Project Description:

A Seal is considered to be one of the most important components of a variety of rotating machinery used in chemical, petrochemical and process industry in Louisiana and the nation. If a seal fails to perform its intended task, there will be severe environmental impact and forced shut down of a plant. As a part of our research, we are concentrating on the prediction of the flow and heat transfer characteristics of mechanical seals. This research activity is in conjugation with experimental work on a new generation of seals, currently underway in the LSU Center for Rotating Machinery. The problem involves solving Navier-Stokes equations which are coupled with the energy equation. The solution requires significant computational effort. Thus far, we have obtained some promising numerical results for the following.

  • The flow field around the mechanical seals (Fig1)
  • The temperature distribution of the whole domain including the mechanical seals and the fluid around (Fig2)
  • The Nusselt Numbers and heat transfer coefficients around the seal rings.

Additional work is ongoing to verify the results of the simulations.

:Main objectives:

1. Obtain a 3D numerical analysis of heat transfer of the mechanical seals.
2. To apply the analysis to improve the design of the seal mating ring.
