Brevnov O. Improvement of hydrodynamic filters by the swirl of stream in circular area outside filtеrelement.

For the increase of efficiency of the hydrodynamic cleaning of liquid by the use of rollup of stream research of hydrodynamic descriptions of stream of bearing liquid is conducted in the working cavity of hydrodynamic filter with the rollup of stream. Found out conformities to law of motion of the self-weighted particles in the area of separation of admixtures of hydrodynamic filter with the rollup of stream. The rational construction of filter, using the rollup of stream in combination with reticulated filterelement and the method of calculation of his hydrodynamic parameters is developed is grounded. Experimental researches which confirmed efficiency of the offered device of cleaning and adequacy of the got theoretical results the real physical processes are conducted. Middle divergence between the calculation and got as a result of experiment values of the compared parameters was 8,3%.
