A Compact Introduction to the Numerical Modeling of Multiphase Flows
This report represents the handouts of an eight hour lecture held on occasion of the ”International Summer School on Computational Modeling of Combustion & Multiphase Flows in Energy Systems”. This summer school took place in Neptun-Olimp, Romania, in the period of July 21 – 25, 2003. The purpose of this report is to give students that are already familiar with the physics and numerical computa...
متن کاملModelling Compressible Multiphase Flows
We give in this paper a short review of some recent achievements within the framework of multiphase flow modeling. We focus first on a class of compressible two-phase flow models, detailing closure laws and their main properties. Next we briefly summarize some attempts to model two-phase flows in a porous region, and also a class of compressible three-phase flow models. Some of the main difficu...
متن کاملMultiphase Cooling Flows
I discuss the multiphase nature of the intracluster medium whose neglect can lead to overestimates of the baryon fraction of clusters by up to a factor of two. The multiphase form of the cooling flow equations are derived and reduced to a simple form for a wide class of self-similar density distributions. It is shown that steady-state cooling flows are not consistent with all possible emissivit...
متن کاملUltrasonic Diagnosis in Multiphase Flows
We present here a new ultrasonic diagnosis technique in natural, porous rocks. This method, based on the ultrasonic velocity changes, allows us to measure the transient spacial distribution of two liquids (water and oil) in a sandstone.
متن کاملThe Measurement of Volume Fraction and Velocity Profiles in Vertical and Inclined Multiphase Flows
The nature of solids-liquid flows often results in non-uniform profiles of solids volume fraction and axial solids velocity across the flow cross-section. In order to measure the solids volumetric flow rate in these situations it is necessary to measure the profiles of the local solids volume fraction and axial solids velocity and to obtain mean values of the solids volume fraction, solids axia...
