Elektrohydrodynaamisia

Elektrohydrodynamisia, often abbreviated as EHD, is a branch of fluid dynamics that studies the effects of electric fields on the motion of fluids. The term was coined by Russian scientist Vasily Shukhov in 1924. EHD phenomena are observed when an electric field is applied to a fluid, causing the fluid to move. This movement can be due to the interaction between the electric field and the charges present in the fluid, or due to the electrokinetic effect, where the electric field causes the fluid to move by inducing a charge separation.

EHD has applications in various fields, including aerospace engineering, where it is used to control the flow of propellants in spacecraft engines. It is also used in the design of microelectromechanical systems (MEMS), where it can be used to pump fluids at the microscale. In the field of medicine, EHD is used in the development of drug delivery systems, where it can be used to transport drugs through the body.

The study of EHD involves the use of mathematical models and experimental techniques. Mathematical models are used to describe the behavior of fluids under the influence of electric fields, while experimental techniques are used to measure the properties of fluids and the effects of electric fields on their motion. EHD is a complex field that requires a deep understanding of both fluid dynamics and electromagnetism.
