Experimental and Theoretical Study on Biaxial Normal-Shear Bonding Strength at Interface between Elastic/Elastic, Elastic/Viscoelastic and Viscoelastic/Viscoelastic Materials
DownloadFall 2012
Bi-material interface is often observed in many advanced materials and structures. Measurement of the interface bonding strength is more challenging than the measurement of pure tensile or shear strength of a homogeneous material because of the presence of the stress singularity at the interface...

Experimental evaluation and model development for analysis of pressure drop in the lungs of children
DownloadFall 2018
Airway resistance describes the ratio between pressure drop and flow rate through the conducting respiratory airways. Analytical models of airway resistance for tracheobronchial airways have previously been developed and assessed without upper airways positioned upstream of the trachea. This...

Experimental Evaluation and Modeling of an In-duct Ultraviolet Germicidal Irradiation (UVGI) System for Bioaerosol Disinfection
DownloadSpring 2024
Airborne pathogen transmissions have played critical roles in the previous COVID-19 pandemic and various respiratory epidemics, such as influenza, severe acute respiratory syndrome (SARS), etc. Inhaling airborne pathogens can cause adverse health effects, resulting in respiratory infections,...

Object detection is an image processing technology to detection different classes of objects using computer vision, i.e. putting bounding boxes over objects from a camera video feed. A landmark detection method was the Viola-Jones Algorithm introduced in 2001. The object classifier in this...

Fall 2023
To enhance the aerodynamic performance of a vehicle, a fundamental understanding of the flow is required. This can be achieved through flow characterization of simplified models such as the Ahmed body. However, uncertainties regarding the topology of flow motions in the wake persist due to the...

Experimental Investigation of Carbon Black Properties Produced by the Thermal Decomposition of Methane in the Products of Premixed Flames
DownloadFall 2018
The thermal decomposition of methane is a technique used to manufacture hydrogen gas and carbon black. The physical properties of carbon black produced by the thermal decomposition of methane (TDM) in the O2-deficient gas products of two premixed flames (propane- or methane-air) were investigated...

Experimental investigation of drag reduction by polymer additives in a turbulent channel flow
DownloadSpring 2018
The addition of a minute amount of long-chain polymer molecules to a turbulent flow can cause a significant reduction of skin-friction drag in both internal and external flows. The explanation of interaction between polymers and turbulence remains the most difficult area of polymer flow...

Experimental Investigation of Heat Transfer and Pressure Drop of Pipes with Internal Roughness
DownloadFall 2022
In many industrial heat exchangers, it is desirable to improve the rate of heat transfer from a pipe wall to the fluid flow. This improvement is commonly made by adding some form of roughness to the pipe surface. However, the added roughness often leads to an increase in the pressure drop of the...
