Twin Plate Weir: A Flow Measuring Device (TECHNICAL NOTE)
For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...
متن کاملA nanophotonic solar thermophotovoltaic device.
The most common approaches to generating power from sunlight are either photovoltaic, in which sunlight directly excites electron-hole pairs in a semiconductor, or solar-thermal, in which sunlight drives a mechanical heat engine. Photovoltaic power generation is intermittent and typically only exploits a portion of the solar spectrum efficiently, whereas the intrinsic irreversibilities of small...
متن کاملLarge-scale ultrasonic cleaning system: Design of a multi-transducer device for boat cleaning (20kHz).
The present study is part of a global project which consists in the development of an automatic cleaning station for immersed boats (cockle, ninepin, etc.) in a self-service mode, associating an innovative ultrasonic device for cleaning with a specific water treatment. The originality of the process is that cleaning is performed by three transducers operating simultaneously at low frequency and...
متن کاملAddendum: A nanophotonic solar thermophotovoltaic device.
Eq. 1 in this Letter (and also, Eq. 1.133 in ref 2) represents the temperature required for the maximum of Planck’s distribution expressed in units of wavelength to match the bandgap energy. However, the energy at which the maximum occurs depends on whether we consider energy flux per unit frequency range or per unit wavelength range3,4. A more appropriate approximation matches the maximum of P...
متن کاملDry Cleaning of Sugarcane - a Review
In the light of increasing public pressure to minimise environmental pollution, green cane harvesting will probably soon become the norm worldwide. The effects of delivering and crushing green cane, which contains all of the associated extraneous matter, on the cost of production and the quality of sugar are well known. In consequence of these effects the different options for dry cleaning the ...
