Intermediate Heat Transfer

ME 50500 / 3 Cr. (3 Class)

Heat and mass transfer by diffusion in one-dimensional, two-dimensional, transient, periodic, and phase change systems. Convective heat transfer for external and internal flows. Similarity and integral solution methods. Heat, mass, and momentum analogies. Turbulence. Buoyancy-driven flows. Convection with phase change. Radiation exchange between surfaces and radiation transfer in absorbing-emitting media. Multimode heat transfer problems.

Textbooks

F. P. Incropera and D.P. Dewitt, Fundamentals of Heat and Mass Transfer, Wiley, Sixth Edition, 2006. E.R.G. Eckert and R.M. Drake, Analysis of Heat and Mass Transfer, McGraw Hill, 1972.

Goals

To enhance the student's understanding of energy and mass exchange processes and their relevance to practical and scientific apparatus and methods. 2) To increase the student's analytical skills and ability to cope with complex problems. 3) To provide the student with experience in treating multiple mode heat and mass transfer effects and in solving generalized, but realistic, engineering problems.

Outcomes

After completion of this course, the students should be able to:

  1. Build on an existing undergraduate background in heat transfer. [a,e]
  2. Explain the physical origins and modes of heat transfer and establish the relationship of these origins to the behavior of  thermal systems. [a,e]
  3. Derive partial differential equations for conduction and convection problems from first principles (conservation equations). [a]
  4. Solve partial differential equations (analytically, when possible, and reasonably approximately) of selected conduction and convection problems. [a,e]
  5. Solve external and internal flow convection problems for geometries such as tubes, tube banks, packed beds etc. [a,e]
  6. Apply radiation concepts such as blackbody radiation, view factor etc. to problems involving a participating medium.[a,e]
  7. Perform the kind of engineering analysis (using numerical or empirical methods) that, even though not exact, still provides useful information concerning the design and/or performance of a system or process.[a,c,k]
  8. Identify a research problem in one area of heat transfer, conduct literature search and develop an analytical or numerical approach related to the identified problem and report in a research paper format. [k,j,g]
