Kertas kerja ini memberi tumpuan kepada penyiasatan berangka dan eksperimen pengaruh dua polimer (PA6 dan POM) ke atas tingkah laku arka semasa proses gerakan arka. Model matematik plasma arka udara 3 dimensi memandangkan ablasi dinding sisi dibina berdasarkan hidrodinamik magnetik (MHD). Dengan mengguna pakai pakej dinamik bendalir pengiraan komersial (CFD) berdasarkan kaedah volum kawalan, model MHD di atas diselesaikan dan taburan medan suhu, medan kepekatan, medan aliran dan medan potensi elektrik dalam ruang arka dikira. Hasil simulasi menunjukkan bahawa kepekatan wap di belakang lajur lengkok adalah lebih tinggi daripada di hadapan lajur lengkok kerana kewujudan "vorteks berganda" dalam ruang lengkok. Penggunaan polimer menyebabkan voltan arka maksimum meningkat 16.2% dengan POM dan 18.9% dengan PA6 dalam kes ini dan menyebabkan purata halaju arka meningkat 15.8% dengan POM dan 21.1% dengan PA6 dalam kes ini. Eksperimen juga dijalankan untuk mengkaji pengaruh polimer terhadap voltan arka dan kedudukan punca arka dalam ruang arka semasa pergerakan arka. Keputusan eksperimen membuktikan kesahihan penyiasatan berangka.

Abstract: This paper focuses on the numerical and experimental investigations of the influence of two polymers (PA6 and POM) on the arc behavior during arc motion process. The mathematical model of 3-dimentional air arc plasma considering the ablation of lateral walls is built based on magnetic hydro-dynamics (MHD). By adopting the commercial computational fluid dynamics (CFD) package based on control-volume method, the above MHD model is solved and the distribution of temperature field, concentration field, flow field and electrical potential field in the arc chamber are calculated. The simulation results indicate that the vapor concentration behind the arc column is higher than that in front of the arc column because of the existence of "double vortices" in the arc chamber. The use of polymers causes the maximal arc voltage increase 16.2% with POM and 18.9% with PA6 in this case and causes the average arc velocity increase 15.8% with POM and 21.1% with PA6 in this case. The experiments are also carried out to study the influence of polymers on arc voltage and arc root position in the arc chamber during arc motion. The experimental results prove the validity of the numerical investigation.
