Advances in avionics and weaponry are leading to higher thermal loads for next generation military aircraft beyond what traditional PAO coolant loops can handle. One proposed solution is to use a phase change fluid to capture the additional heat.
Due to fluctuating orientation and heat load transient modeling is critical. As a first step, the focus of this work is to demonstrate the effects of diameter (3/8” through 2” pipe) and orientation on flow patterns observed visually and identified through capacitance methods.
