition method for sloshing, complex domain partitioned into simple subdomains single condition boundary. Based continuity ...

This Brief Report is devoted to the study of the solitary surface wave rotating in the azimuthal direction, arising during water drainage from a cylindrical reservoir, when shallow flow conditions are reached. The linear dependence between the wave speed and its amplitude is shown to be similar to that expected from the classical Korteweg-de Vries equation.

A conical tank in which the diameter changes with the tank height, allows the use of feedback control used in complex nonlinear systems, such as adaptive control. This project modified an existing system of two interacting tanks by inserting a removable solid cone into one of the tanks. This modification created two new nonlinear configurations, one of which had a discontinuity. Optimal control...

In order to analyze the changing rules of temperature and pressure of the gas-liquid coupled field of LPG (Liquefied Petroleum Gas) tank under fire, the application of the wavelet finite element method on it is studied in depth. First, the research achievements of thermodynamics response of the LPG tank under fire and the wavelet finite element theory is summarized. Second the temperature-press...
