Abstract

Cooling tower merupakan sistem pendingin pada industri yang dibutuhkan dan berfungsi mengurangi suhu air yang telah mengalirkan air panas dari sistem lainnya. Effectiveness sistem ini dipengaruhi oleh penurunan temperature, dan packing sebagai media pertukaran panas dan massa antara air dan udara. Penelitian ini bertujuan untuk menganalisis pengaruh susunan packing dan variasi laju aliran massa udara terhadap kinerja pendinginan pada cooling tower tipe induced draft. Metodologi yang digunakan adalah simulasi numerik ANSYS Fluent untuk menganalisis performa sistem. Simulasi model 3D menggunakan metode Computational Fluid Dynamics (CFD) dengan memodelkan partikel menggunakan model Discrete Phase Model (DPM). Simulasi melibatkan variasi jarak antar layer packing dan laju aliran massa udara pada dua jenis susunan: Horizontal Corrugated Packing (HCP) dan Vertical Corrugated Packing (VCP). Parameter yang dianalisis meliputi penurunan temperatur, koefisien perpindahan panas konveksi, dan nilai effectiveness. Dari hasil analisis, diperoleh bahwa susunan VCP dengan jarak 70 mm dan laju aliran massa udara 0.3 kg/s memberikan effectiveness tertinggi yaitu 51%, yang dipengaruhi oleh nilai range dan approach. Kesimpulan menunjukkan bahwa susunan dan jarak packing signifikan mempengaruhi effectiveness cooling tower, Nusselt Number (Nu) yang mempengaruhi nilai koefisien konveksi, Reynold Number (Re) yang dipengaruhi oleh nilai kecepatan udara dan air

A cooling tower is an essential industrial cooling system that functions to reduce the temperature of water that has carried heat from other processes. The system's effectiveness is influenced by the temperature drop and the packing, which serves as a medium for heat and mass exchange between water and air. This study aims to analyze the effect of packing arrangement and variations in air mass flow rate on the cooling performance of an induced draft cooling tower. The methodology used is numerical simulation in ANSYS Fluent to evaluate the system’s performance. A 3D model simulation was conducted using Computational Fluid Dynamics (CFD), with particle modeling using the Discrete Phase Model (DPM). The simulation involved variations in the spacing between packing layers and air mass flow rates, applied to two types of configurations: Horizontal Corrugated Packing (HCP) and Vertical Corrugated Packing (VCP). The parameters analyzed include temperature drop, convective heat transfer coefficient, and effectiveness. The analysis results show that the VCP arrangement with 70 mm spacing and an air mass flow rate of 0.3 kg/s provides the highest effectiveness at 51%, which is influenced by the range and approach values. The conclusion indicates that packing arrangement and spacing significantly affect the cooling tower’s effectiveness, the Nusselt Number (Nu) which influences the convective heat transfer coefficient, and the Reynolds Number (Re) which is affected by air and water velocity
