Application of biomarker compounds as tracers for sources and fates of natural and anthropogenic organic matter in the environment

Creator:

Oros, Daniel R.

Abstract:

Determination of the source and fate of natural (higher plant lipids, marine lipids, etc.) and anthropogenically (e.g., petroleum, coal emissions) derived hydrocarbons and oxygenated compounds in the environment was accomplished using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) to characterize or identify molecular biomarkers to be utilized as tracers....

A study of micro-scale, fractal-like branching flow networks for reduced pumping power and improved temperature uniformity

Creator:

Alharbi, Ali Y.

Abstract:

A first generation, one-dimensional predictive model is proposed for designing heat sinks with fractal flow networks. A three-dimensional computational fluid dynamics (CFD) model is analyzed as a means for validating the model and identifying areas for improvement. Two separate CFD models were developed. One was analyzed with conjugate heat transfer...

The study of cold leg thermal stratification in APEX-CE

Creator:

Antoine, Stephanie Y. L. Antoine

Abstract:

This research presents an analysis of thermal stratification in the reactor cold leg of the Advanced Plant Experiment-Combustion Engineering (APEX-CE). This phenomenon may be a precursor leading to a Pressurized Thermal Shock (PTS) event in a nuclear power plant. This work was performed in support of the U.S. Nuclear Regulatory...
