Concepts, units and sizes - 3FMT1002

Goal(s)

Learning outcomes :

• To know the phenomena and processes of fluid phase transfer at the molecular level: quantity of movement, mass and energy, and their analogy.
• To understand the theoretical elements of dimensional analysis that define dimensionless numbers (Prandtl, Schmidt and Lewis)
• To set about case studies: gaseous or liquid fluids, pure or mixed phases, calculation of dimensionless numbers based on the theoretical elements of the transfer process and dimensional analysis

Content(s)

Basic concepts of physics associated with fluid mechanics, energy and molecular scale transfer phenomena: quantity of movement, matter, energy.
Introduction to dimensional analysis and study of some dimensionless numbers.

Reminders: the fundamental quantities of physics and energy, and their units
Law of transfer of the quantity of movement at the molecular scale: viscosity of fluids.
Law of energy transfer at the molecular level: thermal conduction.
Law of transfer of matter at the molecular scale: diffusion of matter, transport balances, stationary and non-stationary diffusion.
Analogy of the laws of transfer: quantity of movement, heat, matter.
Dimensionless numbers of Schmidt, Prandtl and Lewis.
Introduction to dimensional analysis: matrix method.

Throughout the course, emphasis is placed on the comparison of data, formulas, the use of tables and graphs, the accuracy and precision of calculations derived from data and formulas, their comparison with data from graphs and value tables from different bibliographic sources.

Managed Works: course assimilation exercises and case studies.

L1 and L2 physics courses or equivalent at the undergraduate level in scientific classes (scientific preparatory classes, IUT, BTS)
