Analyzing Multiphase Flow in Membrane Electrode Assembly Using a Mixed Wettability Mathematical ModelDownload
Improving fuel cell performance at high current density is critical for reducing stack size, cost and weight in automobile applications. A major source of performance losses at high current density is the accumulation of liquid water in the electrode which blocks reactant transport. Studying...
This thesis investigates the experimental mechanical behavior of polymeric foams, specifically studying the effects of microstructural features (pore size and wall thickness), foam density, and strain-rate-dependency on their stress-strain, lateral-axial strain, and failure. This thesis explores...
Direct Imaging and Subsequent Modeling of the Cement Microstructure and Integrity of Cement/Casing and Cement/Formation InterfacesDownload
As a key component of the wellbore barrier system, cement provides zonal isolation and structural support during the entire life of a well. However, even when the cement is properly placed in the well, the zonal isolation may be lost over time. Failure to establish and maintain an effective...
Increasingly stricter performance requirements of pipelines are being driven by regulatory bodies, the energy industry, and public interest in protecting public safety, health, and the environment. A critical mechanical property influencing performance is toughness, and particular interest is...
