The toolset will be comprised of a variety of components related to two-phase flow systems with user interfaces to parameterize the component models and a variety of supporting tools for operating the models and analyzing results. The software toolset will then be verified using established physics and mathematics and validated against hardware data. Software documentation will be generated and example models addressing the specific modeling needs of the Navy will be created as part of the toolset delivery. Benefits: High power low duty cycle heat loads are becoming more prevalent in modern warfare technologies necessitating advanced cooling architectures and control strategies. Two-phase cooling has been identified as a critical component of these candidate architectures due to the large heat transfer capacity per unit volume and mass. Modeling and simulation offers a cost effective means for analyzing multiple architectures and control strategies, but the complexity of the two-phase fluid flow and heat transfer physics leads to difficulty in dynamic modeling. The proposed toolset intends to address this complexity in the creation of dynamic, time-domain component models with the relevant physics necessary to capture the component dynamics. User interfaces will be established allowing users to parameterize the component models to match their design needs. The successful completion of such a toolset will provide long term return on investment to the Navy and other industry participants as two-phase flow cooling technologies become more prevalent in advanced warfare concepts. The initial investment in a software toolset continues to provide benefit well after the program completion as the generic component models are readily parameterized to meet a user�s specific application.
