Abstract

The objective of this study is developing methodology of external aerodynamic analysis and simulation analysis of a passenger BUS ISUZU SAZ HC 40 for prediction of drag coefficient and its impact on fuel consumption with experimental validation. It has been checked that to resolve the air drag, the automobile absorbs possible the necessary engine power. Baseline model of passenger BUS ISUZU SAZ HC 40 was evaluated for estimating fuel consumption using Computational Fluid dynamics (CFD) methodology. The effects of the CFD were confirmed with the variability of experimental data. ISUZU architecture has been designed to reduce fuel usage with criteria such as window tilt, rounding and tapering corners and rear draft angle. Optimized ISUZU design is also ensured to meet functional specifications as Uzbek standartation. At Turin Polytechnic University in Tashkent, the prototype of the integrated ISUZU system was experimentally evaluated. The CFD and experimental test findings were reviewed and considered to be in good agreement. With the streamlined configuration of the ISUZU, it is observed that while the weight of the ISUZU was raised, the fuel efficiency remained almost the same.
