The crashworthiness of helicopter fuel tank is vital to the survivability of the passengers and structures. In order to understand and improve the crashworthiness of the soft fuel tank of helicopter during the crash, this paper investigated the dynamic behavior of the nylon woven fabric composite fuel tank striking on the ground. A fluid-structure interaction finite element model of the fuel ta...

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 Hydromechanics Laboratory supports midshipmen education, as well as midshipmen, faculty and staff research, in the areas of naval architecture and ocean engineering. The laboratory facilities include a large towing tank (380-ft long, 26ft wide, and 16-ft deep), a small towing tank (120-ft long, 8-ft wide, and 5-ft deep), a coastal engineering wave basin (52-ft long, 48-ft wide, and 2-ft dee...

INTRODUCTION Law enforcement officers use conducted electrical weapons (CEW) such as the TASER X26 to control violently resistive subjects. There are no studies in the medical literature examining the effects of these weapons on the human stress response. This is the first study to compare the human stress response to conducted electrical weapons, oleoresin capsicum (O.C.), a cold-water tank im...

on the Columbia River plateau, a semiarid region in south-central Washington (Fig. 1), the Hanford Site At the Hanford Site, highly radioactive and chemically aggressive served as a plutonium production facility for nuclear waste fluids have leaked from underground storage tanks into the vadose zone. This paper addresses hydrogeological issues at the weapons from 1944 to the end of the Cold War...

The Atlantic Rainforest does not have a uniform physiognomy, its relief determines different environmental conditions that define the composition of its flora and fauna. Within this ecosystem, bromeliads that form tanks with their leaves hold water reservoirs throughout the year, maintaining complex food chains, based mainly on autotrophic and heterotrophic bacteria. Some works concluded that t...

Social interactions among multiple user groups of tank irrigation systems were studied to propose policies for sustainable management of tanks. Crop growers are the major competitors for water besides encroachers, fish and duck farmers. Existence of week property rights remained as the reason for the competition among users that subsequently led to conflicts. Conflicts aroused among user groups...

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...
