The time-dependent flow through throttle valves: a computational and experimental investigation

By Raimond W. Alsemgeest


The automotive industry is, perhaps, and that is left open to debate, one of the most important engineering fields, and one which is increasingly influential on our everyday lives. Automotive engineering brings together all aspects of engineering knowledge to produce the one product that so many people have become dependent upon. The industry itself is vast and many tangents can be drawn from it, hence here we must define the area of interest to which this work relates. The initial concept for the work carried out stems from the passenger car industry; however, the work has more farreaching benefits and implications. As passenger vehicles become increasingly popular and increasingly advanced, so the need increases to understand more of the operation of all aspects of the vehicle.\ud This work stems from a need to gain understanding of the flow of breather and blowby gases within an internal combustion engine (ICE) with the long-term aim of fully understanding the processes involved to enable improved engine design and reduced pollutant production. The latter is a significant driving force as legislation becomes more strict on the level of pollutants emitted from vehicles and engines. This work therefore not only reflects on passenger vehicles, but any other industry or product that uses ICEs
