The science of electrohydrodynamics, commonly referred to as electro-fluid-dynamics or electrokinetics, examines the motion of electrically charged fluids. It is the investigation of the movements of ionised atoms or molecules as well as their interactions with electric fields and the fluid in the vicinity.
Electrohydrodynamic procedures like electrospraying and electrospinning are easy, adaptable, and economical. For the creation of micro- or nanoparticles and micro- or nanofibers, both techniques employ an electrically charged jet of polymer solution.Electric motors are tools for transforming electrical energy into mechanical energy.
The electric motor, in scientific terms, is a device that transforms electrical energy into motive energy or electrical energy into mechanical energy. Fig.
The Global Electrohydrodynamic Motor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Electrohydrodynamics is used to create an EHD motor for a water solution. Dielectric fluids are frequently used in industries as insulating oils because of their extremely low conductivity values (10-8 Sm-1).
Electric body forces are produced when a dielectric fluid is exposed to a strong electric field (>l kVmm-1), because the dielectric constant and electric conductivity are not uniformly distributed throughout the fluid.Convection, turbulence, and chaos are only a few examples of the macroscopic motions that can be created in the systems under certain circumstances.
Electrohydrodynamic (EHD) effects are the names for the fluid’s secondary motions that are caused by strong electric fields. Electric energy is efficiently transformed into fluid kinetic energy in the EHD jet flow. With regard to novel fluid devices, the EHD jet is therefore a particularly appealing application.
They use conductive fluids such as pure distilled water and aqueous solutions of ethanol and glycerin as working fluids to concentrate their attention on the prototype of an EHD motor in this work. They were able to create a high-speed jet for aqueous solutions and design the water motors.
Due to the secondary flow of water being created in the direction from the negative to positive electrodes, the polarity controls the rotating direction. At 7.0 kV, the rotation speed is in the range of 4.09 rps. Discussion of motor performance in relation to the working fluids’ viscosity and electric conductivity.
