Abstract

This study aims to analyze the effect of variations in nozzle spacing and inlet air velocity on the vacuum pressure and flow velocity distribution in a jet ejector vacuum pump. The method used is a numerical simulation based on Computational Fluid Dynamics (CFD) to obtain a detailed picture of the fluid flow characteristics in the system. The variations in nozzle spacing studied include 14 mm, 16 mm, and 18 mm, while the inlet air velocity is varied at 10 m/s, 15 m/s, and 20 m/s. The simulation results show that increasing the nozzle spacing tends to reduce the pressure on the venturi, thereby increasing the vacuum effect, with optimal conditions obtained at a distance of 18 mm and an inlet velocity of 10 m/s. Under these conditions, the pressure in the tube reaches the lowest value compared to other variations. However, increasing the inlet air velocity actually causes an increase in pressure in the tube due to turbulence and backflow, thereby reducing or even eliminating the vacuum effect at velocities of 15 m/s and 20 m/s. Overall, the performance of a jet ejector is greatly influenced by a combination of geometric and operational parameters.

Abstract

Fenomena sudden enlargement pada sistem perpipaan merupakan salah satu penyebab utama terjadinya head loss yang dapat menurunkan efisiensi aliran fluida. Penelitian ini bertujuan untuk menganalisis pengaruh variasi bentuk sudden enlargement terhadap kehilangan energi pada aliran fluida laminar dengan menggunakan tiga variasi geometri, yaitu Square Edge, Rounded Edge, dan Projecting Edge. Pengujian dilakukan pada pipa berbahan akrilik menggunakan manometer U sebagai alat ukur tekanan dengan dua titik pengukuran, masing-masing pada diameter 12,7 mm dan 50 mm. Dua tingkat laju aliran udara diuji, yaitu 6 L/menit dan 4 L/menit. Data tekanan yang diperoleh diolah untuk menghitung kecepatan aliran dan head loss menggunakan persamaan dasar fluida. Hasil penelitian menunjukkan bahwa bentuk geometri memiliki pengaruh signifikan terhadap besarnya head loss. Pada laju aliran tinggi (6 L/menit), geometri Square Edge menghasilkan head loss terendah, sedangkan Rounded Edge memberikan performa optimal pada laju aliran rendah (4 L/menit). Geometri Projecting Edge secara konsisten menghasilkan head loss tertinggi pada kedua kondisi. Temuan ini menunjukkan bahwa pemilihan geometri sudden enlargement harus disesuaikan dengan kondisi operasi sistem. Penelitian ini diharapkan dapat menjadi referensi dalam perancangan instalasi perpipaan yang lebih efisien dan mendukung optimasi energi pada sistem transportasi fluida.

Abstract

This study presents the design and structural verification of a compact meatball-forming machine that integrates an Arduino Uno–based operator protection system. A redesigned 500×500×1011 mm frame made of 20×20×1.5 mm hollow steel was modeled in SolidWorks 2024 and evaluated using finite element analysis (von Mises stress, displacement, strain, and safety factor) under an applied load representing a 30 kg operating condition. To reduce assembly complexity, two alternative concepts were assessed using Design for Assembly (DFA), and the most efficient configuration was selected for detailed development. The safety subsystem employs an HC-SR04 ultrasonic sensor facing the operator zone; when the detected distance falls below 10 cm, the controller triggers a warning indicator and enables protective control actions. The final concept achieved higher DFA efficiency (18%) than the initial concept (16%) while reducing material use and overall footprint. Structural simulations indicate a peak von Mises stress of 163.6 MPa, below the 250 MPa yield strength of ASTM A36 steel, a maximum displacement of 1.002 mm, and a minimum safety factor of 1.528, confirming adequate stiffness and margin against yielding. The proposed design combines adjustable forming via an iris mechanism with servo-driven cutting to improve process consistency while embedding real-time proximity sensing to enhance occupational safety.

Abstract

General Background: Automotive development increasingly emphasizes component material selection and manufacturing methods to optimize engine performance. Specific Background: Pistons are critical engine components whose production route, particularly casting and forging, may influence power and torque characteristics. Knowledge Gap: Although many studies discuss piston materials and engine performance separately, direct comparative experimental evidence between casting and forged pistons under identical operating conditions on the Yamaha Jupiter Z 2007 remains limited. Aims: This study aims to analyze the differences in power and torque generated by standard, casting, and forged pistons using dynotest measurements at 2000, 4000, 6000, and 8000 RPM. Results: The results indicate that forged pistons produced the highest overall performance, with average torque reaching 13.32 Nm at 2000 RPM and average power reaching 11.2 HP at 6000 RPM. Casting pistons occupied an intermediate position, while standard pistons consistently produced the lowest values. At high engine speed, forged pistons maintained better performance stability than casting and standard pistons. Novelty: The study directly compares three piston types within the same motorcycle platform while also relating performance differences to piston mass variation, where forged pistons showed the lightest weight. Implications: These findings indicate that piston manufacturing type is closely associated with engine output, and forged pistons offer stronger potential for applications requiring higher power and torque performance. Keywords: Forged Piston, Casting Piston, Engine Performance, Power and Torque, Dynotest Key Findings Highlights Forged pistons produced the highest output across most engine speed ranges. Peak engine capability was observed around 6000 RPM before declining at 8000 RPM. Lower piston mass was associated with stronger high-speed performance stability.
