Theoretical prediction of the effect of heat transfer parameters on cooling rates of liquidfilled plastic straws used for cryopreservation of spermatozoa

Abstract: Heat transfer plays a key role in cryopreservation of liquid semen in plastic straws. The effect of several parameters on the cooling rate of a liquid-filled polypropylene straw when plunged into liquid nitrogen was investigated using a theoretical model. The geometry of the straw conta...
