Abstract
Performa heat exchanger dapat ditingkatkan dengan memodifikasi bentuk tube dengan menambahkan body pengganggu (Inlet Disturbance Body). Perubahan bentuk geometri dapat meningkatkan perpindahan panas sisi eksternal. Berdasarkan hal tersebut, dilakukan penelitian dengan menambahkan splitter plate pada bagian upstream dengan variasi panjang L=D, L=1.5D, L=2D dan vortex generator pada bagian downstream. Tube yang digunakan adalah tipe staggered. Pada penelitian ini dilakukan dengan metode Computational Fluid Dynamics (CFD). Hasil dari simulasi pada pene;itian ini yaitu pada variasi L=D memiliki nilai koefisien drag terkecil yaitu 0.102046. Pada Pada variasi 1, separasi terjadi pada sudut 119 sebesar 0,003416 m/s. Pada variasi 2, separasi terjadi pada sudut 110 sebesar 0,024065 m/s. Pada variasi 3, separasi terjadi pada sudut 105 sebesar 0,00292 m/s. Nilai temperatur outlet tertinggi didapatkan pada variasi 1 yaitu 308.63434 K. Penurunan nilai bilangan Nusselt terjadi pada sudut 4⁰ (titik stagnasi) hingga sudut θ = 9⁰ yang merupakan titik dimulainya separasi.

The heat exchanger's performance can be improved by modifying the tube shape by adding the Inlet Disturbance Body. Changes in geometric shape can improve external side heat transfer. Based on this, research was carried out by adding a splitter plate on the upstream with variations in the length of L = D, L = 1.5D, L = 2D and vortex generators in the downstream. The tube used is the staggered type. In this study carried out using the Computational Fluid Dynamics (CFD) method. The results of the simulation on this study are that the variation of L = D has the smallest drag coefficient value of 0.102046. In variation 1, the separation occurs at the 119 of 0.003416 m/s. In variation 2, the separation occurs at the 110 of 0.024065 m/s. In variation 3, separation occurs at an angle of 105 of 0.00292 m/s. The highest outlet temperature value is found in variation 1 which is 308.63434 K. The decrease in the value of Nusselt number occurs at an angle of 4⁰ (point of stagnation) to the angle θ = 9⁰ which is the starting point of separation.
