RSICC CODE PACKAGE PSR-559

1.         NAME AND TITLE

TEMPEST-BNW:    Transient 3-D Thermohydraulics for FBR.

AUXILARY CODES: 

SEQUEL and MANPLOT for plotting output.

The MANPLOT source, as supplied, is designed for a DEC VAX11/780.

2.         CONTRIBUTORS

Pacific Northwest Laboratory, Richland, Washington, through the NEA Data Bank, Issy-les-Moulineaux, France.

3.         CODING LANGUAGE AND COMPUTER

Fortran (P00559C760000).

4.         NATURE OF PROBLEM SOLVED

The finite-difference approach for the fluid- flow solution is based on a semi-implicit procedure whereby the momentum equations are solved explicitly, and the continuity/pressure solution is obtained implicitly. The energy equation is solved with a fully implicit method, and a direct steady-state option is available for heat transfer only problems.

5.         METHOD OF SOLUTION

TEMPEST-BNW is a transient, three-dimensional, hydrothermal program that is designed to analyze a range of coupled fluid dynamic and heat transfer systems of particular interest to the Fast Breeder Reactor (FBR) thermal- hydraulic design community. The full three-dimensional, time- dependent equations of motion, continuity, and heat transport are solved for either laminar or turbulent fluid flow, including heat diffusion and generation in both solid and liquid materials. The equations governing mass, momentum, and energy conservation for incompressible flows and small density variations (Boussinesq approximation) are solved using finite-difference techniques. Analyses may be conducted in either cylindrical or Cartesian coordinate systems. Turbulence is treated using a two-equation model.

Two auxiliary plotting programs, SEQUEL and MANPLOT, for use with TEMPEST-BNW output are included. SEQUEL may be operated in batch or interactive mode; it generates data required for vector plots, contour plots of scalar quantities, line plots, grid and boundary plots, and time-history plots. MANPLOT reads the SEQUEL-generated data and creates the hard copy plots.

TEMPEST-BNW can be a valuable hydrothermal design analysis tool in areas outside the intended FBR thermal-hydraulic design community.

6.         RESTRICTIONS OR LIMITATIONS

Limitations of the current release, identified as TEMPEST Version L, Mod 3, are as follows: incompressible flow only; computational cell structure must be in rows/columns/tiers; Cartesian or cylindrical coordinates only; hydrodynamic solution is explicit in time - no direct solution for steady-state, pressure boundary conditions are not available; and curved boundaries (except circular) must be stair-stepped.

7.         TYPICAL RUNNING TIME

Not stated.

8.         COMPUTER HARDWARE REQUIREMENTS

MANPLOT uses the proprietary CalComp graphics software, which is not included. The MANPLOT source, as supplied, is designed for a DEC VAX11/780.

9.         COMPUTER SOFTWARE REQUIREMENTS

A Fortran compiler is required.
