Abstract:

Hot isostatic pressing (HIP) is a crucial process to densify and enhance the material properties of components in aerospace, energy, medical and additive manufacturing. In recent years people start to focus on understanding the shrinkage and deviation of parts in the HIP process by calculating the temperature-pressure behaviour on parts during heating, steady-state and cooling.This work shows 3D computational fluid dynamics (CFD) as a powerful tool to obtain an increased and complete understanding of the details in thermal gradients and gas flow inside the HIP furnace. An innovative full-scale 3D CFD simulation method of a HIP furnace in operation will be presented. This innovative method allows detailed full-scale 3D calculation of all the important processes including the gas flowing, pressing, thermal radiation and conjugate heat transfer in solids and fluids so that the HIP process can be best simulated in reality without unnecessary error-bringing simplifications.
