Course Description:
Advanced Fluid Mechanics for Processes - 5EUS5MFA Goals To give advanced knowledge of two-phase flows, two-phase thermohydraulics, electrohydrodynamics, magnetohydrodynamics as well as bulk rheology. To provide a background level in using modeling or designing tools for processes involved in a diversity of technological applications: solar or nuclear energy with reactors of 3th generation (ATMEA, EPR), 4th generation (ASTRID) and even 5th generation (ITER), nuclear waste management, oil engineering, food or drug engineering, metallurgy, engineering of many processes involved in sustained environment. Contact Laurent DAVOUST Content This module gathers courses which contribute together to the development of fluid processes at micro and macro scales: two-phase flows (Henda Djeridi), two-phase thermohydraulics (Fabrice Francois), bulk rheology (Laurent Jossic), electro- and magneto-hydrodynamics (Laurent Davoust, Yves Fautrelle and Olivier Doche). Theses courses aims at introducing modern challenges of fluid mechanics, this is to say: complex flows with a second dispersed or stratified phase, non-newtonian flows, multiphysics flows with strong coupling with electrostatics or electromagnetism. The module is organized according to a lecture series, some of the lectures are mandatory while other ones are optional. MANDATORY COURSES: Two-phase flows (Course: 10H) Topics: i) dynamics of particles (drag force, deformability, trajectory instabilities, mass added force, Basset (history) force, ii) BBOT equation, iii) lift forces, particle-particle and particle-wall interactions, iv) particle-turbulence interaction, averaged modeling of dispersed two-phase flows. ABOUT US STUDIES RESEARCH INTERNATIONAL COMPANIES STUDENT LIFE Number of hours Lectures : 46.0 Tutorials : 13.0 Laboratory works : 8.0 ECTS : 5.0 Page 1 Two-phase hydraulics (Courses: 18H, Training sessions: 8H) i) Two-phase flows in horizontal or vertical ducts with special focus on flooding and flow reversal phenomena, ii) measurement methods in two phase flows (measurement of void fraction, flow rates, phase velocities…), iii) mass and momentum balances in two-phase flows especially in ducts, iv) two-phase balances, surface balances, closure equations in two phase flows with special focus on drift flux and averaged equation-based modeling, v) introduction to heat transfers, boiling, pool boiling, critical heat flux, vi) vapor condensation, films or droplets. ONE OPTIONAL COURSE TO SELECT AMONG: Rheology (Course: 18H, Training sessions: 6H) 1. Recalls on continuum mechanics, Newton and Hooke models. 2. Non-newtonian models: viscoelasticity, thixotropy…, 3. Measurement methods of fluid materials: shear and dilatational rheometry 4. Flow modeling: dimensionless numbers and invariants 5. Constitutive laws for materials processing, linear and non linear domains, rheometry. Electro- and MagnetoHydrodynamics (Course: 18H, Training sessions: 6H) Magnetohydrodynamic (MHD) flows and applications to pumps, agitators, levitators are presented as well as electrohydrodynamics (EHD) and its application to fluid micro-processes such as electro-sprays, electro-osmosis or electro-phoresis. MHD part: steady MHD flows are distinguished from AC MHD. The basic equations are presented, with particular emphasis on the influence of the Lorentz body force in the Navier-Stokes equations, the conservation of the electric current density. The dimensionless numbers of Hartmann and magnetic Reynolds are introduced. MHD in this course is thought of as weakly coupled (vanishing Reynolds number). Hartmann flows are calculated with a special focus on the electrical activity of the boundary layers which can govern velocity scale in pipe flows. The impact of geometry or magnetic field non-uniformities upon MHD flows is introduced. In the case of AC MHD, the electromagnetic boundary layer, the skin thickness effect and electromagnetic levitation are detailed. EHD part: The equations of electrohydrodynamics are presented with Gauss's law in volume and fluid interfaces, conservation of electric charge, the balance between mechanical and electrical tensors at interfaces (Taylor-Melcher EHD), and finally electrowetting. Are also presented: the electric double layer thickness and Debye electrokinetics. Each part is doubled with a training session based on numerical simulations to illustrate most singular properties of MHD or EHD flows.

The content taught in this course is similar in difficulty to material taught in a graduate level class. The prerequisite for this class is ME 335. The student must take ME 335 at ISU PRIOR to taking this class at Grenoble INP. This course will not come back as a mechanical engineering technical elective if the student has not taken ME 335 at ISU before taking this class at Grenoble INP.
