A heat slab with an initial uniform temperature of is considered. It has a length and wide which is
instantly limited from left and bottom to a constant heat flux of The top edge is insulated while the right
edge is at constant temperature of
Assume that the slab does not have any heat transfer with the environment. Derive the unsteadystate
model of temperature distribution for this slab using the information given starting with the shell
balance
State the initial and boundary conditions correctly
Remember that this model would have two spatial and one accumulation term
If you make a mistake during modelling, the rest of calculations will not be considered in your evaluation
Consider the steadystate,
Derive the equivalent algebraic equation of the model.
If i and are defined from zero up to and respectively, specify and
Use direct method and create the matrix of the equations. Then solve the equations in Excel.
Use Liebermann method with relaxation factor of and continue the iterations up to times, and
calculate the last values of for each node. Report the last temperature values of the nodes.
