General Topics

1/14/2020 Syllabus 5

Radiative Heat Transfer

• This course will examine thermal radiative heat transfer, that occurs when the temperature of a substance (solid, liquid, or gas) is > 0 K.

• Unlike nuclear radiation which is a result of radioactive decay, i.e., the breakdown of an unstable nucleus of a large atom to form a more stable one.

• There are three types of nuclear decay:

Alpha - an unstable nucleus emits an alpha particle which is composed of two protons and two neutrons; i.e., it is effectively a helium nucleus.

Beta - an unstable nucleus emits an electron (a beta particle),

Gamma - an unstable nucleus emits high energy electro-magnetic radiation called gamma rays.

Course Overview

Radiative Heat Transfer

• We will begin with an introduction to the physics of thermal energy transfer by radiative processes and cover;

- the physical properties of radiative heat transfer, - the influence of various surfaces materials and

conditions, as well as other participating media.

• This course will also serve future courses which focus on issues related to:

- Aviation Fire and Explosion Dynamics- Thermal Management in Satellites and other Space based vehicles,

as well as combustion and thermal transport applications.

• This dual level course is presented in a way to enable both undergraduate and graduates to master its material.

Weather Policy

• In the event of snow or bad weather, I recommend each student check the UC web site before attempting to come to class.

• If the University is open, I will attempt to have class. If the University is closed for part of class, the entire class is cancelled.

• If for some reason I cannot make it in due to severe weather, I will try to post an email to all students in the class.

• No student will be penalized for not attending class due to bad weather.

1/14/2020 Syllabus 9

• Attend each class.

• Print out abridged lecture notes.

• Read and fill in missing information in abridged notes.

• Complete assignments in a timely manner.

• Interact in class through questions and discussions.

• Contribute to the classroom discussion.

• Seek out additional study material from external sources (library, etc.).

• Begin to formulate questions regarding the term project (if available) in a timely manner.

Expectations of Students

1/14/2020 Syllabus 10

a. Grade Calculation = Class exam (15%) + Final project (85%).

b. Inappropriate language will not be accepted in the classroom, and individuals displaying such behavior will be asked to leave the lecture.

c. Due to the distraction caused by electronic communications during class, all electronic communication devices must be placed in silent mode and stored. If you are found using such devices in class you will be warned or asked to leave the room. NO TEXTING!!!

d. All electronic communication devices must be turned off during exams. If a device is found activated during an exam a 20% grade penalty will be imposed. No Exceptions!!!
