Multiphase Flow Dynamics 4: Turbulence, Gas Adsorption and Release, Diesel Fuel Properties

This book, Volume 4, is devoted to turbulence in multiphase flows as well as selected subjects in multiphase fluid dynamics that are very important for practical applications but could not find place in the first three volumes of this work. The state-of-the-art of turbulence modeling in multiphase flows is presented. First, some basics of single-phase boundary layer theory, including important scales and flow oscillation characteristics in pipes and rod bundles, are presented. Then the scales characterizing dispersed flow systems are presented. The description of the turbulence is provided at different levels of complexity: simple algebraic models for eddy viscosity; algebraic models based on the Boussinesq hypothesis; modification of the boundary layer shear due to modification of the bulk turbulence; and modification of the boundary layer shear due to nucleate boiling. Then the role of the following forces on the mathematical description of turbulent flows is discussed: the lift force; the lubrication force in the wall boundary layer; and the dispersion force. A pragmatic generalization of the k-eps models for a continuous velocity field is proposed, covering flows in large volumes and flows in porous structures. Its large eddy simulation variant is also presented. A method of how to derive source and sink terms for multiphase k-eps models is also presented. A set of 13 single- and two-phase benchmarks for verification of k-eps models in system computer codes are provided and reproduced with the IVA computer code as an example of the application of the theory. This methodology is intended to help other engineers and scientists to introduce this technology stepby- step into their own engineering practice
