ABSTRACTA realistic computer model for polymorphic crystallization under isothermal and nonisothermal conditions, which takes proper account of time-dependent nucleation behavior and cluster-size-dependent growth, is presented. A new correction to the standard Johnson-Mehl-Avrami-Kolmogorov (JMAK) statistical analysis that takes account of finite sample size is incorporated to simulate data taken from fine particles and nano-structured materials. Model predictions compare well with experimental data obtained from calorimetric studies of the polymorphic crystallization of lithium disilicate glass. The computer model is employed to evaluate commonly used methods of analysis for calorimetric data and to suggest new approaches for extracting kinetic parameters.

Abstract Biofluids such as blood, as well as other structured materials, exhibit rather complex rheological behavior. In this paper, starting from a first order kinetic model introduced by Soong et al., we developed a constitutive equation and studied its applicability to model biofluids. In particular, we studied the cases of steady shear flow, hysteresis, yield stress and small amplitude oscillatory flow. Model predictions were successfully compared with experimental data on complex materials such as blood and a penicillin suspension.
