Abstract: Analisis aliran udara terhadap mobil perlu dilakukan, untuk mengetahui dampak apa yang terjadi apabila aliran udara mengalir melalui bagian permukaan bodi mobil dan agar dapat menentukan sifat aerodinamis suatu mobil. Masalah difokuskan pada bentuk desain bodi mobil yang mempengaruhi nilai hambat aliran udara. Pada penelitian ini, analisis dilakukan dengan cara mensimulasikan aliran udara menggunakan perangkat lunak (CFD) Solidworks 2017 – flow simulation dan mobil dibuat dalam bentuk prototipe virtual. Pada proses simulasi aliran udara, variasi kecepatan aliran udara yang diberikan adalah 40 km/h (11,11 m/s), 60 km/h (16,67 m/s) dan 80 km/h (22,22 m/s) terhadap 3 (tiga) variasi model mobil yang berbeda. Dan dari analisis yang dilakukan, maka didapatkan hasil rata-rata koefisien drag (Cd) pada model desain 1 sebesar 0,446044 sedangkan model desain 2 sebesar 0,301518 dan model desain 3 sebesar 0,587565. Sedangkan untuk hasil rata-rata drag force nya untuk model desain 1 sebesar 319,0187 N untuk model desain 2 sebesar 190,4592 N dan untuk model desain 3 sebesar 293,3453 N. Dari hasil tersebut didapatkan bahwa model desain 2 adalah yang paling rendah nilai hambatnya terhadap aliran udara, sehingga model 2 dikatakan model mobil yang paling aerodinamis dari model 1 dan model 3. Air flow analysis of a car needs to be carried out, to find out what impacts occur when air flow flows through the surface of the car body and to be able to determine the aerodynamic properties of a car. The problem focuses on the shape of the car body design which influences the air flow resistance value. In this research, the analysis was carried out by simulating air flow using Solidworks 2017 (CFD) software - flow simulation and the car was created in the form of a virtual prototype. In the air flow simulation process, the variations in air flow speed given are 40 km/h (11.11 m/s), 60 km/h (16.67 m/s) and 80 km/h (22.22 m/s). ) for 3 (three) different car model variations. And from the analysis carried out, the average drag coefficient (Cd) in design model 1 was 0.446044, while design model 2 was 0.301518 and design model 3 was 0.587565. Meanwhile, the average drag force results for design model 1 were 319.0187 N, for design model 2 it was 190.4592 N and for design model 3 it was 293.3453 N. From these results it was found that design model 2 has the lowest resistance value to air flow, so model 2 is said to be the most aerodynamic car model compared to model 1 and model 3.
