Abstract
Shell and tube heat exchangers are essential components in various industries for transferring thermal energy between two fluids with significant temperature differences. Pressure drop on the shell side is a key factor in designing an optimal heat exchanger. This study aims to optimize the heat exchanger design by implementing helical baffles to reduce stagnant zones and pressure drop on the shell side. The Particle Swarm Optimization (PSO) method was used to determine the optimal parameters, resulting in a helical baffle angle of 26.2032 degrees and a baffle spacing of 491.6579 mm. This configuration achieved a total heat transfer coefficient of 33.5699 W/m²K and a pressure drop of 0.0699 kPa, showing a 77.42% improvement compared to the segmental baffle design. This design maintains the heat transfer capacity at 789.010 kW while reducing stagnant zones, which helps slow down fouling formation. Validation using HTRI software confirmed the consistency between simulation results and validation data, proving that the implementation of helical baffles effectively enhances the operational efficiency of the heat exchanger. Thus, this design has the potential to be applied across various industries to ensure optimal heat exchanger performance over time. Keywords: Shell and Tube; Helical Baffle; Heat Transfer Coefficient; Pressure Drop; Particle Swarm Optimization (PSO) Heat exchanger tipe shell and tube merupakan komponen penting dalam industri untuk mentransfer energi panas antara dua fluida dengan perbedaan suhu yang signifikan. Penurunan tekanan pada sisi shell menjadi faktor utama dalam mendesain heat exchanger yang optimal. Penelitian ini bertujuan untuk mengoptimalkan desain heat exchanger dengan menerapkan helical baffle guna mengurangi zona stagnan dan pressure drop yang terjadi pada sisi shell. Metode Particle Swarm Optimization (PSO) digunakan untuk menentukan parameter optimal, yaitu sudut helical baffle sebesar 26,2032 derajat dan jarak antar baffle 491,6579 mm, yang menghasilkan koefisien perpindahan panas total sebesar 33,5699 W/m²K serta penurunan tekanan sebesar 0,0699 kPa, dengan perbaikan 77,42% dibandingkan desain segmental baffle. Desain ini mampu mempertahankan kapasitas perpindahan panas pada 789.010 kW sambil mengurangi zona stagnan, sehingga dapat memperlambat laju fouling. Proses validasi menggunakan perangkat lunak HTRI menunjukkan kesesuaian antara hasil simulasi dan validasi, membuktikan bahwa penerapan helical baffle efektif dalam meningkatkan efisiensi operasional heat exchanger. Dengan demikian, desain ini berpotensi diterapkan pada berbagai industri untuk mempertahankan kinerja heat exchanger agar selalu dalam kondisi optimal.
