Fluid mechanics

Course Description: Fundamental concepts and characteristics of basic fluids in fluid mechanics. Fluid statics (pressure variation and forces on submerged surfaces) and manometer applications. Fluid motion (Eulerian and Lagrangian descriptions of flow, Reynolds transport theorem and its applications for developing mathematical formulations for control volume statements of conservation of mass, momentum, and energy). Inviscid flow (differential analysis of fluid flow, Euler equations, Bernoulli equation, and potential flow). Viscous flow (stress-strain relationships, Navier-Stokes equations, and Couette and Poiseuille flows). Dimensional analysis and similarity. Viscous pipe flow (laminar and turbulent flow, friction factor, and flow in pipe networks). Boundary layer theory (boundary layer equations, boundary layer thickness, and calculation of drag and lift coefficients). Introduction to one-dimensional compressible flow.

Credit hours: 3

Prerequisites: ME 371

Objectives of the course :

– Introducing the student to the fundamental concepts and properties of fluids.
Provide the student with sufficient knowledge to understand and apply fluid statics equations to determine pressure changes and hydrostatic forces acting on surfaces submerged in static fluids.
– Enable the student to understand the Eulerian and Lagrangian descriptions of flow, and to use Reynolds' transport theorem to derive control volume formulations for the conservation of mass, momentum, and energy.
- Enabling the student to solve inviscid flow problems using Euler's and Bernoulli's equations.
Enable the student to understand viscous flow and its representative equations (Navier-Stokes equations), and how to simplify them to obtain some analytical solutions (such as Couette flow).
– Introduce the student to the method of dimensional analysis and how to apply it to fluid flow problems.
Enable the student to perform fluid flow analysis in pipes (simple pipes and pipe networks).
- Enable the student to understand boundary layer theory and its descriptive equations, and to solve some related problems.
