Numerical calculation of heat transfer in cylindrical coordinates using finite-difference method in evaluating temperature of different points of radiopharmaceutical vials

Choosing the type of vial of radiopharmaceuticals, the materials of canned goods and food, as well as the thickness of their walls, plays an important role in the transportation of companies' products. Regularly, the optimal design of the type of food wall has a significant effect on the shelf life of the products inside it, which can be more resistant to heat. Especially, carrying vials of radiopharmaceuticals, which plays a vital role in medical centers and hospitals in hot cities around the world. Therefore, in this research, different points of a container containing biological material are analyzed numerically to estimate the heat transfer and the temperature distribution in it.
