Aerodynamic Drag Reduction in Modern Consumer Automobiles

Within the course of their experiments, they uncovered many different types of aerodynamic drag on vehicles. In addressing these disparities, they came up with various modern designs to also help to reduce drag. Moreover, it can be seen that dissimilarities existed in the differences between racing car design and road car design, which had led them to explore the reasons why road vehicles did not look like racing cars. This paper will investigate other factors, such as European legislation, that influences the appearance of road vehicles. In addition, it will discuss how and why the appearance of modern cars changed in recent years through the use of texts, pictures, graphs, equations and diagrams. Moreover, the role of Bernoulli relationship on the flow around an object will be explored as well as an explanation of boundary layer properties. Finally, it will analyze flow control using passive methods like vortex generators. Clearly, researchers in their investigations had devised innovative ways to reduce the aerodynamic drag of modern road vehicles.
Bettes (1982) defined aerodynamic drag as occurring when a car moved through air and the energy that opposed its direction and slowed down its movement. Another more comprehensive definition of aerodynamic drag was: ”The resistance of the air to forward movement, sometimes called "aerodynamic drag". This is a factor of the shape of the vehicle, the objects which stick out (i.e., mirrors, mufflers, bumpers), the amount of turbulence at the rear of the vehicle, the nature of the vehicle's skin surface, and the amount of air going through the vehicle for cooling and ventilation. The faster you go, the greater the air friction (proportional to velocity²). At the same time, the power to overcome such friction is proportional to velocity³.” ( ...

Modern soil stabilization methods in condition of a dense urban environment
The present study is focused on the methods of soil stabilization, the modern day techniques and materials that are available, and the need and understanding of the methods such that soil stabilization in the urban dense areas can be successfully achieved improving the conditions of the soil, increasing their strength and making them more capable of bearing loads. Introduction: Stabilization of soil refers to the process of soil treatment through the use of chemicals or mechanically. This is primarily done to improve the engineering properties of the soil. The chemical materials that are in...

Social policy development for the aged in the modern day context
Over the past couple of decades, the senior citizens have become contributing members of the society in their own way (Chung, McLarney and Gillen, 2008). The complete change in the perception about the elderly in the past few decades warranted for a change in the way policy makers devised policies to meet their meets. In 2002, under the aegis of United Nations, the Second World Assembly was conducted in Madrid and the Madrid International Plan of Action on Aging was declared. The conference proposed a strong plan for providing social care and social development for the elderly, and for...

Tate Modern Case Study
The initial plan for the Tate modern was abandoned for a design that was meant to be modern and have the ability to meet the needs of clients. Therefore, combined effort of design team and client was devised as appropriate approach to the building. Mace played a role of negotiating the project management, which was critical in providing buildability and detailed construction advice. Tate modern project incorporated three underground oil tank and live switch station among many others (Grubiak, 2008). The expansion of the Tate modern project was deemed important because previously the building...

The Correlation Between Energy Reduction During The Operation Of A Building And The Carbon Footprint Of It.
In addition, the carbon footprint of a building is dependant on the dimensions of the proper coordination of the forms and space put in place over the time. This means that during the construction, the design should aim at energy reduction so that the amount of carbon footprint is reduced significantly. Modern housing design is a work aimed at satisfying customers need, setting measures of transforming the world by the architectural work and ensuring the quality of buildings (Bentley, 1999). In this regard, the design and transformation heavily rely on historical background and knowledge of...

.51 REFERENCES ….53 CHAPTER 2 2.1 WHAT IS FUEL ECONOMY? The fuel economy(FE) of any vehiclecan be calculated as a ratio of distance travelled per unit volume of fuel consumed or as the ratio of fuel consumption per distance travelled(GFEI,n.d.). An et al (2011,p4)note that fuel economy standards can be of various forms such as liters of fuel consumed per hundred kilometers of distance travelled or kilometers travelled per liter of vehicle fuel. The global average vehicle fuel consumption hoversaround 8L/100 km corresponding to 29.4 mpg and a global drive under the aegis of GFEI, whose...
