Startup Performance

Supercritical startup of cryogenic loop heat pipes (CLHPs) has been investigated both analytically and experimentally. Mathematical model of the supercritical startup has been established using the nodal network method, and parametric study is conducted where the effects of working fluid charged pressure, parasitic heat load from the ambient, etc., on the supercritical startup characteristics are incorporated and evaluated. The result improves understanding of the effects of these parameters on supercritical startup and identification of those conditions under which supercritical startup can and will occur. In addition, the modeling effort has led to an enhanced understanding of supercritical startup performance.
