Heat Transfer

Catalog description

Steady state and transient heat transfer by conduction, laminar and turbulent convection, film condensation and boiling, and by radiation. Combined heat and mass transfer by diffusion and convection. The analysis and design of heat exchangers for process heat transfer. Typically offered Spring. Prerequisite(s): ME 30500 FOR LEVEL UG WITH MIN. GRADE OF D- AND ME 31200 FOR LEVEL UG WITH MIN. GRADE OF D- AND ME 31300 FOR LEVEL UG WITH MIN. GRADE OF D- Course Learning Outcomes 1. Formulate typical 1-D heat transfer differential equations with internal sources or for fins; apply boundary conditions; non-dimensionalize; and solve. 2. Understand the concept of thermal resistance and be able to manipulate strings of resistances as they may apply in real 1-D problems to get the overall resistance. 3. Use 1-D transient conduction charts in the solution of problems; identify transient problems for which the semi-infinite solution applies. 4. Recognize and treat the lumped capacitance limiting solution for transient conduction problems. 5. Formulate and solve conduction problems numerically. Included in this are transient and steady-state problems and problems with a variety (e.g. insulated, constant temperature, specified heat flux and convective) boundary conditions. 6. Have a physical sense of the boundary layer concept. Understand, in an overview sense, the role of the boundary layer in convective heat transfer problems. 7. Apply appropriate design correlations for the variety of convective heat transfer problems. This includes internal and external forced flow and natural convection situations. 8. Have basic understanding of the causes/ types of boiling/condensation phenomena. The ability to apply basic correlations in computations related to these situations. Recognize and solve problems involving heat exchangers and be able to determine when the Effectiveness-NTU and when the F-LMTD methods of analysis are called for. The student should be able to apply both of these methods in the solution of real problems. 9. Develop an understanding of the concept of view factor in radiation. This includes black as well as gray exchange. Have a basic understanding of the role of emissivity in radiative problems. View Class Schedule
