Stabilization of the linearized water tank system

In this article we study the so-called water tank system. In this system, the behavior of water contained in a 1-D tank is modelled by Saint-Venant equations, with a scalar distributed control. It is well-known that the linearized systems around uniform st ...

Uplift mechanics of unanchored liquid storage tanks subjected to lateral earthquake loading

Konstantinos Bakalis

Motivated by the seismic response of unanchored liquid storage tanks, their uplift mechanism under strong lateral loading is examined. Using three-dimensional finite element models, nonlinear static analysis is conducted to define the moment-rotation relat ...

Determination of variables influencing the effectiveness of disinfection of surface water used for human consumption in Costa Rica

Clara Barret

Disinfection of water for human consumption is a challenge to ensure that water is free of pathogens and pollutants while avoiding the formation of potentially harmful undesirable products. The establishment of disinfection facilities must take into accoun ...

Contained density currents with high volume of release

Mário Jorge Rodrigues Pereira Da Franca, Quentin Theiler

Contained density currents with high volume of release reflect against the boundaries of the reception environment commonly leading to oscillatory flow. These flows exist in sediment clarifiers, compromising their operations, and deposited signatures of co ...

Self-Replenishing, Wear-Resistant and Anti-Sticking Surfaces Based on Liquid Impregnation of Microstructured Mesoporous α-AI₂O₃ [Alpha Alumina] Matrices

Sriharitha Rowthu

Fabrication of wear-resistant omniphobic surfaces is a persistent scientific challenge and essential for various applications such as in paint industries, fluid transport, antifouling, reduction of friction drag on ship hulls, and stain resistant textiles. ...

Effect of radial base-plate welds on ULCF capacity of unanchored tank connections

Alain Nussbaumer, Gary Scott Prinz

The base of large steel liquid storage tanks can uplift during severe earthquakes, causing large inelastic rotations at the connection between the tank shell and tank base. While recent experimental studies indicate significantly higher connection rotation ...

Reversible chemical delithiation/lithiation of LiFePO4: towards a redox flow lithium-ion battery

Michael Graetzel

Reversible chemical delithiation/lithiation of LiFePO4 was successfully demonstrated using ferrocene derivatives, based on which a novel energy storage system - the redox flow lithium-ion battery (RFLB), was devised by integrating the operation flexibility ...

On the low-cycle fatigue capacity of unanchored steel liquid storage tank shell-to-base connections

Alain Nussbaumer, Gary Scott Prinz

Under strong earthquake motions, the liquid stored within large unanchored steel tanks can cause rocking and uplift of the tank base from the supporting foundation. Repeated rocking can lead to low-cycle fatigue fractures in the tank base-plate, and ultima ...

Experimental Determination of the Capacity of Wall-to-Base Connections in Storage Tanks

Alain Nussbaumer, Gustavo Cortes, Eric Lattion

Earthquakes around the world have affected many unanchored tanks used for storage of gasoline. When these unanchored tanks are subjected to strong motion, the moment generated at the base, by the mass of liquid contained in the tank, will cause partial upl ...

Experimental Study on the Seismic Behavior of Shell-Base Connections in Large Storage Tanks

Alain Nussbaumer, Gustavo Cortes

When an unanchored tank is subjected to strong motion, the impulsive mass of the contained liquid generates a moment which if strong enough could cause partial uplifting of the base plate. As the tank undergoes uplifting, the shell-base welded connection i ...
