Experimental investigation of conducting fluid flow in convergent channel
generated by alternating magnetic field.
The proposed project is devoted to experimental study of the field of velocities
of the conducting liquids. The conducting liquid (the fluid metal) is kept in
container, which presents itself the flat channel, the thickness of which linear
changes in one direction. The container is placed between negative and positive
poles of the electromagnet; moreover poles overlay only part of the container.
The channel is across penetrated by variable magnetic field; herewith the rotary
electric current is generated. The interaction of this current and external magnetic
field brings by generations the dissimilar electromagnetic forces. The forces vector
lie in the plane of layer. Under the action of forces appears the rotary current of
the fluid metal, which can be a transitional. This reveals itself in moving the
rotations in planes layer. The purpose of the work is an experimental study of the
field of velocities of rotary currents for different tilt angles of the channel.
The study will be conducted by conduction anemometer and ultrasonic Doppler anemometer.
The Results of the experiments also will be used for checking the results of mathematical
modeling of the given process. Given problem presents academic and practical interest.
It is used in steal industry.
In this process flat layer of the fluid metal is gradually crystallizing from wall to kernel.
And along it the fluid kernel presents itself narrowing layer. The mixing of the layer by such
currents can greatly raise the quality of the metal. Thereby, experimental modeling and studying
of given process will allow us to accumulating the experience for development of the similar methods.

Imbalance process in continuous medium."
In this experiment we measured the speed with the help of Doppler measurement system and with the
electromagnetic spead sensor, developed in our research centre.
The output speed sensor signal is measured by Agilent34401A multimeter, connected via USB interface
to our PC and data is accepted by Agilent34401A.vi (labview program for DAQ, developed by me).
