Instruction Goal
To teach students a basic understanding of the laws of heat and mass transfer and to provide the opportunity to apply these laws to simple engineering situations.
Outcomes
After completion of this course, the students should be able to:
- Explain the physical origins of heat and mass transfer, identify important modes of heat transfer in a given situation, and make appropriate assumptions. [a]
- Calculate heat transfer rate and temperature distribution in steady-state one-dimensional heat conduction problems. [a,e]
- Sketch temperature profiles in one-dimensional heat transfer, showing the qualitative influence of energy generation, non-planar geometry, or time dependence. [a]
- Calculate the rate of steady heat transfer in fins, and unsteady heat transfer in lumped-capacitance and semi-infinite solid problems.[a,e]
- Calculate the rate of mass diffusion in one-dimensional problems, with or without bulk motion effects. [a,e]
- Explain the terms in the governing equations for convective heat and mass transfer. [a]
- Estimate convective transfer rates on the basis of geometric and dynamic similarity, and analogy between different convective transport processes. [a,e]
- Calculate heat and mass transfer rates in external and internal flows, including flat plates, cylinders, pipes, heat exchangers, and free convection at vertical surfaces. [a,e]
- Explain how radiation can be described based on its wavelength, source, and direction, and explain the basic concepts of blackbody radiation, reflectivity, emissivity, and absorptivity for surface radiation. [a]
- Apply the laws of radiation to compute heat transfer rates for surfaces, such as black bodies and diffuse gray surfaces, with appropriate approximations. [a,e]
- Calculate and use the view factor for simple surface combinations, and the total emissivity for surfaces. [a,e]
