Abstract

The spraying system for grape cultivation requires uniform fluid distribution to ensure that water and plant-supporting solutions can be applied effectively. This study aims to evaluate the performance of a solar-powered overhead spraying system integrated with a solar panel cooling system through fluid flow analysis and the use of different nozzle types. The piping installation uses ½-inch PVC pipes, with pipe specifications determined based on JIS K 6742, while the design of the spraying system and evaluation of spray characteristics refer to ASABE S330.1. Testing was conducted by observing pressure, flow rate, and head loss in the piping network, as well as comparing the spray characteristics produced by full cone nozzle and misting nozzle. The test results indicate a pressure decrease along the piping network due to energy losses; however, the fluid can still be distributed to the final spraying point. The full cone nozzle produces a higher flow rate and a more uniform spray distribution, whereas the misting nozzle produces finer droplets. The results demonstrate that applying JIS K 6742 for pipe selection and ASABE S330.1 for the spraying system can support the design of an effective solar-powered grape spraying system with an integrated configuration.Keywords: overhead spraying system, fluid flow, head loss, nozzle, droplet

Abstract

One of the renewable energy sources with significant potential for further development is solar energy; however, its performance is highly influenced by surrounding environmental conditions. Several approaches can be implemented to optimize the electrical performance of solar panels, including determining the appropriate tilt angle and designing a surface cooling system. In this study, a 200 Wp solar panel was experimentally evaluated at tilt angles of 15°, 30°, and 45° and was equipped with a nozzle-based surface cooling system. The experimental results indicate that the 45° tilt angle produced the highest average output power of 209.775 W while the implementation of the surface cooling system improved the panel efficiency by approximately 13.06%, thereby enhancing the battery charging performance of a 12 V 45 Ah battery.Keywords: Solar panel, tilt angle, surface cooling system, output power, battery charging

Abstract

The accumulation of Polypropylene (PP) plastic waste has caused serious pollution that is difficult to mitigate using conventional methods. This study aimed to integrate the mechanical design of a pyrolysis system—specifically reinforcing the table frame and designing a secondary combustion cover—and to analyze how different combustion systems (open vs. closed) affect the characteristics of liquid fuel derived from 2 kg of polypropylene waste. Structural evaluation was conducted using SolidWorks simulations, while oil quality testing adhered to ASTM standards. Structural analysis results indicated that a 40 x 40 x 2 mm hollow steel frame could safely support a load of 103.04 kg (1,010.82 N) with a Factor of Safety (FOS) of 5.028. The redesigned 38 cm diameter combustion cover successfully minimized heat leakage, achieving an FOS of 1.268. Fuel testing revealed that the open combustion system yielded superior oil compared to the closed system, with Cetane Numbers of 31.5 versus 27.0, specific gravities of 780.9 kg/m³ versus 766.8 kg/m³, and kinematic viscosities of 1.465 mm²/s versus 0.975 mm²/s. Uniform heat circulation and airflow control proved crucial for breaking down carbon chains to produce stable liquid fuel.Keywords: pyrolysis, polypropylene, plastic waste, frame, combustion cover, SolidWorks Simulation, Factor of Safety
