- Аннотация: In this paper, new regimes of flow and heat transfer in the 100 kW IPG-4 plasmatron were investigated. The flow was generated by installing a slit nozzle behind the 80 mm diameter discharge channel. Using slug calorimeters, the heat fluxdistribution along the axis of symmetry of a 100x100x10 mm copper plate flown around by an air plasma jet at the angles of attackof 0° and 30° was obtained. A water-cooled 100x100x10 mm copper plate with a grid of injection holes was made. The plate’sholes were used to inject acetylene or propane in the boundary layer, enabling visualization of streamlines on the plate surface.The surface temperature of a flat specimen made from "Buran" orbital vehicle heat shield tile with white low-catalytic coating wasmeasured for the longitudinal flow around the surface using the spectral pyrometry method
