Startup of the Liquid-Metal Heat Pipe in Aerodynamic Heating Environments.
Abstract
As part of a US Army missile development program, liquid-metal heat pipes have been investigated to remove the high heat flux associated with the missile fins being located in hot exhaust gas paths. Using steady-state and transient analyses, a solution method has been developed to identify the required length of the condenser for a design operation when the heat pipe is coupled with aerodynamic heating and cooling environments. A simple transient analysis using the lumped heat-capacity method predicts the response of operating temperatures and the propagation of the continuum' front when the liquid-metal heat pipe is started from the frozen state.
