The effect of injecting small bubble air into the water stream flowing in two spiral arrangement copper tube 15 m length, 0.012 diameter, and number coils were 11 has been investigated. inner surface solar collector was also painted with a matte black paint mixture nanomaterial (thermal dye 5% TiN). performance examined experimentally Babylon-Iraq, longitude (44.4 E) latitude (32.4 N) under bes...

Recent studies on increasing the thermal-hydrodynamic efficiency of solar air collectors have been carried out installation barriers various shapes surface absorber, and this method ensures a significant increase in energy collector. The transfer flow washing absorber from laminar state to an accelerated lumped is by installing obstacles. Installation main factor heat prolongs time barrier coll...

The amine regenerator of acid removal unit in South Pars Gas Complex, Assalouyeh, Iran was modeled. This model was fitted to assess the large scale columns and allow application of solar thermal energy for production of low pressure steam. Heat transfer fluids including Therminol oil, sulfur, or salt melt could be applied to yield thermal energy from a solar collector and to store and transfer ...

Solar energy is one of the most efficient forms renewable energy. air collectors are promising utilization solar The present study used unsteady three-dimensional Computational Fluid Dynamic (CFD) analysis to investigate heat transfer and fluid friction in with smooth v-corrugation absorber plates. studied parameters Reynolds number, height, pitch. Three number (500, 1000, 1500) values were thr...

In this work, the potential of magnetron sputtered magnesium uoride (MgF2) and MgF2 containing composite coatings for coloured solar collector glazing is investigated. Coloured thinlm interference coatings on the reverse side of the collector cover glass give solar collectors an aesthetic appearance, which facilitates their integration into the building’s envelope. Hereby, integration means tha...

The objectif of the present work is to determinate the potential of the solar parabolic trough collector (PTC) for use in the design of a solar thermal power plant in Algeria. The study is based on a mathematical modeling of the PTC. Heat balance has been established respectively on the heat transfer fluid (HTF), the absorber tube and the glass envelop using the principle of energy conservation...

Wet-collector systems, designed and operated for air-pollution control without concern for or con­ sideration of the stream-pollution effects of their liquid-borne wastes, may cause significant localized pollution of surface and ground water bodies. Wet­ collector systems can be designed with presently known technology to decrease contaminants in effluent outfalls to acceptable levels. Increasi...
