scientific novelty.

The designed technique of calculation has allowed to receive a number of new results to which it is possible to fall into the following:

1. The structure of a three-dimensional turbulent stream in the regular and again designed multiway case of system of heating of the car depending on an operating mode of a supercharger is in details examined:

·rasschitano a spatial field of speeds its non-uniformity also is determined at a heat sink flow;

·opredeleny spatial velocity profiles on an exit from deflektorov heating systems, are defined factors of non-uniformity of distribution of speed;

·polucheny estimations of losses of pressure on length of airlines;

·opredeleny pressure losses on a heat sink in a path of system of heating;

·rasschitano spatial distribution of a kinetic energy, and speed of a dissipation of a kinetic energy of turbulence in deflektorah a windscreen dusting.

2. Local and integral performances of stationary internal currents in paths of system of heating of the car depending on geometry and boundary conditions are received:

The arrangement and the local sizes otryvnyh zones is determined;

Integral values of distribution of speeds are defined,

Kinetic energy and speed of a dissipation of a kinetic energy

Turbulence on an exit from deflektorov heating systems.

Practical usefulness. The designed technique of calculation and projection allows to realise for a justification rational on aerodynamic resistance of a construction of system of heating of the car and affirming experimentally the received high-speed conditions of streams of air on an exit from system of ventilation of car Izh-2126 technical requirements of GOST R 50993-96.
