Application of steam jet nozzle in heat pipes of mean temperature range

The work presents a part of a complex rated experimental research of heat-transfer intensification characteristics of the heat pipes of medium temperature range. At the butt (axial) direction of heat flow at the inlet into the heat pipe, being characteristic for the space application, appears a possibility of the jet steam nozzle usage which is analogous to the Laval nozzle and surrounded with a capillary porous insertion layer along the whole length, which increases the steam flow velocity and the heat pipe limit parameters.
