Research focus was the exploration of thermal wave propagation and temperature distributions in packed beds comprised
of encapsulated phase-change materials. The objectives of the work were to develop models that can be used to predict the
propagation of melting and freezing fronts, as well as describe the temperature distribution across the bed. A test system
was utilized in investigating the thermal characteristics of the system. Air was used as the heat transfer fluid. Charging
operations required heating the air prior to it being supplied to the bed. Discharging operations, employed to extract
thermal energy from the bed, required cooling the air prior to delivery at the bed. Temperature data supported the
hypotheses and mathematical models used to predict the behavior of both the thermal as well as the phase-change fronts
advancing through the bed during the melting and freezing processes. Test data indicated the time of arrival for the phase-
change wave front, in terms of the time that phase-change begins and ends, and was used to estimate the velocity of both
the melting and freezing fronts. Comparison of test data for the phase-change and thermal wave front velocities, to values
resulting from the theoretical model developed for wave front velocities, resulted in an acceptable correlation, particularly
for the melting and freezing processes. The velocities of isotherms in the partial phase-change region were also identified,
and a model was developed to predict velocities as a function of the ratio of the isotherm velocity to the Darcy velocity,
and the degree to which the phase-change material is solidified.

UNIVERSITY OF UTAH, Department of Mechanical Engineering-Ergonomics and Safety
MS Thesis - Conducted an ergonomic study to assess the biomechanical and psychophysical affects resulting from subject’s
exposure to different diameter handwheels in varied orientations, under varying loads and turning rates, during handwheel
turning operations. Employed a biomechanical model developed by the University of Michigan to simulate subject postures
and to predict reactions in terms of moments at the elbow and shoulder joints and compressive forces in the lower back at the

L5/S1 vertebral interface. The output generated by the biomechanical model in terms of reacted elbow and shoulder
moments and lower back compressive forces, based on the forces and postural inputs emulating the specified handwheel
turning configurations and actual posture of each of 20 subjects, were compared to the subject’s preference of handwheel
diameter in order to establish the degree of correlation between handwheel diameter and the smallest values for the reacted
elbow and shoulder moments and compressive forces in the lower back.
