TEMPEST – A Computer Code for Three-Dimensional Analysis of Transit Fluid Dynamics

TEMPEST is a family of codes with two primary versions:

N-Version, which is available to the public, can be used to analyze a broad range of coupled fluid dynamic and heat transfer systems in complex three-dimensional geometries.

T-Version, which is developmental and not yet available to the public, is an important tool for investigators at PNNL, who use this version of TEMPEST in sponsored research for clients. It has all the capabilities of the N-version; moreover, it can also be used to solve problems with AC/DC electric fields and Joule heating models, compressible flows, marine hydrodynamics with free wave surfaces, non-Newtonian rheology models, and multiconstituent transport in curvilinear

Codes for numerical prediction of complex three dimensional thermal-hydraulic processes are now standard tools for design and process engineers. The main obstacle to full utilization of numerical simulation in engineering applications are the cost of developing robust numerical solution methods for detailed theoretical and empirical models and the limitations on execution time for large and complex problems on serial machines. The increasing availibility of affordable massively parallel processors, networks of workstations, symmetric multiprocessors, and moderate size shared memory computers is making it possible to perform simulations of larger and more complex problems.

To this end a parallel version of TEMPEST was developed by Don Trent and George Fann.
