Fluids, which include both liquids and gases, are very important resources. They provide raw materials for direct exploitation, but equally importantly fluids also provide us with mechanism for certain other processes, and at times even act as sources of energy. Man has been controlling the flow of fluids for a long time. Ancient Rome had intricately engineered sewage and water system which dynamically provided energy and was self sustaining. Archimedesí water wheel was a much celebrated mechanism already. Dams and pipelines have been made around the world which have manipulated the dynamics of fluids.
Fluid and gas control remains a vast and important application area. The discovery of steam power meant that it had to be channeled to different systems, which required intricate structural evolution. Oil wells and pipelines have been used in ancient China since the 4th century; however the invention of fractional distillation of oil and its use in the internal combustion engine meant a revolutionary extension of the field of fluid control. Today, fluid control engineering rubs shoulders with mechanical engineering, thermodynamics, hydraulics, etc, and many major applications require some amount of fluid control with their systems.
This section of the webdirectory purports to provide a guide to resources in this field, from servicing agencies for various diesel engines to gasket manufacturers, from providers of pumps, valves, seals and fittings to boiler manufacturers.
