This paper reviews the mathematical modelling associated with the plunger cooling tube system in the NNPB process and highlights the results achieved and some of the problems encountered. Preliminary results obtained using a computational fluid dynamics (CFD) software package show that there are areas within the airflow passage along the cooling tube systems that experience recirculation and choking. Further work is being undertaken by the authors using the ANSYS CFC software package to establish the appropriate parameters for optimum plunger cooling to overcome plunger failure.
