Spray aeration is a comparatively low-cost option to reduce trihalomethane (THM) concentrations in distribution system storage. The effect of spray on unregulated, toxic disinfection by-products was investigated bench-scale apparatus closed-tank and open-tank experiments. In the experiments, initially over 90% THMs, trichloroacetonitrile, chloropicrin were removed, while 36% dihaloacetonitriles...

In this work, CFD is used to simulate the flow in an existing thermal labyrinth located at the basement of a hospital building. This labyrinth is an underground channel equipped with water tanks to increase the thermal mass and reduce the heating and cooling demand of the building. Thermal energy storage in the water tanks is a complex heat transfer phenomena involving turbulent forced convecti...

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...

The cataclysmic events, which occurred at the Buncefield Oils Storage Depot in Hertfordshire on Sunday 11 December 2005, resulted in what is widely regarded as the largest explosion in Europe since the Second World War. This event placed the bulk storage industry in the spotlight, raising many yet unanswered questions. Accidents of this nature involving the catastrophic failure of tanks used fo...

AN ABSTRACT. This study presents a numerical evaluation of air flow and odor emission rate from an open manure storage tank. Odor emission rate is needed to facilitate the odor dispersion study and to compare different odor sources in terms of odor emission. The concentration at the manure surface, the tank dimensions, and wind speed were used to calculate air flow and the emission rate. The SI...

In this paper, the dynamic analysis of fuel storage tanks has been studied and some equations are presented for the created fluid waves due to storage tank motions. Also, the equations for finite elements of fluid and structure interactions, and boundary conditions dominant on structure and fluid, were researched. In this paper, a numerical simulation is performed for the dynamic analysis of a ...

The metal-organic framework beryllium benzene tribenzoate (Be-BTB) has recently been reported to have one of the highest gravimetric hydrogen uptakes at room temperature. Storage at room temperature is one of the key requirements for the practical viability of hydrogen-powered vehicles. Be-BTB has an exceptional 298 K storage capacity of 2.3 wt % hydrogen. This result is surprising given that t...

A Model Predictive Control (MPC) implementation was developed for a university campus chilled water plant. The plant includes three water-cooled chillers and a two million gallon chilled water storage tank. The tank is charged during the night to minimize on-peak electricity consumption and take advantage of the lower ambient wet bulb temperature. A detailed model of the chilled water plant and...

KNO3 was used as the phase change material (PCM), but its thermal conductivity is too low to transfer heat between the PCM and conduction oil efficiently. In this thesis, on the basis of the previous studies (Yong Li, 2015), the solar power generation efficiency is enhanced with high temperature interval (280°C—400°C), and the new composite which are composed by the SiC honeycomb (SCH) frame an...
