Three-Dimensional CFD Model Development and Validation for Once-Through Steam Generator (OTSG): Coupling Combustion, Heat Transfer and Steam Generation

The current research studies the coupled combustion inside furnace and steam generation radiant convection tubes through a typical Once-Through Steam Generator (OTSG). A 3-D CFD model coupling two-phase flow was developed to entire system of OTSG. Once simulation converged, results were compared field data showing convincing agreement. analysis provides detailed behavior chamber stack, as well process in convective sections. flame shape orientation, velocity, species, temperature distribution at various parts furnace, pipes investigated using
