ELM, from NASA Lewis Research Center, is a simple computational tool for
modeling the steady-state thermal-hydraulics of propellant flow through
fuel element coolant channels in nuclear thermal rockets. Written for the
nuclear propulsion project of the Space Exploration Initiative, ELM
evaluates the various heat transfer coefficient and friction factor
correlations available for turbulent pipe flow with heat addition.

ELM, LEW-15423, is a machine independent program written in FORTRAN 77. It
has been successfully compiled on an IBM PC compatible running MS-DOS
using Lahey FORTRAN 77, a DEC VAX series computer running VMS, and a Sun4
series computer running SunOS UNIX. ELM requires 565K of RAM under SunOS
4.1, 360K of RAM under VM and 406K of RAM under MS-DOS. No executable is
provided on the distribution media. The standard distribution medium for
ELM is one 5.25 inch 360K MS-DOS format diskette. Program $480;
documentation $16.
