Speech Title--Machine Learning Enabled Quality Improvement in Samrt Manufacturing Systems

Speech Abstract--In a smart manufacturing system, a large number of sensors are installed to monitor machine status, process variables, product quality, and the overall system performance. It is always a challenging problem of how to analyze those massive amount of data effectively for cost reduction and quality improvements in all manufacturing companies. This presentation will discuss research opportunities, challenges, and advancements in this important research area, especially how machine learning concepts and algorithms can be used to solve challenging quality improvement problems. Examples of ongoing research projects will be used to articulate the frontiers of this research area. All examples come from real data and problem in industrial production systems. This presentation will emphasize the motivations of these research undertakings: challenges to be overcome, new methods that were developed, validation/implementation undertook, as well as the potential impacts.

Speech Title--Feature-based cyber-physics modeling in complex energy production systems

Speech Abstract--Cyber-Physics System (CPS) has been recognized as the core concept in modern industrial trends, especially related to manufacturing sector. It has been the new discovery by the author that the similar CPS concept, feature-based CPS, can be applied to complex energy production systems such as SAGD process in oilsands development in Canada. For example, bitumen production involves efficient performance of the underground tooling which again depends on the semantics knowledge about and the effective control of the physical world phenomenon – SAGD process. Virtual simulation could be helpful to understand and control the phenomenon. This presentation try to address the feature-based CPS approach with some in depth research results and multi-disciplinary collaboration. For example, computational fluid dynamics (CFD) is a powerful tool to analyze the flow field and then improve design. However, the use of CFD still requires strong expertise and extensive training, which places a barrier for its broader application. Feature-based CAD/CAE integration improves the usability via two new types of engineering features, fluid physics feature and dynamic physics feature. They convey the simulation intent and enable dynamic CFD solver setup automation and robust simulation model generation. Further, the association between simulation intent and design intent which is conveyed by another newly defined fluid functional feature is suggested to achieve seamless integration, which keeps the consistency in the complex product development process. Consequently, an optimal design could be possibly achieved by optimization coupling with production operation, manufacturability and cost analysis. A case study of steam assisted gravity drainage (SAGD) outflow control device (OCD) is presented at last to show the prospective benefit of the method.

Speech Title--Study of Oscillating Flow in an Engine Regenerator

Speech Abstract--Regenerator is the key component in a high efficiency Stirling engine. Currently, most regenerators are made of either the random fibers or woven screens. However, these regenerators have high flow losses, leading to low engine performance. To alleviate this problem, a foil regenerator was implemented. In this research, a oscillating flow test rig was designed and manufactured. The test rig was designed to generate the sinusoidal flow motion as in typical Stirling engines. Foil regenerators were tested under oscillating flow conditions. Dynamic pressure transducers were implemented to determine the pressure drops. Testing was conducted over a few hundred cycles and the measured pressures were ensemble-averaged to generate cyclic variation of pressures at the inlet and outlet of the regenerator. The friction coefficient was calculated based on Darcy-Weisbach equation. The validity and the accuracy of the measurement were verified by CFD analysis and other codes.
