Pulmo: An Underwater Blast Lung Computational Model

Karagozian and Case, Inc. (K&C) and Johns Hopkins University Applied Physics Laboratory (JHU-APL) propose to extend a Phase I prototype of a computational model and end-user software to model of the human lung as it responds to underwater blast insults. The computational model is fully resolved in the both space and time, exhibits high-fidelity material models and computational domains for the air, water, and the lung tissues, can model or accept input UNDEX pressure time-histories (including those obtained from experiment pressure records), and has physical parameters that account for the essential physics and physiological variables. In this proposal, K&C and JHU-APL propose to extend the computational model to an complete upper torso model that incorporates other anatomical structures essential to model the physics and physiological injury phenomena at sizes accurate to a 50th percentile male, validate it with UNDEX experiments, and enhance the end-user software.
