Dr. Amber Krummel and her research team at Colorado State University (CSU) conducted a multi-phase experimental study to test whether low-frequency vibrational energy influences molecular interactions, crystallization, and interfacial behavior in petroleum fluids. The goal was to establish measurable, repeatable evidence of vibrational effects on nucleation processes, adhesion forces, and fluid phase stability.
Crystallization & Nucleation Studies
Researchers analyzed crystal formation patterns using high-resolution imaging and spectroscopy to determine whether vibrational energy disrupted paraffin and scale nucleation.
• X-ray microtomography and X-ray diffraction (XRD) measured structural evolution and molecular ordering in treated vs. untreated deposits.
• Differential Scanning Calorimetry (DSC) tracked thermal phase transitions, identifying modifications in nucleation energy barriers.
• Resonance Ultrasound Spectroscopy (RUS) assessed mechanical property differences, confirming structural changes in treated crystals.
Interfacial Adhesion & Molecular Organization Studies
Experiments evaluated changes in molecular interactions at fluid-solid interfaces, focusing on adhesion forces and molecular structuring.
• Vibrational Sum-Frequency Generation (VSFG) Spectroscopy revealed weaker interfacial molecular bonds, suggesting reduced adhesion tendencies.
• Surface Tension Analysis & Contact Angle Measurements quantified wetting behavior shifts, indicating reduced deposition potential.
• Computational Molecular Modeling simulated vibrational effects on molecular ordering, validating experimental findings.
Fluid Stability & Flow Behavior Studies
Viscosity and phase stability were tested to determine vibrational impacts on fluid rheology.
• Rheology & Thixotropy testing identified viscosity and shear response modifications, demonstrating improved fluid characteristics for better flow efficiency.
• Bulk Fluid Stability Analysis & Phase Separation Imaging showed emulsion behavior differences, which demonstrate improved oil-water separation efficiency.
• Fourier Transform Infrared (FTIR) Spectroscopy analyzed molecular composition shifts, detecting structural changes in hydrocarbon interactions.
