Researchers at NASA’s Johnson Space Center have developed and enhanced simulation software that designs and analyzes complex thermal/fluid systems. The software innovation is a system for computational simulation of interacting thermal and fluid effects in arbitrary flow networks. It is used to design and analyze aerospace systems, such as thermal control and propulsion, and is a combination of two subprograms. Systems Improved Numerical Differencing Analyzer (SINDA) solves lumped-parameter representations of physical problems governed by diffusion-type equations. The Fluid Integrator (FLUINT) program is an advanced one-dimensional fluid-analysis program that solves equations of arbitrary fluid-flow networks. Working fluids that can be modeled in SINDA/FLUINT include single-phase vapors, single-phase liquids, and two-phase fluids. Originally designed for aerospace applications, the technology can be used in a wide range of diverse industries. The system has simulated nuclear reactors, windshield wipers, even human windpipes. This software may be released for U.S. Government purposes only.
This technology is being made available through JSC’s Technology Transfer and Commercialization Office, which seeks to transfer technology into and out of NASA to benefit the space program and U.S. industry. NASA invites companies to consider licensing this technology for commercial applications.
