free surface sloshing of liquid in a rectangular tank induced by lateral excitation has been studied numericallyand experimentally in this paper. the numerical simulation is carried out based on the volume of fluid (vof) method that provides free surface extraction in such problem. a tank with transparent walls is used to free surface tracking in experimental study while the movement amplitude ...

Abstract: Chemical storage tank leakage in petrochemical wharf is a serious economic, environmental and safety problem. Risk assessment is an effective way to identify chemical storage tank hazards and provides a guide for accident prevention in petrochemical wharf enterprises. Based on the characteristics of chemical storage tank zone, this paper proposes a real-time relative risk assessment m...

the current study assesses the root causes of hydrogen blisters on low strength carbon steel equipment. for this purpose, some experiments including hardness test, non-destructive test (ndt), metallography, and fractograpghy are conducted. the microstructure of two blisters is assessed by means of optical microscopy and scanning electron microscopy (sem). the microstructural studies show that t...

In this experiment, thermal time constant measurements were taken from a system consisting of a heater, He gas, and a sensitive, low temperature resistance thermometer. The resistance thermometer [3] was made of a Ge film deposited on a GaAs substrate. The data from this experiment will be used to design a mass measurement system for hydrogen storage tanks in micro-gravity environments. INTRODU...

This paper studies the influence of material thermal properties on charging dynamics in a low temperature Thermal Energy Storage, which combines sensible and latent heat. The analysis is based small scale packed bed with encapsulated PCMs, numerically solved using COMSOL Multiphysics. PCMs studied are materials constructed typical (melting temperature, density, specific heat capacity (solid liq...

OBJECTIVE This study aimed to test the effects on sperm viability of transporting cryopreserved semen samples on dry ice. METHODS Twenty normozoospermic semen samples were cryopreserved and divided into five groups. The samples in Group 1 were immersed in liquid nitrogen throughout the experiment in cryogenic storage tanks; the cryopreserved straws in Group 2 were placed in a Styrofoam box co...
