  • Flame Modeling Provides Matchless Results

    A computer simulation helps solve a refinery combustion problem. Finding ways to limit NOx from fired heaters, especially under stringent environmental regulations, has become a major concern for the petroleum refining industry. Complying with new stricter regulations, a Texas refinery upgraded the burners in one of its large cylindrical furnaces.

  • The Synergy of Simulation, Experimentation and Technical Support Activities in a Research Consortium

    For the business of designing process heat exchangers, computational fluid dynamics (CFD) tools are still not practical for everyday use. However, in a research consortium such as HTRI, integrating advanced analysis tools like CFD with industrial-sized experimentation and then applying them to real-world technical problems provides a significant synergistic benefit to the consortium members.
