Course Goals

 

Students who complete this course should be able to:

 

1. Understand why the numerical value of a variable is not meaningful until it is compared with a standard of the same dimension and how this leads to procedure of dimensional analysis which produces dimensionless parameters that define the fundamental characteristics of physical problems.

2. Understand shear and normal stresses in a flowing fluid and describe these mathematically.

3. Understand how pressure, gravity, moving surfaces and surface tension act on a fluid to deform it and possibly cause it to flow.

4. Understand the physical basis and mathematical derivation of the differential equations for mass and momentum transport.

5. Be able to use the differential equations for mass and momentum to solve (steady) unidirectional flow problems.

6. Understand physical meaning and origin within the governing equations of dimensionless numbers such as Reynolds, Froude and Weber.

7. Understand the use of physically-motivated approximations based on nondimensionalization of the governing equations to solve nearly-unidirectional flow problems.

8. Understand the physical basis and mathematical derivation of the macroscopic equations for mass and momentum transport.

9. Understand and be able to use macroscopic balances to solve problems for cases that are well-defined and also slightly ill-defined.
