ENME 442 Machine Design (3)

Catalog Description:

The analysis of design of machine elements including fatigue-failure analysis of shafts, springs, screws, brakes, clutches, chains, belts, welds & rivets, lubrication of journals, ball & roller bearings, and spur, helical, bevel and worm gears. 

Course Objectives:  At the completion of the course, students will have demonstrated the

  • Ability to apply mechanics of materials to machine elements,

  • Ability to apply static load criteria to ductile and brittle materials, 

  • Ability to apply fluctuating load criteria, stress concentrations to ductile materials,

  • Ability to apply high cycle cumulative fatigue failure equations, 

  • Ability to apply mechanics of materials, appropriate failure criteria, and specific design equations to the following machine elements:  shafts, springs (helical and non-helical), threaded fasteners, belts, clutches, brakes, chains, welded and riveted connections, lubrication and journal bearings, roller element bearings,

  • Knowledge of process of registration, and

  • Ability to design a mechanical component or system

A typical design project is a journal bearing as shown being tested in the ENME 447 lab.

ENME 443 Design of Thermal Components (3)

Catalog Description:    

Design of individual components of thermal systems.  Economic tradeoffs in sizing, choice of materials, number of passes, and other design criteria. Examples of heat exchangers, refrigerators, steam cycle components, and modern innovative concepts.

Course Objectives: At the completion of the course, students will have demonstrated the ability to

  • Apply principles of fluid dynamics, thermodynamics and heat transfer to the study of refrigeration cycles, turbo-machinery and other thermal components such as heat exchangers, HVAC coils, pipe and duct networks,

  • Analyze and explain the operation of different refrigeration cycles, psychrometric processes, pumps and fan,

  • Design  HVAC coils, shell and tube heat exchangers to meet the engineering and economic constraints,

  • Analyze and select pumps and fans and design the piping network, duct systems, and

  • Relate fundamental laws to useful engineering models and, in turn, link these models to design decisions, when confronted with design and open-ended problems. In providing these solutions, demonstrate the knowledge of contemporary issues such as global warming, ozone depletion, and ethical responsibilities and impact of global and societal context through adherence to the relevant codes and standards and broad education. Students address these issues through design of shell and tube heat exchangers, design projects involving innovative systems such as energy recovery devices, dedicated outside air systems (DOAS), fuel cells, combined heating and power (CHP). Design projects having these systems save energy, and reduce global warming and ozone depletion, confirmed by the quantitative estimates.

ENME 450 Mechanical Engineering Design Project (3)

Catalog Description:    

Capstone mechanical engineering design experience; design of a thermal and/or mechanical system; consideration of engineering standards and realistic constraints that include most of the following considerations: economic, environmental, sustainability, manufacturability, ethical, health and safety, social, and political; team and/or individual application of the design process; oral presentations and written design report required.

Course Objectives: At the completion of the course, students will have

  • Applied fundamental engineering principles and approaches (learned in prerequisite courses) to design a thermal and/or mechanical system,

  • Demonstrated an awareness of the professional registration process,

  • Worked effectively as a team (if team-based work is assigned),

  • Generated adequate written documentation of their design,

  • Demonstrated an understanding of the multiple factors that influence a design, the tradeoffs that may be required, and the impact of design decisions and realistic constraints.

A water turbine system as shown below was designed and tested during the spring 2003 ENME 450 course.
