Research and Development of a New and Original Technology Based on Pulse Electrohydrodynamics for Construction and Water Sector Users

Studies of theoretical postulates of mathematical physics and electromagnetic theory have lead to useful research of the effects of electrical pulse discharges in water and possible applications in the construction industry and water sectors. Namely, theoretical research suggested to the authors of this new technology that such discharges could be used to create potentially useful strong electro-hydrodynamic shockwaves.

The objectives of the project were:

  • To investigate, develop and apply the new Pulse Electrohydrodynamic Technology (PELHYDT);
  • To design and fabricate PELHYDT experimental facilities for laboratory simulations of the regeneration of radial well laterals, the removal of sewer blockages, and soil consolidation and stabilization;
  • To conduct laboratory experiments and analyze collected data;
  • To conceptualize, design and develop three new solutions (in the form of patents) for application of PELHYDT in real-life situations;
  • To produce PELHYDT equipment and installations for industrial applications, create new jobs, eliminate a number of problems currently experienced by potential PELHYDT users in Serbia and other countries, and generate revenues for Jaroslav Cerni Instirute and the country.

The Project results are:

  • Three original experimental facilities for laboratory testing were investigated, designed, fabricated, installed and inter-connected:
  • The first experimental facility is intended to regeneration of radial well laterals under laboratory conditions, as shown in Figure 1.
  • The second experimental facility simulates removal of a sewer clogging, as shown in Figure 2.
  • The third experimental facility (Figures 3 and 4) is meant for soil consolidation under laboratory conditions.
