Hydraulic Engineering into the 21st Century: a Rediscovery of the Wheel ? (1) A Review
نویسنده
چکیده
Hydraulics is the branch of civil engineering related to the science of water in motion, and the interactions between the fluid and the surrounding environment. It is shown that hydraulic engineers were at the forefront of science for centuries. The end of the 20th century marked a change of perception in our society for hydraulic engineering. Is there a need for further hydraulic engineering ? Yes, definitely. This is illustrated with an example (culvert design) and complemented by a second paper (CHANSON 2003). Some reflexions on the role of water engineering are presented. It is suggested that hydraulic engineers and academics must be pro-active to develop further scholarship and quality expertise as a part of a long-term strategy.

Hydraulic Engineering into the 21st Century: a Rediscovery of the Wheel ? (2) New Challenges
Hydraulics has been at the forefront of science for centuries. In this paper, new exciting developments are presented in terms of energy dissipation and multiphase flows. These include the hydraulic design of rectangular dropshafts and stepped chutes for embankment dams, and new air-water studies of spillway flows and dam break waves. The findings demonstrate innovative hydraulic research which...
متن کاملHydraulic anti-lock, anti-skid braking system using fuzzy controller
To maintain the stability trajectory of vehicles under critical driving conditions, anti lock-anti skid controllers, consisting of four anti-lock sub-controllers for each wheel and two anti-skid sub-controllers for left and right pair wheels have been separately designed. Wheel and body systems have been simulated with seven degrees of freedom to evaluate the proper functioning of controllers. ...

متن کاملThe Effect of Geometrical Characteristics of Desiccant Wheel on its Performance
Desiccant wheels are widely used in buildings to control humidity and reduce energy consumption. A model is presented based on transient coupled heat and mass transfer, to model, design and analyze the effects of geometrical characteristics of a honeycombed rotary desiccant wheel and its performance. Governing equations are solved numerically using finite volume method and the model is validate...
متن کاملTo Have an Ethos Transplant, as It Were: Iranian Organizations in Washington DC in Early 21st Century
Based on eighteen months of ethnographic fieldwork from 2004 to 2006 among a range of Iranian organizations in Washington, D.C., this article argues that the studied organizations were engaged, without being always necessarily aware of it or formulating it as such, in what we may call an “ethos transplant:” a transformation of “Iranian character” and political culture to make it more susceptibl...
