ABOUT ONE CLASS OF EXACT DECISIONS NAVIER-STOKES EQUATIONS T.A.Obgadze 0175, street Kostava 77, Georgian technical university, faculty of computer science and control systems, Tbilisi, Georgia tamaz@mail.ru In work on the basis of bidimentional statement of a problem about current of a viscous incompressible liquid, equations Navier-Stokes, which write down in a dimensionless kind naturally are under construction. Numerical factors of similarity turn out: number Strouhal's , Euler's number, number Froude's and Reynolds's number. Considering bidimentional statement of a problem, the algorithm of a finding of the whole class of exact decisions of equations Navier-Stokes is under construction. In that specific case, exact decisions fading cells currents Benar's with Rectangular cells are under construction. U = ( a sin y + b cos y ) e 1 Fr
