    Abstract: Millions of people are killed or seriously injured on the roads due to terrified accidents every year. Most of these accidents are attributed to the over-speeding of the road vehicles. Thus, the road speed limiter (RSL) is a very important technique to reduce the possibility of road accidents. An interesting idea to control the speed of the vehicle... Show More

    Abstract: It is well-known that buses comprise an important part of mass transportation and that there are many types of buses. At present, the bus transportation is cheaper and easier to use than other means of transportation. However, buses have some disadvantages such as air pollution due to engine exhaust. This study is an attempt to reduce the gas emiss... Show More

    Abstract: The purpose of this work is to study the aerodynamic performance of a tandem C4 base-profile compressor blade using numerical tools. In this paper, the flow along the tandem blade is studied for various relative blade positions. In all the studied cases, the front blade is fixed and the position of the rear blade is varied as a function of the axia... Show More
