WHOLE ORGAN FREEZING AND THAWING HEAT TRANSFER AND THERMAL PROPERTIES.
Abstract
A number of freezing experiments were performed with bovine liver samples, using liquid nitrogen and dry ice-acetone as refrigerants. The experimental time-temperature results were compared to predicted values obtained from a numerical analysis for an idealized liver slab. Several improvements in the thermal conductivity apparatus were made. The system involved was checked using water. Also some preliminary thermal conductivity measurements for bovine kidney at room temperature and at -45F were obtained. The heat capacities of bovine suet, heart muscle, and brain were measured at liquid nitrogen temperatures with the thermal gradient calorimeter; preliminary measurements for bovine kidney and pure NRG protein were also obtained.
