Stabilized Loop Heat Pipe Architecture for Reliable Operation Under High-Power Transients

What is it about?

This paper analyzes test data obtained by the authors and corresponding results of numerical simulation of transients in a high power loop heat pipe (LHP) with a small diameter condenser bypass. Thermal-fluid oscillations (TFOs) and evaporator partial dryouts were observed for the same high-power LHP. Adding a small diameter tubing condenser bypass to the LHP entirely eliminated all oscillations and partial dryouts, making its operation smooth for all power levels and most demanding transients.
