[The book name for the two homeworks is a Nuclear Heat Transport]

Homework- 6

Due date:

The 3D, unsteady thermal heat conduction equation is givenby:

ρC

where,

ρ is the fuel density,

C is the specific heat of the fuel,

K is the thermal conductivity of the fuel.

K is defined from the Fourier law:

Where q is the rate of thermal energy transfer,and A is the area normal to the direction \"n\" ofheat transfer. For constant K, the equation reads:

Divide both sides by K, and define the thermal diffusivityα

α   =    

The equation becomes:

Q) For the metric system of units, what is theunit of the thermal diffusivity α ?
