Abstract

The fluid circulating in the iPWR uses two working fluids, the primary fluid as a reactor coolant which delivers heat to the secondary fluid to generate steam. The secondary working fluid flows in the steam generator pipe without direct contact with the primary working fluid. The cooling process of the primary working fluid can be simulated using the Computational Fluid Dynamics (CFD) method to obtain the temperature distribution in the reactor core. So, this research will focus on analyzing the temperature distribution of the first working fluid in the iPWR reactor core using the CFD method. Simulation of the primary fluid flow being heated or cooled under normal conditions to reach the upper and lower temperature targets by adjusting the fluid flow speed used. Under normal and/or mal function conditions, the water temperature does not reach saturation. However, this research has not considered the material condition and pressure when the auxiliary tools are disabled.

Abstract

Abstract: This research aims to model and analyze the performance of a vertical axis wind turbine (VAWT) of H-Rotor type as an alternative renewable energy source for street lighting in Pandeglang Regency. The study employed both mathematical analysis and Computational Fluid Dynamics (CFD) simulation using ANSYS CFX. Variations of design parameters included blade chord length, blade number, and pitch angle with NACA 0015 as the blade profile. The average wind speed of 4.25 m/s from Carita, Pandeglang, was used as input. The results showed that the optimal configuration (chord 6 m, 4 blades, pitch angle 15°) produced a theoretical torque of 352.8 Nm and power of 486 W, while CFD simulation yielded torque of 306.1 Nm and power of 422–454 W. The error margin of ±15% indicates the validity of the simulation model. With three turbines connected in parallel, an effective capacity of 1200 W can be achieved to support street lighting. This study concludes that the H-Rotor VAWT is feasible as a renewable energy solution for low wind speed regions. Keywords: VAWT, H-Rotor, torque, CFD, renewable energy, Pandeglang. Abstrak: Penelitian ini bertujuan memodelkan dan menganalisis kinerja turbin angin sumbu vertikal (VAWT) tipe H-Rotor sebagai sumber energi terbarukan alternatif untuk penerangan jalan di Kabupaten Pandeglang. Metode penelitian menggunakan analisis matematis dan simulasi Computational Fluid Dynamics (CFD) dengan perangkat lunak ANSYS CFX. Parameter desain yang divariasikan meliputi panjang chord, jumlah bilah, dan sudut pitch, dengan profil bilah NACA 0015. Data kecepatan angin rata-rata 4,25 m/s diambil dari Kecamatan Carita, Pandeglang. Hasil penelitian menunjukkan bahwa konfigurasi optimal (chord 6 m, 4 bilah, sudut pitch 15°) menghasilkan torsi teoritis 352,8 Nm dengan daya 486 W, sedangkan hasil simulasi CFD menunjukkan torsi 306,1 Nm dengan daya 422–454 W. Selisih hasil ±15% menunjukkan validitas model simulasi. Dengan tiga unit turbin paralel, dapat dihasilkan kapasitas 1200 W untuk kebutuhan penerangan jalan. Penelitian ini menyimpulkan bahwa VAWT H-Rotor layak diterapkan sebagai solusi energi terbarukan pada daerah dengan kecepatan angin rendah.Kata kunci: VAWT, H-Rotor, torsi, CFD, energi terbarukan, Pandeglang.
