ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a method and a device for directing a fluid in motion.
As opposed to electromagnetic wave radiation, such as laser radiation, there are no effective ways to direct, or channel fluids or wave propagation in fluids without using any mechanical means such as tubing accompanying and enclosing the propagating fluid.
The object of the present invention is therefore to provide a method and a device, which makes it at least partially possible to enclose or direct fluids in motion such as sound wave motion without any mechanical means of guidance.
This is obtained by the features given in the appended claims.
SUMMARY OF THE INVENTION
The invention is the result of the discovery by the inventor that particularly collimated and coherent electromagnetic radiation appears to have the ability to shield or direct, such as guide, deflect or reflect a fluid such as air in motion. Tests conducted by the inventor using low energy laser radiation and audible sound emitted in the direction of laser radiation resulted in an appreciable higher level of sound measured at certain distances and orientations from the laser radiation than at other distances and orientations from the laser radiation, indicating fluid shielding or directional properties of laser radiation. While the physical and chemical mechanisms governing this supposed ability of electromagnetic radiation are not yet fully understood, it is assumed that electromagnetic radiation along its path, depending on its intensity or energy, forms a boundarylayer in the fluid. In the boundary layer the electromagnetic radiation is assumed to excite and ionize the adjacent molecules of the fluid, possibly into a plasma state, and in the case of a gaseous fluid, possibly into a vacuum state. The qualities of the fluid in the boundary layer excited by the electromagnetic radiation, differing from the qualities of the fluid outside the boundary layer, are believed to have the ability to direct and at least partially guide, or shield the fluid in motion approaching the boundary layer. Whether these differing qualities of the fluid in the boundary layer actually deflect, reflect, refract or impose a combination of one or more of these and possibly other effects to the molecules of the approaching motive fluid, is not yet fully understood.
According to one aspect of the invention, there is provided a method for directing a fluid in, wherein at least one curtain of electromagnetic radiation is provided for exciting the fluid at the curtain to form a fluid directional layer in the fluid
According to another aspect of the invention, there is provided a device for directing a fluid in motion comprising an electromagnetic radiation emitter adapted to create at least one curtain of electromagnetic radiation for exciting the fluid at said curtain to form a fluid directional layer in the fluid.
Other aspects and features of the invention are given in the claims and in the description of preferred embodiments.
