The present study deals with the emhancement of thermophysical properties paraffin wax using Silver nanoparticles and to feasibility its application in a stepped solar still through an experimental approach. Along experimentation, yield, temperature water are predicted machine learning such as melting temperature, latent heat, thermal conductivity stability different concentrations (1 2%) investigated compared that without nanoadditives. was enhanced by about 35.71% 78.57% nano-additives 1% 2%, respectively. Three SS namely, wax, doped Ag nanoparticles, fabricated tested for climatic conditions Coimbatore, India. From results fresh generation, it is identified nanocomposite PCM nanoadditives 75.65% 114.81% respectively, while any energy storage. In order estimate amount can be produced each three stills, single adaptive neuro-fuzzy inference system (ANFIS) hybrid system-particle swarm optimizer (PSO) were used models. According statistical assessment, ANFIS-PSO model had greater level accuracy than standalone ANFIS. very high determination coefficient ranged between 0.981 0.995 which indicates capability predict yield stills.

This study aims at improving the desalination process of hemispherical solar still (HSS). A modified HSS (MHSS) design was developed, incorporating a 35 cm radius absorber to heighten vaporization area and sun exposure. The influence various factors on MHSS performance evaluated: wick material (jute cloth vs. cotton wick), rear reflectors for concentrated radiation, fan integration enhanced heat transfer, phase change (PCM) with silver nanoparticles (Ag) positioned beneath liner. itself achieved 96 % gain in productivity over HSS. Jute proved be more effective than cotton. equipped external exhibited significant 120 improvement productivity. Furthermore, within resulted 172 increase (11150 mL/m2⋅day compared 4100 HSS). Besides, enhancement (152 %) observed both PCM-Ag composite, yielding total daily freshwater production 10500 mL 4150 These findings suggest that optimized features, particularly use offers promising approach significantly improve performance.

Phase change heat storage has gained a lot of interest lately due to its high energy density. However, during the phase shift process, Change Materials (PCMs) experience issues such as low thermal conductivity, stability, leaking, and energy-storing capacity. that mimic or derive from nature can effectively offset shortcomings attributed. This work presents methodical overview synthesis, thermo-physical properties, comparison Thermal Energy Storage (TES) applications bio-derived biomimetic composite PCMs (BD/BM-CPCMs). Several studies have observed increase in conductivity up 950–1250 % for BD/BM-CPCMs, well great stability with no matrix leakage at an average temperature 150–250 °C. These types composites relative enthalpy efficiency 98.1 endure 200–1000 heating-cooling cycles on average. Additionally, enviro-economic aspects, numerical approaches transfer multivariate multi-objective optimizations technical, financial environmental standpoint using machine learning techniques underlying scopes BD/BM-CPCM are presented. It is necessary fabricate adaptable multifunctional harvesting future. With regard advancement substance functionalism, it show research use innovative effects like versatility, light conversion, electro-thermal anti-bacterial qualities real-world systems.
