Does magnetofluid propulsion cause cavitation?

The adsorption concentration of the porous electrode increased with increasing loading voltage and porous electrode thickness and decreased with increasing inlet velocity. Magneto-fluid propulsion technology is a completely new type of marine platform propulsion, which requires almost no mechanical drive components and does not cause cavitation.

What is magneto-fluid propulsion technology?

Magneto-fluid propulsion technology is a completely new type of marine platform propulsion, which requires almost no mechanical drive components and does not cause cavitation. Therefore, it has great potential in noise reduction and acceleration.

What is a magnetohydrodynamic drive?

A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics. The fluid is directed to the rear and as a reaction, the vehicle accelerates forward.

How does seawater conductivity affect a magnetic fluid thruster?

The effect of the enhanced conductivity of seawater in the spiral channel on the magnetic fluid thruster is discussed below. At a certain voltage, the increase in seawater conductivity is accompanied by an enhancement in the current density through the seawater and a decrease in the pressure drop across the electrodes.

How do MHD forces affect internal propulsion?

As regards internal propulsion, the MHD forces are applied in a channel (Fig. 1a), inducing a pressure response of the flow. The pressure increases between the inlet and the outlet of the propeller leading to a propulsion by reaction of the ship. The magnetic field and electric current stay confined in the propeller.

How do conductivity enhancement systems affect a magneto-fluid thruster?

In the case of the conductivity enhancement system, the electromagnetic force and thrust of the magneto-fluid thruster tend to increase linearly.
