Abstract

Plasma arc cutting merupakan sebuah mesin yang digunakan untuk memotong berbagai jenis logam dan bahan lainnya dengan tingkat akurasi yang baik. Namun plasma arc cutting memiliki kelemahan yaitu memerlukan persediaan nozzle yang banyak untuk melakukan proses produksinya karena nozzle yang digunakan saat ini tidak mempunyai umur yang lama. Oleh karena itu, mencari pengaruh sudut inlet dan tinggi lubang nozzle lalu mensimulasikan secara termal dampak yang ditimbulkan oleh aliran plasma terhadap dinding nozzle untuk mengetahui nilai perubahan temperatur pada nozzle menjadi latar belakang penelitian ini. Desain nozzle dibuat menggunakan metode Computational Aided Design (CAD). Simulasi termal dilakukan menggunakan software Solidworks 2018. Hasil simulasi menunjukkan desain nozzle inovasi-2 memiliki nilai batas temperatur paling tinggi sebesar 2716 K lalu diikuti oleh desain nozzle inovasi-3 (2538 K), inovasi-1 (2250 K) dan komersial (2024 K). Perubahan sudut inlet dan tinggi lubang nozzle berpengaruh terhadap waktu penyerapan termal aliran terhadap dinding nozzle. Kata Kunci: Plasma arc cutting, desain nozzle, sudut inlet, computer aided design (CAD), simulasi termal, batas temperatur maksimal, software Solidworks 2018 Plasma arc cutting is a machine used to cut various types of metals and other materials with a high level of accuracy. But plasma arc cutting has the disadvantage of requiring a large number of nozzle supplies to carry out the production process because of its short lifespan. Therefore, this research was conducted to find out the effect of inlet angle and the height of the nozzle hole then simulate the thermal impact caused by the plasma flow on the nozzle wall to find out the maximum change nozzle temperature. Computational Aided Design (CAD) method was used to make the nozzle design. The thermal simulation was carried out using Solidworks 2018 software. The simulation results showed the innovation-2 nozzle design has the highest temperature limit value of 2716 K then followed by the innovation-3 nozzle design (2538 K), innovation-1 (2250 K) and the commercial one (2024 K). Changes in the inlet angle and the height of nozzle wall affect the thermal absorption time of the flow against the nozzle wall. Keywords: plasma arc cutting, nozzle design, inlet angle, computer aided design (CAD), thermal simulation, maximal temperature limit, Solidworks 2018 software
