MEASUREMENT OF THERMAL
CONDUCTIVITY USING THERMAL
COMPARATOR
AIM
To measure the thermal conductivity of
composite materials in unsteady state condition
using thermal comparator.
SCOPE OF THE PROJECT
* Now a days, the thermal conductivity
value for materials like Iron, Aluminium,
Copper, etc., can be taken from the data book.
* But for composite materials there is no
such data.
* This project helps us to find the value of
thermal conductivity for composite materials
also.
OBJECTIVES
* To calibrate the known thermal
conductivity of the materials.
* To find the thermal conductivity for
composite materials.
* To analysis the value of thermal
conductivity using ANSYS.
COMPONENTS USED
1. Wood
2. Phosphor-Bronze Balls (2 nos)
3. Microwave oven
4. Thermocouples
5. Potentiometer
FORMULA
Q= -kA dT/dx
Where
A – Area in m2
dT/dx –Temperature gradient in k/m
k –Thermal conductivity in W/mK
Q –Heat transfer in W
METHODOLOGY
* First the whole setup is heated in oven.
* Then the setup is left and placed on the
testing samples.
* The thermal e.m.f for every 10 seconds
will be noted.
* The two graph is drawn using this value.
* By comparing the graphs the thermal
conductivity is calculated.
TIMELINE
STAGE 1:Literature survey and materials
collection in january
STAGE 2:To fabricate the thermal comparator in
february
STAGE 3:To analysis the thermal conductivity
value in ANSYS in march
