Abstract

The two-phase flow structure in a flat polymeric pulsating heat pipe (PHP) is studied experimentally by high-speed imaging and digital image processing. While flow patterns in tubular pulsating heat pipes can be studied by inserting a short transparent section in a certain position along the channel, in flat PHPs built using transparent plastic sheets one can visualize the entire flow field in the adiabatic region between the evaporator and the condenser. High-speed movies were enhanced by digital image processing to highlight the liquid-vapor interfaces. Different flow patterns were identified, and sorted into a simple flow pattern map.
