Course Description

119-Convection Heat Transfer Coefficient Estimation

Convection heat transfer takes place whenever a fluid is in contact with a solid surface that is at a different temperature than the fluid. This course gives background on Newton's law of cooling, a brief description of the difference between natural convection and forced convection, a discussion of the dimensionless numbers used in convection heat transfer correlations, and an introduction to some of the typical configurations of interest for convection heat transfer. Then the rest of the course is devoted to presentation of correlations and example calculations for estimating natural convection and forced convection heat transfer coefficients. A spreadsheet that will assist in making these calculations for either turbulent or laminar pipe flow is included with the course.

The overall objective of this course is to prepare those completing the course to calculate heat transfer coefficients for a variety of physical configurations of forced convection and natural convection. A more detailed list of learning objectives is included in the course document.

The written course material and references are very good, simple and easy to understand. Several of the example calculations are incorrect however, and should be corrected.
Based on your comments, the author has proof read and edited the course document. Thank you for your observations.

Generally good material and presentation Noted several issues: Use of "slugs" not generally used in either US or SI systems.Would lose dimensional consistency if viscosity units in feet although values same in both viscosity units Example 6 on P.23 divides length in feet by 12. The use of 12 should only be if cylinder diameter was expressed in inches Use of the term "characteristic length not fully defined for turbulent flow - as used in test question 12 this "length" is a an equivalent diameter

This was an excellent course and very well written. I will definitely use this course as a reference for any future heat transfer calculations.

A good base course for someone who does very little of these types of calculations during the regular course of work.
I re-learned a lot of information from my educational years and it was a great help.
The spread sheet was very well set up but could have had a little more interaction between the course problem examples and the spread sheet.

This is a good refresher course for convection heat transfer. Forced and natural convection through and over pipes, plates, and spheres are discussed. An excel download is available for these examples

This course was very comprehensive and very clearly presented. For section 10 on non-circular ducts, I wonder if Dr. Bengtson had considered the section "Fluids Flowing in Annuli" in Kern's book "Process Heat Transfer". Kern states that the equivalent diameter for heat transfer should be (D2 squared - D1 squared) /D1 because the outer perimeter of the larger pipe is not involved directly with heat transfer; Kern states that the equivalent diameter is (D2 - D1) for frictional pressure drop calculations. In Dr. Bengtson's example #5, using Kern's suggestion gives: DH = 2.33, Re = 29,705, f = 0.0237, NUo = 193.9, NUD = 201.43 and h = 342.35. For design, using Kern's DH is more conservative. Note also that in the solution to example #5, the spreadsheet results for heating show that NUo per correlation #3 = 95, NUD = 99 and h = 390 rather than the results presented in the course. Overall, this is a very worthwhile and very well written course!

Easy to read and understand. The spread sheet is not very useful outside this course as it should include a spread sheet for properties of fluids other than water.

Extremely clear writing and logical flow. The test didn't insult me but also wasn't complicated. Useful summary of multiple correlations -- the material is a helpful refresher for the occasional heat transfer calc I have to do.
