A constitutive equation for creep in glassy polymers and composites
The creep of polymethyl methacrylate was investigated in four-point flexural loading mode. Measurements were taken at temperatures from 8$\sp\circ$C to 55$\sp\circ$C, time periods up to 450 hours and stresses ranging from ...
Contact angle hysteresis and the energy principle
Experimental evidence suggests that contact angle hysteresis is related, in some cases, to surface roughness or heterogeneity on a microscopic scale. This work investigates the effect of periodic roughness or heterogeneity ...
EQUIVALENT CONTINUUM MODELS FOR NONADIABATIC MONOLITH CATALYTIC REACTORS
An equivalent continuum approach was used to model the heat transfer in the array of channels of a non-adiabatic monolith reactor. The equivalent solid thermal conductivity in the transverse direction was derived for ...
The selective hydrogenation of 1,3-butadiene in the presence of n-butenes over supported palladium catalysts
The selective hydrogenation of 1,3-butadiene in the presence of n-butenes over supported palladium catalysts, an industrially important reaction, was investigated at atmospheric pressure between 308K and 393K. The study ...
A method for improving equations of state near the critical point. (Volumes I and II)
This thesis develops better methods of predicting the thermodynamic properties of both pure components and fluid mixtures in the critical region. Accurate nonanalytic equations of state have been developed for carbon ...
