Abstrak

Pengaruh aliran aksial terhadap aliran Taylor Vortex Turbulent dengan perpindahan kalor  dengan teliti dengan menggunakan metode numerik. Parameter geometri pada penilitian dengan radius ratio 0, 714 dan aspect ratio 10 dengan bilangan Reynold melingkar  antara 2596 sampai dengan 9087, kemudian  Aliran aksial  dengan temperatur pada silinder dalam (Ti) yaitu sebesar 50 °C  dan temperatur silinder luar (To) adalah 90 °C . Hasil penelitian menunjukan bahwa Aliran turbulen dalam aliran Taylor-Couette dengan aliran aksial dicirikan oleh struktur vortex yang kompleks dan tidak beraturan. Koefisien perpindahan kalor  pada kondisi konveksi di sekitar silinder dalam lebih tinggi dibandingkan dengan kondisi sedangkan untuk silinder luar kondisi diam dengan no slip condition. Peningkatan torsi akibat putaran silinder dalam aliran dipengaruhi oleh sel-sel vortex dalam aliran turbulen, yang juga menyebabkan kenaikan torsi gesekan.
