The influence of the incident spectral irradiance on electrical and thermal behaviour triple-junction solar cells has been investigated. A dependent model developed to calculate electric characteristics quantify heat power a multijunction cell. three-dimensional finite element analysis is also used predict cell's operating temperature cooling requirements for range ambient temperatures. combination these models improves prediction accuracy cells. convective transfer coefficient between...

The triple-junction solar cell is designed to exploit a wide range of the spectrum photons. These triple-layers consisting GaInP/GaInAs/Ge, it monolithically stacked, leading high conversion efficiency. To describe and understand it's operating behaviour, this paper presents performance analysis cell, based on estimation modelling. A model was developed determine characteristic cell. Hence, J-V curve characterising cells, which used optimise improve design cells. It has been discussed...

Thermochemical energy storage (TCES) has a vital role to play in future where 100 % of our domestic needs are generated by renewables. Heating and cooling represent 51 total consumption, as such contribute highly greenhouse gas emissions. As society, we have effective solutions for this the form renewable sources, primary two being: solar thermal heat wind power. However, one issue plagues these that is their intermittency. Specifically, seasonal deficit which represents significant surplus...

Synthetic jets are used for active flow control and enhanced heat transfer, typically generated by an orifice connected to a cavity with movable diaphragm actuator. Low-power operation is achieved matching actuator Helmholtz resonance frequencies. This brief communication presents analytical model derived from simplified gas dynamics, estimating the synthetic jet velocity deflection, based on pressure measurement. Model closure provided damping force in orifice, which agrees established loss...

The dynamic velocity range of particle image velocimetry (PIV) is determined by the maximum and minimum resolvable displacement. Various techniques have extended range, however flows with a wide (e.g., impinging jets) still challenge PIV algorithms. A new technique presented to increase over an order magnitude. multiple pulse separation (MPS) (i) records series double-frame exposures different separations, (ii) processes fields using conventional multi-grid algorithms, (iii) yields composite...

Results are presented for a concentrated solar photovoltaic and thermal powered membrane distillation (MD) system seawater desalination. Solar intensity data was input into mathematical model the energy out let temperature from calculated. The MD module tested fluctuating inlet temperature, as would be produced source. A maximum distillate flux of 3.4 l/m2h recorded, though this did not correspond to highest temperature. An observed delay in modules response fluctuations due mass unit....

A novel design concept of Flat Plate Solar Collectors (FPSCs) is conceived and developed by integrating with a freeze-tolerant (so-called ‘ice immune’) solution using flexible silicone tubing. It intended to directly run water in the solar thermal systems FPSCs instead expensive anti-freeze fluids, remove secondary heat transfer facilities (e.g. an extra tank buried exchanger). Successful development such kind collectors will enable reduction installed cost conventional without needing...

An impinging synthetic jet can attain heat transfer rates comparable to a continuous jet, without net mass input. However it needs forced cross-flow supply fresh cooling medium. The vectoring effect of adjacent jets allows directing the flow by changing phase between jets. This study uses two draw in air, while maintaining high impingement performance. experimental approach applies infrared thermography and particle image velocimetry quantify local convective field, respectively. profiles...
