This thesis presents a study of macroscopic thermodynamic concepts used to evaluate advanced design modifications to the internal combustion engine. A set of analytical solutions is developed which is used to determine the thermal efficiencies of such designs based on modified i…

A transient heat and mass transfer model was developed to predict ceiling heat gain/loss through the attic space in residences and to accurately estimate savings in cooling and heating loads produced by the use of radiant barriers. The model accounted for transient conduction, c…
