Abstract

Pada saat ini, perkembangan teknologi otomotif telah berkembang sangat pesat. Maka dari itu, perusahaan otomotif berlomba-lomba untuk memproduksi kendaraan yang mengutamakan keselamatan pengemudi, efisiensi mesin, dan aspek aerodinamis. Faktor aerodinamis berkontribusi banyak ketika kendaraan sedang melaju, untuk itu gaya drag harus seminimal mungkin. Urban Concept mobil Nogogeni 5 adalah salah satu kendaraan yang dirancang khusus untuk mobil hemat energi pada daerah perkotaan. Urban Concept mobil Nogogeni 5 dibuat untuk menggunakan tenaga listrik, dan mempunyai bentuk bodi yang ringan serta aerodinamis. Untuk mengetahui gaya aerodinamik pada kendaraan dilakukan karakteristik aliran di seluruh bodi mobil Nogogeni 5 menggunakan Ansys Workbench 18.1 dengan CFX-Solver. Tujuan tugas akhir ini adalah untuk membantu tim mobil listrik Nogogeni mengetahui karakteristik fluida yang mengalir di seluruh bodi mobil Nogogeni 5, yang meliputi kontur tekanan, koefisien tekanan (Cp), koefisien drag (Cd ) serta koefisien lift (Cl) secara 3 dimensi melalui software Ansys CFX-Post 18.1. Dari Hasil analisa aliran yang melintasi bodi mobil Nogogeni 5, koefisien drag (Cd) yang diperoleh selama simulasi senilai 0,127767461 sedangkan koefisien lift (Cl) senilai 0.0160181124. ============================================================================================= Nowadays, The development of automotive technology has grown very rapidly at this time. Therefore, the automotive company are competing to produce vehicles that prioritize driver safety, engine efficiency and aerodynamic aspect. Aerodynamic factors contribute a lot when the vehicle is in motion, to the drag force should be as minimal as possible. Nogogeni 5 Urban Concept car is one of the vehicles specifically designed to meet those needs. Nogogeni 5 are made available for use electricity and form a lightweight and aerodynamic body. To determine the aerodynamic forces on the vehicle performed flow characteristics around the Nogogeni 5 body car is using Ansys Workbench 18.1 with CFX-Solver. The purpose of this final project is to help the Team Nogogeni ITS determine the characteristics of and electric car flowing fluid at the entire body of the Nogogeni 5 car, which includes the contour of the pressure, the pressure coefficient (Cp), the coefficient of drag (Cd) and the coefficient of lift (Cl) in 3-Dimensionally through Ansys CFX-Post 18.1. From the analysis of the flow that crosses the body car Nogogeni 5, the coefficient of drag (Cd) obtained during the simulation is 0.127767461 and the coefficient of lift (Cl) is 0.0160181124.
