Course Outcomes

Fluid Properties

1. Understand viscosity as a fluid property and be able to compute shear stress involving Newtonian fluids. Understand the different types of fluids and the phenomena of surface tension and cavitation.

Pressure in Fluids

2. Understand the variation in pressure, and determine pressure at a point in a static gas or liquid. Be able to compute hydrostatic forces on fully and partially submerged surfaces, and be able to determine the location of the center of pressure.

Flowing Fluids

3. Understand field variables and be able to evaluate the local, convective, and total acceleration in flowing fluids. Recognize Lagrangian and Eulerian frames of reference. Understand pressure distributions normal to, and parallel to, streamlines in flowing fluids. Be able to appropriately apply Bernoulli's principle to fluid dynamic situations and recognize the limitations of this principle.

Conservation of Mass

4. Be able to derive the integral form of the conservation of mass principle from the Reynolds Transport Theorem and appropriately apply it to steady and unsteady flow situations with uniform or two-dimensional velocity distributions. Recognize and be able to utilize the differential form of conservation of mass.

Global Force/Momentum Balances

5. Be able to derive the integral form of the linear momentum principle from the Reynolds Transport Theorem and apply global force/momentum balances for stationary and constant velocity frames of reference with uniform or two-dimensional velocity distributions. Recognize the Navier-Stokes equations and solve them for simplified viscous flows.

Dimensional Analysis

6. Be able to determine appropriate dimensionless variables for a given dynamical situation. Understand the usefulness in presenting experimental data using dimensional analysis. Predict prototype analysis based on similitude and understand the pitfalls of modeling.

Mechanical Energy Equation

7. Understand the mechanical energy equation and be able to apply it to laminar and turbulent flow with minor and major losses through pipe networks.

Velocity Distributions

8. Understand and predict velocity distributions and boundary layer growth for flat plate boundary layers with laminar or turbulent flow. Understand flow separation, be able to predict skin friction and pressure drag for laminar and turbulent flows, and describe methods of drag reduction. Be able to determine Lift and explain how it is generated.

Form Drag and Flow Seperation

9. Be able to utilize the principles of fluid dynamics to analyze and solve real world flow phenomena. Be able to use structured techniques (e.g. The 5 Ps of problem definition) to develop an engineering problem statement based on real-world applications of fluid mechanics and apply structured problem solving techniques (e.g. SAFER to solve fluids engineering problems. Be able to methodically explore the possible solution space (e.g. using ConVerSAnT) for fluids problems.

Investigate Phenomena and Communicate Results

10. Be able to investigate elementary fluid dynamical phenomena experimentally, present experimental results graphically in figures in terms of appropriate dimensionless variables, and effectively communicate results in a formal technical document.
