AME 30334: Heat Transfer

CATALOG DATA:
An introductory course covering three modes of heat transfer: steady and unsteady conduction, elementary boundary layer analysis for laminar and turbulent convection and the basic theory of radiation.

PREREQUISITES:
AME 20231, AME 30331

TEXTBOOK:
Incropera, F.P. and De Witt, D.P., Fundamentals of Heat and Mass Transfer, John Wiley and Sons, New York, 5 th Edition 2002.

COURSE OBJECTIVES :
This course is designed to have students become knowledgeable in: 1) steady and unsteady one- and two-dimensional heat conduction, 2) internal and external convection, 3) basic concepts of radiation. In addition, they should develop problem solving skills in energy-related areas and understand the role that heat transfer plays in everyday life.

TOPICS COVERED:

• Introduction – Modes of Heat Transfer
• Steady 1-D Conduction
• Steady 2-D Conduction
• Transient Conduction – Analytical Methods
• Transient Conduction – Numerical Methods
• Convection – Basic Concepts
• Boundary Layers
• External Flow
• Internal Flow
• Free Convection
• Radiation – Basic Concepts
• Blackbody Radiation
• Radiation Exchange – View Factors

SCHEDULE:
This course meets 3 times a week for 50 minutes each meeting.

CONTRIBUTION TO PROFESSIONAL COMPONENT:
This course represents a balance between engineering science and design. Approximately 80% of the course is engineering science and 20% engineering design in the form of a design project. The Novotny Award is given for best design in this course.

CONTRIBUTION TO PROGRAM LEARNING OUTCOMES AND ASSESSMENT:
The course uses lectures, homework and a project to enable the students to be able to:

• demonstrate basic knowledge of heat transfer by understanding:
• differences between conduction, convection and radiation;
• basic differential equations for heat transfer;
• thermal conductivity of materials;
• temperature varying conductivity;
• conduction through walls and composite walls;
• critical radius of insulation;
• heat transfer in fins;
• heat transfer coefficient;
• overall heat transfer coefficient;
• log-mean temperature differences;
• forced and natural convection correlations;
• Biot, Nusselt, Reynolds, Grashof, Rayleigh and Prandtl numbers;
• basic radiative heat transfer.
• use knowledge of all modes of heat transfer and write a computer program to address and analyze a design problem for different choices of design parameters.

In order to assess the student’s progress towards achieving the Learning Outcomes, a number of homework problems are assigned, graded and handed back to the students. All examinations are graded by the instructor and solutions are posted on a web site. A design project report is required from each student and graded by the instructor.
