Fluid Mechanics for Mechanical Engineers

## Objectives

[edit | edit source]

The course material is prepared for the Mechanical Engineering students of Ozyegin University.

By the end of this course, the students, who have no background in fluid mechanics, are expected

1\. To get acquainted with the following fluid flow phenomena.

* Newtonian and non-Newtonian fluids,
* Fluid statics,
* Laminar and turbulent flows,
* Separated flows,
* Multi-phase flows (Sprays, Boiling, Cavitation, etc.)
* Aerodynamics,
* etc..

2\. To have theoretical understanding of fluid flow. This will be achieved by giving the mathematical fundamentals of integral and differential modeling of fluid flows for the conservation laws of mass, momentum and energy.

3\. To classify different types of fluid flow phenomena and derive the necessary non-dimensional parameters.

4\. To apply fluid mechanics knowledge on real life problems by simplifying the governing equations for peculiar flows and solving them.

Moreover, students have the chance to see the direct application of the content in the research and development work conducted by the lecturer.

## Motivation of studying fluid mechanics

[edit | edit source]

Fluid mechanics is a fundamental subject of many disciplines of engineering and natural sciences. It is involved, for example, in mechanical engineering, chemical engineering, aerospace engineering, biomedical engineering and, also, in material sciences. As a matter of fact, it is a field where multiple physical effects can be met. Extrusion of polymers, crystal growth, die casting, car and aircraft aerodynamics, flow in heat exchangers, irrigation systems, heating, cooling and ventilation systems, pumps and turbines are technological examples where fluid mechanics plays a very important role. Fluid mechanics knowledge is necessary to understand the nature of flowing medium. This knowledge certainly help us to develop new devices and processes. Furthermore, application of the methods used in the fluid mechanics discipline in other engineering fields might be beneficial.

## Basic components of the course

[edit | edit source]

This course is dominantly a theoretical one. However, examples are provided in the form of visual media and laboratory experiments. Exercises are made and homeworks are given so that students get acquainted with the theoretical approach in fluid mechanics. In the last part of the course, relevant examples of research work, which are conducted by the lecturer are provided.
