Air pollution in the environment is growing daily as a result of urbanization and population growth, which causes numerous health issues. Information about air quality environmental risks provided by pollutant data crucial for management. The use artificial neural network (ANN) approaches predicting pollutants reviewed this research. These methods are based on several forecast intervals, including hourly, daily, monthly ones. This study shows that ANN techniques contaminants more precisely than traditional methods. It has been discovered input parameters architecture-type algorithms used affect accuracy prediction models. therefore accurate reliable other empirical models because they can handle wide range meteorological parameters. Finally, research gap networks identified. review may inspire researchers to certain extent promote development intelligence prediction.

Fuzzy logic, introduced by Lotfi Zadeh in 1965, is a powerful method for modelling complex experiments. This study utilizes fuzzy logic to simulate and predict heat transfer double-pipe exchanger equipped with wavy inserts. The inserts, the form of twisted tapes, have varying twist ratios (TR=9, 7, 6). investigates range Reynolds numbers (Re) from 6000 18000, friction factors ranging 0.03620 0.08231, Nusselt (Nu) between 66.13 253.28. results different are compared ideal case. experimental indicate that highest occurs ratio 6, leading significant increase 162% number 36.21% rise factor scenario. In framework, input variables (Tr), temperature, (Re), while output (f) (Nu). demonstrates Mamdani inference system an exceptionally effective tool predicting outcomes, given its low error rate. Upon analysing data, it observed graphs plotting versus number, derived both data model, exhibit nearly identical trends margin just 3%. high level accuracy underscores reliability model replicating results.

This study investigated heat transfer and friction characteristics in a forced convection system using wavy twisted tape inserts with circular holes. The inserts, twist ratios (TR) of 8.5, 7.5, 6.5, were placed inside test pipe to create turbulent flow. tapes measured 700 mm length 18 width, while the had an outer diameter 35 inner 30 mm, section mm. Airflow rates adjusted achieve different bulk mean temperatures. Experimental data used develop new correlations for Nusselt number factor. Reynolds (Re) ranged from 4,000 14,000. Comparisons between varying pitches smooth tube showed that highest rate was achieved ratio 6.5.

This study experimentally investigates the influence of micro-channel height and width on heat transfer pressure drop within sinks, aiming to optimize their geometry for enhanced thermal performance minimized loss. Varying flow rates fluxes were applied different channel configurations determine coefficient Nusselt number. Results show that narrower (0.3 mm vs. 0.4 mm) taller (2.0 1.5 channels improved due increased surface area, but also drop. Higher Reynolds numbers (400-1200) flux (2.0-6.5 kW/m²) transfer, especially in channels, while roughness further at expense higher resistance. Optimized geometries effectively reduced sink temperature. research provides valuable insights designing efficient exchangers high-power electronics by balancing hydraulic performance. Major Findings: Micro-channel sinks demonstrate a significant enhancement when surfaces exhibit roughness. However, this comes cost system. To utilize cooling systems, careful optimization is essential strike balance between maximizing minimizing associated

Abstract The current research work involves the design and performance assessment of a solar still, which is conventional single‐slope basin‐type still (CSSBTSS) modified (MSSBTSS) under meteorological conditions Solan city, Himachal Pradesh, India (30.90° N, 77.09° E). individual combined effect different sample quantities sensible Himalayan Rambaan fibers (HRFs) mass latent paraffin wax (PW) A48 on MSSBTSS evaluated compared with CSSBTSS. use HRF material enhanced evaporation rate significantly improved daytime distillates. Besides, masses PW filled inside aluminum tubes nocturnal For analysis, three cases have been considered are, namely: Case 1, HRFs (MSSBTSS‐HRF); 2, (MSSBTSS‐PW); 3, (MSSBTSS‐HRF‐PW). results showed that maximum thermal efficiency for Cases 1 2 was by 30.02% 42.41% five 5000 g PW. energy 90.71% gain 45.16% over economic analysis concluded cost per liter distillate yield produced using MSSBTSS‐HRF‐PW CSSBTSS ₹1.5 ₹1.6, respectively. These outcomes great potential approach towards enhancing overall cost‐effectiveness still.

Predicting PV system electricity output is necessary for daily operational management and annual power planning when integrating solar collector-based photovoltaic (PV) stations into micro grids. Tilting the panels at ideal angle to maximize energy capture station production.
