Instabilities in Two-Phase Thermal System
We have been delving into the fundamentals of flow instabilities in two-phase thermal systems and their impacts on the thermal systems as they influence to the system safety, reliability and lifespan. Flow instabilities are largely categorized into static and dynamic instabilities, and they include Ledinegg, parallel channel instability, density wave instability, and pressure drop oscillation, respectively. Identifying various types of instabilities in the thermal systems and unveiling its nature and impact on heat transfer mechanisms are our primary research interests. Instabilities are commonly observed in micro-channel heat sinks, nuclear reactor cooling loop, and natural circulation loop, and prediction and suppression of instability are considered as important design factors.
