Boundary layer is a reflection of the phenomena occurring in the combustion of liquid fuels with perpendicular to the surface of adding mass. For study the influence the thermal boundary layer on the process of combustion a special test stand has been developed, in which the flow of the medium with the addition of mass can be realized. Quartz windows and magnesium oxide powder, which is added for allow visualization of the airflow stream. Quartz windows are placed in the sidewalls of the chamber. The paper presents the test stand. The test stand consists of the following main components: test chamber, the main air preparation module, auxiliary air preparation module, module of particulate cartridge, air compressor, compensation tank, control unit and accessories in the form of filters, valves, pressure gauges and automatic control. Velocity of flow through the test chamber is controlled with air pressure from air preparation units and with the location of the regulatory fin at the end of the measuring chamber. The cartridge unit produces a homogeneous mixture of MgO particulates in air. Test results of the axial velocity profile at a distance of L=0.35 m obtained with LDA and PDPA laser equipment and ANSYS FLUENT numerical computations. Important for the combustion process is laminar boundary layer in laminar flow and laminar sublayer in turbulent flow.
