ENME Undergraduate Course Description: ENME 331

For more information about the Undergraduate Program in Mechanical Engineering, contact: Dr. Sami Ainane Director of Undergraduate Programs ainane@umd.edu

ENME 331- Fluid Mechanics I
Mechanical Engineering

Designation: Required

Course Description:

Principles of fluid mechanics. Mass, momentum and energy conservation. Hydrostatics. Control volume analysis. Internal and external flow. Boundary layers. Modern measurement techniques. Computer analysis. Laboratory experiments.

Prerequisite(s): ENES 221 and ENME 232

Textbooks

• Fundamentals of Fluid Mechanics, 4th Ed. by Munson, Young and Okiishi, John Wiley & Sons, Inc., 2002

Course Objectives

In this course, the student will develop and/or refine the following areas of knowledge:

• General engineering problem formulation, organization, solution
• Mathematical descriptions of fluid systems, and how to simplify generalized conservation equations for a fluid in an appropriate manner to apply to specific problems
• Develop skills in self-taught learning through completing of a semester project. The main topic required for the project (typically dimensional analysis) is not lectured in class, but supporting materials are provided and all questions are discussed and answered. Project is deliberately open-ended to foster creativity in problem solutions and application of learned material in a more realistic environment.
• Develop skills in technical writing through detailed technical reports on semester project. Each report is given extensive feedback by the instructor, and used as a draft for successive version. Feedback is given both on technical content as well as organization and presentation of material.

Topics Covered

• Introduction, definition of a fluid, fluid properties
• Eulerian vs. Lagrangian frame of reference, substantial derivative
• Fluid kinematics, streamlines and streamfunctions
• Differential form of the conservation equations
• Hydrostatics (manometers, forces on flat plates, forces on curved surfaces, buoyancy)
• Derivation and use of Bernoulli’s equation, pitot-static tubes
• Control volume analysis
• Exact solutions of the Navier-Stokes equations
• Pipe flow analysis, turbulent flow
• Flow over immersed bodies, boundary layers, lift and drag
• Dimensional anaylsis is covered through an assigned student project

Class/Laboratory Schedule

• Two 50-minute lecture sessions per week. (full class)
  
• One hour and 50-minute studio per week (30-student sections)
  
• Two in-class examinations plus a final examination.

Contribution to professional component

• Math and basic science 1.0 (units)
• Engineering topics: 2.0 (units)
• Does this course contain design experience? Yes

Relationship to program outcomes

ENME 331 contributes directly to the following specific Mechanical Engineering Program Outcomes of the ME Department:

1. A knowledge of mathematics, physical science, and engineering science.
2. The ability to apply mathematics, science, and engineering knowledge to solve mechanical engineering problems.
3. The ability to work in teams effectively to address practical engineering problems.
4. The ability to communicate effectively in presentations and in writing.
   
5. The ability to design and conduct experiments and to interpret and generalize from the results.
6. The ability to engage in life-long learning and the ability to conduct research using external sources.
