Experiments have shown that the Jenike bunker outlet design method is accurate with respect to both the flow pattern (mass flow or funnel flow) and the minimum outlet required. Initial measurements of wall pressures in a 0.6-m-dia mass flow bunker were used to select a suitable measuring technique

Abstract: This research was conducted to record the fish species inhabiting Lake Ladik and its inlet and outlet streams between July 2003 and August 2004. Electrofishing equipment, fishing cast net, fisherman’s dip net, and fishing nets with different scales were used to catch fish samples. As a

Abstract Magnetic ballasts have limited the portability of mercury lamps for decades, while new electronic ballasts trade-off weight against cost and simplicity. We'll describe the lightest, most powerful, and economical UV equipment in the world today, for hand-held and floor curing

ABSTRACT The accessory facility of noise abatement is often confined for the necessity of equipment's maintenance and operation; therefore, how to ultimate the acoustic performance of mufflers within a limited space becomes an essential issue. This paper proposes an optimal design of a

ICT equipment more rationally for saving energy in commercial buildings, we have performed an energy audit of ICT loads at the School of Design and Environment, National University of Singapore, using smart power outlets. After a six-month period through which we have measured and analyzed

ABSTRACT This paper focuses on the application of CFD to the prediction of radial compressor aeroacoustics. It concentrates mainly on automotive turbocharger operations in the low mass-flow range where blade leading-edge and tip separation reduce the compressor performance and induce transient flow behaviour. Whereas the blade-passing is tonal and at high frequency, usually beyond the human hearing range, transience in the flow are turbulence-dominated, broad-band in nature, and in magnitude a significant source of aeroacoustics which appears well within the range of peak human hearing (1-5kHz). Other noise sources occur due to distortions in the flow upstream of the compressor face, and rotating stall. The simulation methodology enumerated here pays attention to all the above flow-induced aeroacoustics. Due consideration is given to turbulence modelling, to ensure that both the narrow-band and broad-band sources are directly resolved in the CFD. Appropriate discretisation practices are adopted, so as to capture both turbulent-convection and soundpropagation mechanisms. Pressure-wave non-reflective boundary conditions are applied to the computational boundaries to remove any artificial resonances in the domain. STAR-CCM+, the commercial CFD code used here, was previously benchmarked against experimental data for the same compressor under ideal installation conditions, then the compressor performance assessed under real installation conditions

hydropeaking at the outlet of the upper Aare River catchment is tested. Finally operation rules induced by the dynamic electricity market are simulated.

Abstract — The thermal environment of data centers plays a significant role in affecting the energy efficiency and the reliability of data center operation. A dominant problem associated with cooling data centers is the recirculation of hot air from the equipment outlets to their inlets, causing
