Abstract

Blower industri sentrifugal merupakan komponen yang penting dalam berbagai aplikasi industri. Blower industri sentrifugal tersedia dalam berbagai ukuran dan bentuk geometri yang menentukan performansi dan karakteristiknya. Blower generik yang tersedia sering kali memiliki performa yang kurang optimal terhadap kebutuhan spesifik pengguna. Penelitian ini bertujuan untuk menganalisis dan merancang desain blower industri sentrifugal yang optimal untuk suatu kebutuhan spesifik dengan bantuan simulasi Computational Fluid Dynamics (CFD) dan metode Design of Experiment (DOE) Taguchi. Performa dari model blower generik saat ini diukur, kemudian dibandingkan dengan desain alternatif yang mengubah nilai parameter desain rasio diameter, jumlah bilah, dan sudut outlet bilah. Eksperimen dilakukan dengan menggunakan metode one factor at a time (OFAT) dan orthogonal array L9. Parameter performa yang dianalisis meliputi laju aliran, peningkatan tekanan, konsumsi daya, dan efisiensi. Pemilihan kombinasi desain optimal dilakukan dengan metode multi-criteria decision making berbasis weighted sum di mana bobot ditentukan sesuai preferensi pengambil keputusan menggunakan pairwise comparison. Hasil analisis menunjukkan bahwa kombinasi desain optimal adalah rasio diameter 0,5, jumlah bilah 12, dan sudut bilah 45°. Dibandingkan dengan model generik, desain optimal meningkatkan aliran sebesar 27.3%, meningkatkan tekanan sebesar 36.8%, mengurangi daya sebesar 2.5%, dan meningkatkan efisiensi dari 12.455% menjadi 21.688%. Analisis proses fabrikasi juga menunjukkan estimasi biaya fabrikasi model optimal tidak meningkat dibandingkan biaya fabrikasi model generik.

Centrifugal industrial blowers are essential components in various industrial applications. They are available in various sizes and geometric configurations which determine their performance and characteristics. The generic blowers models often deliver suboptimal performance for specific user requirements. This study aims to analyze and design an optimized centrifugal industrial blower design for a specific need with the help of Computational Fluid Dynamics (CFD) simulation and Taguchi Design of Experiment (DOE) method. The performance of the current generic blower model is measured, and compared to alternative designs that vary the design parameter values of the diameter ratio, number of blades, and outlet angle of the blades. Experimentation was carried out using the one factor at a time (OFAT) method and the L9 orthogonal array. The performance parameters analyzed include flow rate, pressure rise, power consumption, and efficiency. The optimal design combination was selected using a multi-criteria decision-making method based on weighted sums, where the weights were determined according to the decision maker’s preferences using pairwise comparison. The analysis showed that the optimal design consists of a diameter ratio of 0.5, 12 blades, and a 45°
blade angle. Compared to the generic model, the optimal design improved flow rate by 27.3%, pressure by 36.8%, efficiency from 12.455% to 21.688%, and reduced power consumption by 2.5%. Fabrication process analysis also indicated that the estimated production cost of the optimal model does not increase compared to the generic model.
