The concept of direct absorption solar collector (DASC) was introduced in the 1970s. Multiple laboratory studies proved that nanofluid-based DASCs presented a fruitful alternative to conventional collectors. However, due environmental and cost limitations nanofluids, there are few records real-size operating field conditions. Filling gap, we report 5-month seasonal study for full-scale DASC with an eco-friendly low-cost nanofluid. Throughout experiments, competed commercial flat plate mounted exact location. results showed had average daily efficiency about 65.9%, while 57.7% 86.1%. most important parameters influencing flow rate extinction coefficient They alter by 9.2% 6.2%. Finally, article briefly notes technical economic features operation.

Solar energy is expected to play an important role in the decarbonization of and industrial sectors. Low medium temperature (<400 °C) solar thermal collectors have proved be a reliable solution supply heat decarbonize sector, with over 800 Heat for Industrial Processes (SHIP) plants put operation last decade. Governmental support policy key factor major CO2 emission reduction, which require improving efficiency reducing costs. Recent studies demonstrated potential nanoparticles enhance optical properties transfer fluids direct absorption (DASC). In DASC fluid absorbs volumetrically incident radiation, resulting more homogeneous distribution less losses than conventional surface collectors. this paper, current state-of-the-art SHIP installations presented, critical literature review dedicated nanofluid-based both concentrating non-concentrating provided. The findings challenges overcome toward promoting development applications are discussed.

Nanoparticle shape effects on MHD Cu–water nanofluid flow over a stretching sheet with thermal radiation and heat source/sink

International Journal of Modern Physics B, Год журнала: 2023, Номер 38(10)

Опубликована: Май 15, 2023

This study provides an insight into the effects of various nanoparticle shape factors on magnetohydrodynamic boundary layer flow and heat transfer over a stretching sheet. Choosing appropriate nanoparticles can control velocity transfer. A magnetic field is part momentum equation, radiation source/sink are energy equation. Equations governing problem converted nonlinear ODEs by similarity transformation. Afterwards, Runge–Kutta fourth-order scheme combined with shooting technique employed. porosity decrease velocity. Radiation both escalate temperature. The Eckert number also improve As volume fraction increases, Nusselt decreases skin friction increases. Among shapes considered in this study, platelet-shaped have best performance. According to studies we examined, results obtained consistent those previously published.

Solar energy is the most important source of thermal that comes from sun. This kind has enormous potential applications in fields technology such as photovoltaic panels, renewable power, solar light poles, and pumps used for water extraction. The era which we are living all about industrial sectors importantly sports car manufacturing. article presents a new way thinking heat transport analyses hybrid vehicles, by factoring Casson-Sutterby liquid with inclusion various effects like variable conduction, radiation, generation, tetrahybrid nanoparticles. To solve modelled equations regards to both momentum energy, another well-computational approach known Cash Carp method was used. wide variety factors on temperature, shear stress, velocity fields, well surface drag coefficient Nusselt number, briefly described illustrated form tables figures. It then found production, conductivity parameters insertion agglomerative tetrhybrid nanoparticles base fluid amplify transfer rate, it been shown performance increases terms transition. In comparison standard nanofluid, nanofluid effective medium transmission heat. From regression analysis, observed error number smaller 0.0151 case ε=1.5, ε=2.5. Relative percentage 4.62% generation Q=0.7 but maximum 15.8% radiation Rd=2.
