COURSE DESCRIPTION

This course is a study of thermal properties of materials, conduction through simple shape and composite materials free and forced convection, overall heat transfer coefficient, dimensional analysis, steady and unsteady state operations. Film and drop wise condensation, nucleate and film boiling of liquids (evaporation) students also learn heat exchangers types and design.

COURSE OBJECTIVES

 The student will be able to:

1.  Understand the basic concepts of conduction, convection and radiation heat transfer. 
2. Understand how to formulate and be able to solve one dimensional conduction heat transfer problemsusing Fourier’s Law for one-dimensional conduction of heat in solid for steady and unsteady state. 
3. Develop and apply conduction and convection thermal circuits. 
4. Choose and apply appropriate dimensionless correlations for external and internal flows to solve convection heat transfer problems. 
5. Calculate individual heat transfer coefficients inside conduits and outside bodies using literature correlations or from energy/material balance findings. 
6. Calculate overall heat transfer coefficients from individual heat transfer coefficients or from energy material/balance findings 
7. Analyze phase change state, filmand dropwise condensation, nucleate and film boiling of liquids (evaporation). 
8. Analyze heat exchangers. 
9. Apply fundamental heat transfer principles to perform heat exchanger design and performance calculations.

INTENDED LEARNING OUTCOMES

1.  Recall the principal terminology, concepts and theories of heat transfer by conduction, convection and radiation
2. Translate simple problems involving heat exchangers components and systems into a form which can be solved using standard mathematical methods. 
3. Solve transient problems 

• Skills and other attributes: On successfully completing this course unit, students will be able to:
•  Intellectual skills
