The experimental investigation of turbulence in the nozzle behind grids and spheres as the instrumentation for turbulent combustion of premixed flows by means of PIV and thermoanemometry was carried out. These methods were compared and applied in turbulent flows behind grids and spheres. Flows with relatively low turbulence intensities of the mean flow velocity (~1%), corresponding to the laminar flow in the case of absence of obstacles at low flow rates were investigated. Numerical simulation of the flow in a channel with changing geometry was carried out. A good agreement between laboratory experiments and numerical simulations was obtained. The developed experimental device is recommended for use in turbulent combustion of premixed flows.
