Experimental research of influence of various aerodynamic devices on flow pattern of a lorry

Abstract

In activity influence of various aerodynamic devices on flow pattern of a production lorry of the corporation KAMA3 (Russia) experimentally is researched. The experiments were conducted in an aerodynamic pipe T-503 NSTU on a scale model 1:lO. The flow patterns, field of velocities and their oscillations in a neighbourhood of model are obtained at presence and absence of various superimposed aerodynamic units. Is shown, that at symmetrical flow around the installation of fairings on a roof of a cabin and lateral doors essentially reduces of width of boundary layers, intensity of a vorticity in them, and general force of resistance of air.
