2. MEASUREMENT OF THERMAL CONDUCTIVITY USING THERMAL COMPARATOR

3. AIM To measure the thermal conductivity of composite materials in unsteady state condition using thermal comparator.

4. 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.

5. 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.

6. COMPONENTS USED. 1. Wood. 2. Phosphor-Bronze Balls (2 nos). 3
COMPONENTS USED 1. Wood 2. Phosphor-Bronze Balls (2 nos) 3. Microwave oven 4. Thermocouples 5. Potentiometer

8. 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

9. METHODOLOGY. First the whole setup is heated in oven
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.

10. 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
