Book excerpt: Abstract : Global warming has led to increased research in renewable energy and the need for efficient energy storage systems. Lithium-ion batteries are a promising solution, but their performance degrades at high temperatures. To improve thermal management, researchers are exploring the use of phase change materials (PCMs) combined with fin structures. Different fin geometries impact heat dissipation. The goal of this study is to perform a reliability-based design optimization of a battery thermal management system for a desired reliability and temperature level. The design geometry consists of four components that include the lithium-ion cell at the core having a fin structure with a PCM module attached to it, and an acrylic shell on the outside. The geometric design variables include the dimension of the outer radius of the battery shell (overall diameter of the battery) and three dimensions of a T-shaped fin structure. Along with the four design variables, two uncertainty parameters of battery heat generation that happens at the core and the ambient convective heat transfer coefficient on the outer surface are considered for the reliability based design optimization. Latin Hypercube Sampling is used to generate sample points for thermal analysis that is done using ANSYS Mechanical APDL. These data points are used to train a machine learning model to predict temperatures for unknown design samples during the optimization process. The optimization is done using a type of an evolutionary algorithm. Initially the optimization problem was formulated using a single objective function that was minimized to find the optimal design configuration. The results of this optimization encouraged to pursue the ix possibility of multiple optimal solutions and formulate a multi-objective optimization problem.

This book was released on 2019 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade, design under uncertainty has received significant attention and a wide range of applications from designing simple product components to designing complex and emerging engineered systems. Uncertainty is ubiquitous in engineering design. Therefore, it is crucial to discover an optimized design that satisfies the reliability requirements. A commonly used design optimization methodology for engineering systems comprises deterministic modeling and simulation-based design optimization. However, traditional deterministic design optimization (DDO) is not capable of considering design uncertainty. Taking uncertainties into account could be handled by using a technique called Reliability-based design optimization (RBDO). Reliability analysis, as the fundamental process in RBDO, evaluates the probability of failure as a probability of a function to reach a defined limit state. RBDO requires reliability analysis to estimate probabilistic design constraints iteratively, and it can be very time consuming because the reliability analysis requires huge numbers of input data. Hence, efficient reliability analysis is inevitable especially when computationally expensive simulation such as finite element runs is involved. The ultimate purpose for any reliability analysis problem is to increase the efficiency and accuracy of the calculations. There are still clear deficiencies in terms of efficiency and accuracy of the solution methods which is used depending on the nature of the problem (level of nonlinearity and size). The aim of this research is to propose efficient methods for reliability analysis in the design of energy harvesters and sensor network systems. We apply these techniques to high dimensional RBDO that possibly involves finite element analyses. Dimension reduction (DR) method is implemented in the first part of this dissertation to address design under uncertainty for complex engineering problems. Next, an adaptive improved response surface method (AIRSM) in conjunction with a new regression based model is proposed for solving reliability problems and compared with DR method in terms of efficiency and accuracy. Finally, a high dimensional complex reliability problem is solved using Kriging model and Genetic Algorithm (GA). This research aims to suggest practical and efficient reliability analysis methods to minimize the computational cost while maintaining accuracy to be integrated into the RBDO.
