Abstract
The demand for efficient energy conservation methods is growing amid rising fuel costs and greenhouse gas emissions. Phase change materials are essential for thermal energy storage, and silica aerogels, when combined with these materials, are particularly effective for insulation. This study presented a novel analysis of how various magnetic field strengths (ranging from 0 to 0.5 Tesla) affected the thermal behavior of a nanostructure composed of silica aerogel, paraffin, and CuO nanoparticles in a cylindrical tube. Using molecular dynamics simulations, we examined the magnetic field’s effect on key thermal properties, including density, temperature, heat flux, thermal conductivity, and the charging and discharging times. Results indicate that increasing the magnetic field strength to 0.5 Tesla led to a decrease in maximum density from 0.1385 to 0.1372 atoms/ų. Additionally, the maximum velocity increased to 0.0142 Å/fs, while the maximum temperature and heat flux rose to 646 K and 72.13 W/m 2 , respectively. The observed charging and discharging times were 5.91 ns and 8.52 ns, with stronger magnetic fields expediting the charging phase. These findings offer valuable insights into optimizing thermal energy storage systems through magnetic field modulation. • The research aimed to explore how different strengths of a magnetic field affect the behavior of a tube made from silica aerogel and paraffin. • computer simulations were used to analyze the properties and temperature changes of the particles within the tube. • The study specifically looked at how increasing the strength of the magnetic field influences various factors • when the magnetic field strength was increased, the maximum density decreased

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
