Students’ Project: Aesthetic and Ergonomic Redesign of the Pneumatic Hammer

Every successful company aims to design successful products. The first phase of the design process, called product design, is therefore very important. Designers’ obligation is, for better break trough of the product on the market, to apply these demands and expectations to the developing product considering general, objective factors that have influence on design of specific product. Mechanica...

Slug tests in partially penetrating wells

A semianalytical solution is presented to a mathematical model describing the flow of groundwater inresponse to a slug test in a confined or unconfined porous formation. The model incorporates the effects of partial penetration, anisotropy, finiteradius well skins, and upper and lower boundaries of either a constant-head or an impermeable form. This model is employed to investigate the error th...

Water Hammer with Column Separation:

Column separation refers to the breaking of liquid columns in fully filled pipelines. This may occur in a water hammer event when the pressure drops to the vapor pressure at specific locations such as closed ends, high points or knees (changes in pipe slope). A vapor cavity, driven by the inertia of the parting liquid columns, will start to grow. The cavity acts as a vacuum, a low-pressure poin...

High Power LED Heat Dissipation Analysis via Copper Diamond Slug

junction temperature; ansys The emergence of high power light emitting diode as a novel electronic based light source is due to its vast advantage in terms of optical efficacy, low power consumption and enhanced life time. However, the performances of the LEDs are dependent on the junction temperature as it is inherited high heat production. Hence, proper evaluation of the junction temperature ...
