| Outline of Final Research Achievements |
To investigate the heat transfer characteristics of sand stone due to cooling and heating process, cylinder of 50mm diameter and sphere of 50mm and 100mm diameter were used as the samples. Two types of boundary conditions had been used for the derivation of exact solutions of the governing equations. They were Dirichlet boundary (DB) and heat transfer boundary (HTB) conditions. Hence, comparison had been made on these two boundary conditions to identify their suitability on heat transfer characteristics. The results show that the exact solutions derived using HTB has been fitted better than DB for both cooling and heating phenomenon in cylinders as well as in spheres.
