Abstract

tahunan yang merupakan bagian dari Formula Student of Automotive Engineering (FSAE) yang diadakan di Australia dengan peserta yang diikuti oleh mahasiswa di seluruh dunia. Nogogeni ITS Team untuk pertama kalinya megikuti kompetisi ini pada tahun 2020. Pada kategori design event, Nogogeni berfokus pada realiability and maneuverability kendaraan. Pengembangan aerodinamika pada mobil sangat penting untuk mendapatkan performa yang maksimal dan meningkatkan keselamatan pada mobil. Penambahan front wing dan rear wing pada mobil sebagai solusi untuk meningkatkan performa aerodinamika mobil tanpa harus menambah massa.
Parameter yang dibahas dalam proyek akhir ini yaitu kecepatan dan tekanan pada mobil. Jenis airfoil Eppler E423 digunakan untuk front wing dan rear wing. Dilakukan pemodelan numerik dengan menggunakan software fluent secara tiga dimensi. Simulasi Computational Fluid dynamics (CFD) dilakukan dengan domain komputasi lintasan lurus dan kecepatan udara 22.22 m/s. Model turbulensi yang dipakai yaitu K-epsilon Realizable dengan aliran steady. Karakterisktik aliran dinyatakan dalam bentuk kontur distribusi tekanan, vektor kecepatan, dan grafik distribusi Cp.
Hasil menunjukkan Nilai CD dan CL mobil tanpa menggunakan front wing dan rear wing adalah 0.36 dan -0.136. Dengan penambahan front wing saja CD dan CL meningkat menjadi 0.35 dan -0.829. Selanjutnya dengan penambahan rear wing saja CD dan CL meningkat menjadi 0.38 dan -0.684. Kemudian penambahan front wing dan rear wing pada mobil dihasilkan nilai CD dan CL sebesar 0.46 dan -1.265.
=====================================================================================================
Formula SAE Australasia (FSAE-A) is an annual competition that is part of the Formula Student of Automotive Engineering (FSAE) held in Australia with participants from all over the world. Nogogeni ITS Team for the first time participated in this competition in 2020. In the design event category, Nogogeni focused on vehicle reliability and maneuverability. The development of aerodynamics in the car is very important to maximize its performance, and increases the safety of the car. The addition of front and rear wing on the car is a solution to improve its aerodynamic performance without increasing its mass.
The parameters discussed in this final project are velocity and pressure on the car. Nogogeni selected the type of Eppler E423 as the airfoil of the front and rear wing. Performed numerical modeling using fluent software in three dimensions. Then a Computational Fluid dynamics (CFD) simulation is performed with a straight-line computational domain and an air velocity of 22.22 m/s. The turbulence model used is K-epsilon Realizable with steady flow. Flow characteristics are expressed in the form of pressure contours, vectors velocity, and Cp distribution graphs.
The results showed that the CD and CL values of the car without using the front and rear wing are 0.36 and -0.136. With the addition of the front wing, CD and CL increased to 0.35 and -0.829. Furthermore, with the addition of the rear wing, CD and CL increased to 0.38 and -0.684. Then the addition of the front wing and rear wing on the car resulted in CD and CL values of 0.46 and -1.265.
