Fig 4.10 Variation <strong>of</strong> average temperature with dimensionless time, for B=1 to 5 for a slab<br />
Fig (4.11) shows the comparison <strong>of</strong> present <strong>analysis</strong> with the other available results. These<br />
<strong>in</strong>clude classified lumped system <strong>analysis</strong> and exact solution by E.J. Correa and R.M. Cotta [4]<br />
<strong>of</strong> a slab. It is observed that the present prediction shows a better result compared to CLSA. The<br />
present prediction agrees well with the exact solution <strong>of</strong> E.J. Correa and R.M. Cotta [4] at higher<br />
time. However at shorter time, the present <strong>analysis</strong> under predicts the temperature <strong>in</strong> solid<br />
compared to the exact solution. This may be due to the consideration <strong>of</strong> lumped model for the<br />
<strong>analysis</strong>.
