Abstract
Computational Fluid Dynamics (CFD) analyses were performed for an armored tank engine compartment cooling flow. Large hybrid unstructured meshes (2.5–3.0×106 cells) were constructed using the ICEM-CFD grid generator. The flow and convective heat transfer field were computed using an in-house CFD code, NPHASE. The commercial software package, RADTHERM was utilized to incorporate radiation heat transfer within the simulations.
Two steady operating conditions and one engine-off cool-down transient were analyzed. Specifically, the conditions analyzed were open throttle (hereafter OT), Tac Idle (TI) and engine off soakback (SB). OT and TI were run with and without convection heat transfer employed in the radiation assessments to provide best-estimate and conservative peak temperature predictions respectively. SB was run transiently using fixed heat transfer coefficients obtained from NPHASE analysis.
Results are presented for the simulations performed, with emphasis placed on peak temperatures of several design critical elements.
