| description | The article considers the solution of the urgent problem of creating a micro-sized turbojet engine
using 3D printing. The article describes one of the ways to cool the walls of the heat pipe of a small
combustion chamber made of heat-resistant material 08KhN53BMTYu. One of the acceptable ways to
cool the walls of a small-sized chamber heat pipe is convective heat exchange of the outer side of the
heat pipe due to intense vortex formation in the boundary layer of the flow. This effect is achieved by
the device of projections on the outer wall of the heat pipe. The article highlights the peculiarity of the
shape of the protrusions, which must be carried out taking into account the technological limitations of
3D printing. The article presents a description of an experimental stand for the study of the thermal state
of the heat pipe of micro turbojet engines, the method of processing experimental data and the results
of experiments on the heat transfer of the heat pipe shell with and without them. |
