Objective A student achieving a passing grade in this course will be able to do basic calculations involving heat and mass transfer as is typical for a mechanical engineer. The objectives of the course are to cover the basic principles of heat transfer, to develop an intuitive understanding of heat transfer by emphasizing the physics and physical arguments. This includes conduction, convection and radiation heat transfer as well as heat exchanger design. Students will understand the basic concepts of conduction, convection and radiation heat transfer. Students will understand how to formulate and be able to solve one and two dimensional conduction heat transfer problems. Solution techniques will include both closed form and numerical methods. Convection effects will be included as boundary conditions. Students will understand the fundamentals of the relationship between fluid flow, convection heat transfer and mass transfer. Students will apply empirical correlations for both forced and free convection to determine values for the convection heat transfer coefficient. They will then calculate heat transfer rates using the coefficients. Students will understand the basic concepts of radiation heat transfer to include both black body radiation and gray body radiation.
Content
Course Learning Outcomes 1 combine heat transfer, fluid mechanics and thermodynamics, as needed, to assess more complex systems and their components,
2 Develop representative models of laminar/turbulent, internal/external, free/forced convection problems and their solutions.
3 solve multi-mode heat transfer problems based on identified and assessed assumptions and conditions,
4 use the basic conservation equations to formulate heat transfer problems including multi-mode situations including conduction, convection and/or radiation
5 apply the conduction equation in rectangular, cylindrical or spherical coordinates to problems in transient and/or steady state conduction,
6 .Internalize the meaning of the terminology and physical principles associated with heat transfer,
