摘要：

Problem statement. Modern informational technologies make it possible to solve various complex problems of aerodynamics including problems of ventilation at different dynamic characteristics of flows. The article deals with the problem of ventilation with the use of low-velocity irrotational air flows. Known numerical methods of calculation of electric current related to the solution of large systems of partial differential equations and are faulty with respect to reliability and calculation precision. The use of the method of conformal mappings to determine velocity fields in ventilation problems is substantiated. Results and conclusions. The method for calculation of velocity fields and electric current lines in ventilated premises has been developed based on the method of conformal mappings and assumption of irrotational type of air flow motion. Application of this method allows one to calculate required fields using simpler algorithms without multiple computer calculations.
