The possibility of employing internal wall as mass absorber in rectangular water storage tanks subjected to harmonic ground motion excitation is investigated in this paper. Internal walls are used in these tanks usually for service performance purposes, which could be used as mass absorber to control seismic demand on tank's exterior walls. Derivation of the response of the coupled system inclu...

Elevated tanks are important structures in storing vital products, such as petroleum products for cities and industrial facilities, as well as water storage. These structures have various types and are constructed in a way that a greater portion of their weight is concentrated at an elevation much about the base. Damage to these structures during strong ground motions may lead to fire or other ...

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...

Exploitation of solar energy for achieving low temperature is an active area of research at present owing to the concern over suitable alternatives to synthetic refrigerants and large electricity consumption by conventional vapour compression systems. Present work theoretically design and analyze the performance of a solar flat-plate collector-driven water-Lithium bromide absorption refrigerati...

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...

An evaluation of a variety of efficient water heating strategies for an all-electric single family home located in a mixed-humid climate is conducted using numerical modeling. The strategies considered include various combinations of solar thermal, heat pump, and electric resistance water heaters. The numerical model used in the study is first validated against a year of field data obtained on ...

Thermal energy for domestic hot water and heating use is stored in water tanks. Depending on the time of charging and the consumption the size of the storage tank has to be adjusted. In solar thermal systems, tanks sizes are typically around 0.3 – 0.5 cubic meter for single family houses and in case of seasonal storage systems up to several hundreds of cubic meters in district heating systems. ...
