The large meshes generally required 32 to 96M words of main memory. It also allowed the debugging process to be completed on the smallest meshes. Because of the multi-layered approach, run times that had required 150 CPU hours in the past were completed in under 30 CPU hours. The results provide insight to the ramifications of a given design on submarine flowfields. Important information includes potential noise sources resulting from recirculation zones and nonuniform flow at the propulsor inlet.
Appendages potentially affect submarine maneuverability, hydrodynamic ,serformance, and signatures.
Computational analysis can provide a cost-effective tool for appendage design, leading to higher performance without higher detectability and thus, broader mission capability. All rights reserved.
