The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...
Diesel exhaust fluid ( DEF; also known as AUS 32 and marketed as AdBlue[ 3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water. DEF is consumed in a selective catalytic reduction (SCR) that lowers the concentration of ...
The interactions of the air and water flow allow a partial equalization of temperature, and evaporation of water. The air, now saturated with water vapor, is discharged from the top of the cooling tower. A "collection basin" or "cold water basin" is used to collect and contain the cooled water after its interaction with the air flow.
In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.
The streamlines show the direction of the fluid flow, and the color gradient shows the pressure at each point, from blue to green, yellow, and red indicating increasing pressure. In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids — liquids and gases.
Fluidized bed combustion ( FBC) is a combustion technology used to burn solid fuels . In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials ( sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
Outline of fluid dynamics. The following outline is provided as an overview of and topical guide to fluid dynamics: In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids — liquids and gases.
Brake fluid. Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, light trucks, and some bicycles. It is used to transfer force into pressure, and to amplify braking force. It works because liquids are not appreciably compressible .
