Thermo-Physical Properties

Question 1

List the thermo-physical properties that influence dynamic conduction.

Answer 1

1. Conductivity (W/mK)
2. density (kg/m3)
3. specific heat (J/kgK)

Question 2

What parameters do the thermo-physical properties depend on?

Answer 2

1. Temperature
2. Moisture content
3. internal structure

Question 3

What determines how fast a heat flux fluctuation is transmitted?

Answer 3

Thermal Diffusivity. Higher the diffusivity, faster the transmission.

Question 4

What determines how readily a material absorbs a surface heat flux?

Answer 4

Thermal effusivity. Higher the effusivity, faster the absorption.
