Abstract

Mobil Pancasona adalah salah satu jenis kendaraan yang dirancang untuk kendaraan yang hemat energi, ramah lingkungan, dan effisiensi yang tinggi . Salah satu usaha untuk mewujudkan rancangan ini, dipilih kendaraan bertenaga listrik dengan bentuk bodi ringan dan aerodinamis. Mengingat bentuk bodi mobil Pancasona yang ada sangat dimungkinkan untuk dimodifikasi, maka Perancangan modifikasi bodi merupakan suatu langkah strategis dalam mengurangi gaya hambat aerodinamika pada bodi kendaraan guna peningkatan efisiensi pemakaian baterai (penghematan energy). Salah satu usaha untuk meningkatkan peforma body kendaraan, yaitu dengan penambahan diffusor pada bodi. Tujuan tugas akhir ini untuk mengetahui karakteristik aliran fluida melintasi bodi mobil Pancasona dengan Modifikasi 2 diantaranya: contour tekanan, pressure coefficient (Cp), drag coefficient (Cp) dan lift coefficient (C,) dengan menggunakan analisa sudut pandang 2D melalui software fluent 6.3.26. Dari hasil analisa didapat bentuk modifikasi yang telah dilakukan di bagian leading edge, diffuser (rear end) bodi, berkontribusi terhadap penurunan tekanan didaerah leading edge dan penundaan separasi point di daerah rear end dan terjadi penurunan nilai wake sebesar 6,006%.

Pancasona car is one type of vehicle that is designed for vehicles that are energy efficient, environmentally friendly, and high efficiency. One attempt to realize this plan, selected electricpowered vehicle with aerodynamic shape and lightweight body. Given the form of the existing car body Pancasona very possible to be modified, then the modified body design is a strategic step in reducing the aerodynamic drag on the vehicle body in order to improve the efficiency of battery consumption (energy saving). One attempt to improve Performance vehicle body, namely with the addition diffuser on the body front and rear F' inal goal is to determine the characteristics of the fluid flow across the car body modification. The objective of this final project is to know the flow characteristics of fluid through the body of second modified Pancasona,namely: contour of pressure, pressure coefficient (Cp), drag coefficient (Cp) and lift coefficient (C,) on the body of second modified Pancasona using 2 Dimensional analysis with 6.3.26 fluent software. Obtained from the analysis of a modified Jorm that has been done at the leading edge, a rear end and a diffuser body, contributing to the decrease in pressure areas and delays leading edge separation point in the rear end and wake impaired with amount of 6,006%.
