DURIP Noninvasive Spatiotemporal Measurement of Flow Characteristics in Self-Aware Thermal Management Components to Diagnose Emerging Fault Behaviors
Abstract
Many thermal management systems employed in DoD applications including U.S. Navy ships and platforms are characterized by time-varying thermal load conditions and require high reliability to ensure mission critical operations. Such conditions can yield to non-uniform heat loads, high heat fluxes, and flow instabilities, ultimately causing degradation phenomena and failures. In addition, thereis an ever-increasing demand for high heat flux removal from electronic and warfare devices, which necessitates advanced two-phase cooling systems and predictive control of two-phase flows. Designing thermal management solutions that can be self-aware of the thermal load conditions and health status will enable groundbreaking technological solutions. To address these research challenges, our team is proposing to design a new state-of-the-art testing facility equipped with noninvasive two-phase flow instrumentation to investigate the behavior of real thermal management components (e.g., topology optimized two-phase heat sinks, embedded jet impingement,oscillating heat pipes, ultra-compact bicontinuous unit cell heat sinks, etc.) under both nominal operating conditions and faulty scenarios with different intensities. Such a facility will allow for exploration into the feasibility of embedding sensing into thermal management materials to enable situational awareness and memory-based two-phase flow control mechanisms. The combination of two X-ray sources, scintillator plates, high-resolution high-speed cameras, and a high-precision infrared (IR) camera will provide uniquespatiotemporal measurements to investigate the highly dynamic two-phase flow conditions in a non-intrusive way. This proposal leverages interdisciplinary expertise within the Center for High Performance Buildings (CHPB) at the Ray W. Herrick Laboratories and the Cooling Technologies Research Center (CTRC) at Purdue. The proposed experimental facility will provide a framework for conducting transformative research on fundamentals of two-phase flow in thermal management devices, advancing measurement techniques to capture in-situ transient transport phenomena, investigate passive and active two-phase flow control with embedded-sensing in metamaterials, emulate faulty scenarios and correlate the performance degradation with high-fidelity flow visualizations. The facility will enhanceour capabilities to provide high-quality education at both undergraduate and graduate levels on the broad topics of thermal management systems and fundamentals of thermodynamics and heat and mass transfer. Moreover, it will provide a unique opportunity to supporteducational and research programs within the Purdue Military Research Institute across all the military departments of DoD.PubliclyReleasable
