Transport coefficients of fluids

Meer over het boek

This monograph explores the density fluctuation theory of transport coefficients in simple and complex liquids, integrating the kinetic theory of liquids, the generic van der Waals equation of state, and modified free volume theory. These theories are crucial for calculating the density and temperature dependence of transport coefficients based on intermolecular forces. While nanoscience and bioscience dominate current scientific discourse, many fundamental aspects of condensed matter science remain unresolved or poorly understood, risking their neglect. The transport coefficients of liquids and gases, along with their thermophysical properties, represent a critical area within the macroscopic properties of molecular systems and statistical mechanics of condensed matter. A solid understanding of these properties is essential, even for nano- and biomaterials, which cannot be fully grasped without a foundation in macroscopic and molecular theories of transport. The systems in question involve a vast number of particles, making them complex and necessitating the use of statistical mechanics and macroscopic physics. The density fluctuation theory of transport coefficients adopts a fundamentally different approach compared to conventional kinetic theories of gases and liquids.
