Abstract

This study investigates the impact of solar charge controller (SCC) type on battery charging in solar-powered electric scooters (e-scooters). The research compared maximum power point tracking (MPPT) and pulse width modulation (PWM) controllers by monitoring average output power, current, and voltage every 10 minutes. Results showed that under stationary conditions, MPPT controllers delivered higher efficiency, generating 5.87 W of power compared to PWM's 5.05 W. This advantage persisted even during scooter operation, with MPPT controllers producing 4.91 W versus PWM's 4.31 W. Overall, the findings demonstrate that MPPT SCCs offer a more efficient solution for charging e-scooter batteries.

Abstract

This study delves into the optimization of polypropylene cutting board production through injection molding. Polypropylene, derived from propylene monomers, serves as the primary material. The injection molding process often leads to flash defects due to inadequate temperature and pressure settings. The research aims to discern the individual and interactive effects of temperature and injection pressure on the weight and surface area of the cutting boards. Experimental variations encompass temperature levels of 165°C to 175°C and injection pressures ranging from 25 Psi to 35 Psi. Data collection employs experimental methods, and analysis utilizes factorial and RSM approaches. Findings reveal that the lightest cutting boards result from the lowest temperature (165°C) and injection pressure (25 Psi), with an average weight of 105.6009 grams and a surface area of 21,158.3333 mm². In conclusion, both temperature and injection pressure significantly influence the weight and surface area of polypropylene cutting boards, providing valuable insights for enhanced manufacturing processes.

Abstract

The choice of control system for a flying electric vehicle/quadcopter is very important, especially for users who have never built or driven a flying electric vehicle. Electrical components which include the flight controller, ESC, battery, BLDC motor and other components have an influence in planning electric flying vehicles. Therefore, a BLDC motor control system is needed so that it can operate according to wishes and needs. The purpose of this research is to find out how the control system wiring diagram works, which includes the flight controller wiring diagram as the main flight control and the Electronic Speed ​​Control (ESC) wiring diagram as the BLDC motor speed controller. The choice of flight controller to operate the electric vehicle flight uses DJI Naza M V2 and electronic speed control uses a flier with a 3s-20s cell count configuration.

Abstract

This study investigates the impact of adding Zinc Oxide (ZnO) nanoparticles to radiator coolant to enhance the heat transfer performance of automotive cooling systems. The research explores the optimal concentration of ZnO nanofluids and examines operational conditions such as flow rates (7-11 lpm) and fluid temperatures (60°C, 70°C, and 80°C) to determine their effect on heat transfer performance. The results demonstrate that ZnO nanoparticles significantly improve the heat transfer coefficient, with the highest performance observed at a concentration of 0.35% ZnO and a temperature of 70°C. The optimal combination of flow rate (10 lpm) and temperature (70°C) resulted in a 62.86% increase in heat transfer compared to conventional coolant. This study provides valuable insights into selecting the optimal nanofluid concentration and operational conditions for improving vehicle radiator performance.

Abstract

This study aims to analyze and simulate the aerodynamic performance of the design of a training weapon grenade using the Computational Fluid Dynamics (CFD) method. CFD simulation allows the analysis of airflow around the grenade to identify the distribution of pressure, drag, and aerodynamic coefficients that play an important role in the efficiency of the grenade flight. The grenade design was tested under various conditions of speed and fin angle to understand their effects on stability and flight efficiency. The results of the simulation show that the variation of the mortar grenade with the fin position parallel to the launch angle has a fluid flow velocity of 84.1 m / s, the mortar grenade with the fin position tilted 2.5 has a fluid flow velocity of 82.7 m / s, and the mortar grenade with the fin position tilted 5 has a fluid flow velocity of 85.8 m / s from the data obtained, the inclination of the fin angle significantly affects the aerodynamic performance of the mortar grenade. This study provides insight that shifting the fin angle on the grenade can increase stability and minimize air resistance during flight.

Abstract

This research is to direct the mixture of air and fuel exactly to the top of the midpoint of the dome in the cylinder head. In addition, Squish Head also determines the character of the motorcycle. Moreover, what is very prominent in the initial pull is that if the compression ratio is denser, the pull is lighter.This study aims to determine the effect of changes in the slope angle of the squish head of 15, 17 and 19 degrees on compression and torque. In this study, experimental research is used with a quantitative method, where information that can be calculated and measured is factual because it is in the form of numbers. Researchers to get the data will conduct tests using the dynotest tool.Changes in slope of the squish head have an effect on the torque. At an angle of 15 degrees, torque is produced at 9.91 N.m at 6000 RPM engine rotation. At an angle slope of 17 degrees, the torque increases by 0.14 N.m to 10.05 N.m at 6000 RPM engine rotation. At an angle of 19 degrees, the torque increases by 0.17 N.m to 10.22 N.m at 6000 rpm.
