Comparative Performance Analysis of Various Flat Plate Solar Collectors Incorporating Spiral and Square Arrangement of Circular Type Riser Tube

Energy Science &Engineering, EarlyView.
Three flat‐plate collectors with spiral and square coiled riser tubes were tested and it was found that the spiral type provides the best results with a thermal efficiency of 66.98% for a mass flow rate of 0.4 kg/min. Riser tube geometry is a key factor in optimizing flat‐plate collector output.

Experimental Investigation on Steam Generation Performance of a Solid Thermal Storage‐Based Steam Production System

Energy Science &Engineering, EarlyView.
1. Against the backdrop of the dual carbon goals and the transformation of the energy structure, traditional coal and natural gas boilers struggle to meet the demand for economical and stable steam supply in small and medium‐sized enterprises. In response, this study proposes a solid‐state thermal storage steam production system, aiming to provide a ...

Hybrid Simulation–Machine Learning Surrogates for Coordinate‐Based Solar and Wind Energy Yield Assessment in Iraq: A Streamlit Decision‐Support Tool

Energy Science &Engineering, EarlyView.
This study integrates climatic simulations with machine learning to predict solar and wind energy across Iraq. Results show Random Forest excels for solar (R2 = 0.98) and neural networks for wind (R2 = 0.97), enabling a practical web tool for renewable energy planning. ABSTRACT Driven by the global shift away from fossil fuels, solar and wind resources
