Investigation of transonic flow in the vapor channel of a high-temperature heat pipe in the case of arbitrary heat delivery to the heating zone
Abstract
Attention is given to the operation of a high-temperature heat pipe with emphasis on the transonic flow of metal vapors from the heat-carrying fluid (e.g., such liquid metals as lithium and sodium). The equations of conservation of mass, energy, and momentum, together with a suitable equation of state for the vapor, are reduced to a form suitable for numerical treatment. Comparison of pressure drops along the length of the heating zone, obtained by solving the differential equations and calculated for the case of incompressible vapor, shows satisfactory agreement only for low heat-flux values.
