Introduction Flashcards
1
Q
What is heat transfer?
A
Thermal energy transfer in transit due to a spatial temperature difference
2
Q
What is conduction?
A
Transfer of energy from more to less energetic particle due to particle interactions
3
Q
How is heat transfer quantified?
A
Rate equations: Fourier Law
4
Q
What is convection?
A
conduction + advection
energy transfer due to random molecular motion (conduction or heat diffusion) + energy is also transferred by the bulk, or macroscopic, motion of the fluid (advection)
5
Q
What is Radiation?
A
Transfer of heat using electromagnetic waves.
6
Q
What is the surface emmisive power?
A
The rate at which energy is released per unit area
7
Q
What is a black body?
A
Ideal radiator
