This research revealed control on Nano fluid temperature in the evacuated tube solar collector system, where fluids used ETSC as working to increase heating system thermal efficiency. Smart curtain was shadow and of or cooling condition which is moved by stepper motor programmed move through Arduino board using an artificial intelligence method such (PSO based PID) controller . Where curtain's ...

This paper presents the design, construction and performance evaluation of an efficient stand-alone PV- integrated solar clothes drying system for applications. The was constructed to reduce reliance on unsustainable electric dryers, which are high electricity-consuming appliances resulting in emission large CO2 amounts environment. All these developments were geared towards improving reliabili...

HITEC molten salt (7% NaNO 3 , 53% KNO 40% 2 ) has been identified as a suitable heat transfer fluid for concentrated solar power (CSP) systems, such parabolic trough collectors (PTC) and evacuated tube (ETSC). In order to optimize the flow performance of in ETSC, test rig was built conduct an experimental study, varying inlet outlet temperatures mass rates HITEC. Results show that loss ETSC is...

The thermal performance of the evacuated tubes solar collector (ETSC) for heating water with and without helical tape inside is evaluated experimentally. effect employing in tube on mean temperature storage tank efficiency has been investigated under winter ambient conditions AL-Mussaib city-Babylon-Iraq January February 2021. results showed an improvement using tubes. maximum meat that recorde...

The structural and physical stability of solid dispersions have not been adequately explored during spray drying manufacturing processes. In this study a wide range of compositions of naproxen/PVP-VA 64 (poly(1-vinylpyrrolidone-co-vinyl acetate)) and miconazole/PVP-VA 64 solid dispersions prepared by different laboratory spray dryers were collected from various selected locations and used to in...

Biomass, as a renewable source of energy, can be used in many industries to reduce their dependence on fossil fuels. However, due to the significantly high and varied moisture content of biomass, its use has several drawbacks, such as low total efficiency and process instability. Drying biomass before combustion or gasification can eliminate these drawbacks. Besides these benefits, there ar...
