CFD Studies

Zeta-pdm provides a full consultancy service, helping to identify and rectify problems, optimise efficiency and increase throughput. Zeta-pdm uses process visualisation methods to provide an accurate representation of the expected distributions of each flow component during the seperation processes. These methods rely on in-house Computational Fluid Dynamics (CFD) capabilities.

Process calculations aim to provide information on the operating conditions inside a separator vessel but they cannot show the actual fluid flow field associated with the process in any detail.

Zeta-pdm utilise the latest CFD techniques to troubleshoot existing designs and to enhance new build designs. With CFD we are able to create model geometry, which is highly representative of the separator vessel. The model is then split to form a computational grid consisting of literally millions of individual cells. The equations of fluid flow are solved at each separate and discrete cell point and then combined to provide a solution for the overall flow field. Zeta-pdm have the knowledge, resources and equipment to push the accuracy level as close to perfection as is humanly possible.
