Abstract

Pompa sentrifugal vertical-inline banyak digunakan pada industri minyak dan gas karena memiliki konfigurasi yang kompak serta mampu diintegrasikan langsung dengan sistem perpipaan. Namun, keberadaan curved inlet sebelum impeler berpotensi menimbulkan distorsi aliran, distribusi kecepatan yang tidak seragam, serta peningkatan kerugian hidraulik yang berdampak terhadap penurunan performa pompa. Penelitian ini bertujuan menganalisis karakteristik medan aliran pada pompa sentrifugal vertical-inline menggunakan metode Computational Fluid Dynamics (CFD) serta mengevaluasi pengaruh modifikasi geometri inlet terhadap distribusi tekanan, distribusi kecepatan, pola streamline, head, dan efisiensi pompa. Simulasi dilakukan menggunakan ANSYS Fluent dengan pendekatan steady-state dan model turbulensi k-ω SST. Geometri dianlisis pada empat kondisi operasi yaitu 70%, 85%, 100%, dan 115% dari Best Efficiency Point (BEP). Hasil simulasi menunjukkan bahwa seluruh model menghasilkan distribusi tekanan dan kecepatan yang berbeda pada masing masing debitdesign.
