The course will start with a theoretical support for the concept of "complex fluids" using knowledge of Fluid Mechanics, Thermodynamics and Statistical Physics. The course will then approach different classes of complex fluids: viscoelastic fluids, yield stress fluids, suspensions, molten polymer systems. Relevant practical examples (in relation to industrial applications and biology-health applications) will be given for each class of fluid. A short but systematic introduction to the rheological characterization of these fluids will follow. Different rather particular flows (for example Elastic Turbulence) concerning each class of fluids will be analyzed. Practical applications of complex fluid flows (mixing, heat transport etc.) will be presented.
Towards the end of the course, a short introduction to numerical simulations of complex fluid flows will be made.
As a new element, we will introduce basic Molecular Dynamics methods in the context of complex fluids at the nanoscale (I will illustrate numerical simulations using the open-source software Gerris and Basilisk for the macroscopic scale).
The handwritten lecture notes will be gradually (as we move on through the course) uploaded here:
Part 1, Part 2, Part 3, Part 4
Part of the course will follow some sections from my book entitled Transport Phenomena in Complex Fluids.
This is a short "crash" course (12 hours) mean to introduce the basic concepts of Fluid Mechanics. The introductory concepts taught in this course will provide the students the basis for more advanced graduate courses such as Hydrodynamic Turbulence, Transport Phenomena in Fluids, Complex Fluids.
NEW: After exchanging with some of the students in the class, I am tempted to spend about half of the last lecture to give the students an overview of several research topics being currently studied in our team. Among these, I will exemplify some numerical simulations of seemingly "basic" fluid dynamics problems using the open source flow solver Gerris developed by Dr. Stephane Popinet.
EXAM
The course will conclude with a written exam of 1.5 hours composed of two parts. For the first 30 minutes, a set of brief theoretical questions strictly related to the material covered during the course will have to be answered. No sources of information will be allowed during this part. During the remaining hour, the students will solve a set of exercises related to the topics covered through the course. For this part, the students may use any book they feel appropriate and/or the lecture notes handed by the instructor. No computers, mobile phones, calculators will be allowed during the entire duration of the exam. The exams will be graded between 1 and 20 with the passing grade being 10.
This is a short "crash" course (11 hours) meant to introduce the Thermal Enginnering students to the rather broad field of rheology and hydrodynamics of Complex Fluids in both isothermal and non-isothermal settings. Whereas I will teach a number of fundamental concepts (involving some math in several instances), the course will be mainly geared towards practical questions/applications such as: "why the warm butter is easier to spread on a slice of bread than the cold one", "how do we efficiently mix the cream our coffee", "what polymer processing operation would be useful to produce a plastic Coca Cola bottle" and so on.
The lecture notes can be downloaded here. The printed version of the course notes will be handed to you.
EXAM
The exam will be an open-book exam meaning you may use any printed information (books, lecture, notes or any other materal you deem useful). However, several extra rules will be enforced. No electronic devices (mobile phones, calculators, computers etc.) may be used during the exam. The examination is INDIVIDUAL meaning that collaboration among students is strictly forbidden. The instructor will answer during the exam only "semantic" questions, that is questions related to the meaning of the exercises. Upon request, the instructor may translate parts of the exercises in French. This will be done in a loud voice, so everyone can hear - no "private" explanations will be given. Last, rescheduling the exam (if needed) can only be done with the responsible of the teaching department. Then instructor takes no responsability on that.
