Sara Duclos, Kayla Eckley, Joseph McGrath, Department of Chemical Engineering, University of New Hampshire. Introduction. Objectives. Methods. Results. Design Problem. References. Condensers are involved within systems in order to cool an environment with the evaporation and condensation of a fluid. Fins and Extended Surfaces. 1. Chapter 3c : One-dimensional, Steady state conduction (with thermal energy generation) (Section 3.5 – Textbook). 2. 3.1 Implications of energy generation. Involve a local source of thermal energy due to conversion from another form of energy in a conducting medium.. . conduction. c. onvection. radiation. Energy can be transferred from one system to another (or from a system to its environment) in different ways: . Thermally. , when a warmer object is in contact with a cooler . ON HEAT TRANSFER COEFFICIENT (h) OF FLUIDS IN CONTACT WITH . SOLIDS OF DIFFERENT TEMPERATURE IN NATURAL CONVECTIVE HEAT TRANSFER. (for Bonus Quiz No. 6 of ME 130 Course on Applied Engineering Analysis). LO3.1: Lesson . 1. : . . Type of Heat Exchangers (. Recuperators. ). Aim. LO3: To be able to Evaluate Heat Transfer Equipment.. Learning Outcomes. At the end of this session the students will be able to…. How does heat energy get from the Sun to the Earth?. There are no particles between the Sun and the Earth so it CANNOT travel by conduction or by convection. . ?. RADIATION. How can we relate our new understanding to the greenhouse effect?. “L JJAM” aka “Dream Team” aka Team 3. CHBE446 02/02/18. HOT HOT HOT! . Background Theory. Conduction. Convection. Heat Exchangers. Photo Cred: Meghan. Heat Transfer. The physical process in which thermal energy is transferred from one object to another as a result of a temperature difference. Extended Metaphor An extended metaphor is a  metaphor  that unfolds across multiple lines or even paragraphs of a text, making use of multiple interrelated metaphors within an overarching one. Definition of Extended Metaphor Do now activity: . Describe the difference between the processes of conduction and convection.. GOOD PROGRESS:. Describe some sources of infrared radiation.
