FORT WORTH, TX (19 November 2013)—Pointwise is hosting a free webinar entitled Estimating the Power Requirement of a Rushton Turbine Using Pointwise and OpenFOAM® at 3 p.m. CST (GMT-6) on 11 December. The 30-minute webinar will address meshing and simulation challenges related to the highly three-dimensional flows associated with efficient mixing in impeller-stirred tanks and will include a question-and-answer session. To register, go to www.pointwise.com/webinar.

The webinar will demonstrate how to use Pointwise to generate high-quality unstructured meshes suitable for steady-state moving reference frame calculations, using a generic, baffled tank stirred by a Rushton turbine. The boundary conditions and zones necessary for OpenFOAM will be demonstrated using Pointwise’s recently-updated native interface. Also shown will be how to prepare an Open FOAM case for a moving reference frame calculation and compute the power necessary to drive the Ruston turbine in a single-phase flow.

Presented by Travis Carrigan and Dr. Darrin Stephens, the webinar will demonstrate how to

- Resolve thin geometric features using diagonalized quad grids

- Quickly create point-matched periodic surface meshes to improve interpolation accuracy

- Save time by creating Sets and Zones for OpenFOAM directly within Pointwise

- Easily setup OpenFOAM cases for moving reference frame calculations

- Compute torque/power requirements using OpenFOAM functions

Mr. Carrigan joined Pointwise as a senior engineer after completing his M.S. in aerospace engineering at The University of Texas at Arlington in May 2011, where his graduate research involved aerodynamic design optimization. He interned at Pointwise beginning May 2008, producing demonstration and application videos and working in technical support, doing grid projects and quality assurance testing. During a prior internship at Vought Aircraft Industries, Mr. Carrigan worked as a quality engineer on the Boeing 787 Dreamliner Program. As a senior engineer at Pointwise, Mr. Carrigan works with clients to strengthen their computational fluid dynamics (CFD) processes by developing interactive and automated meshing solutions.

Dr. Stephens has an extensive background in modeling a range of complex reacting multi-phase flows and led the development of CFD models for a number of industrial unit processes allowing re-design and optimization, improving throughput and efficiencies. He is the managing director and principle research engineer at Applied CCM Pty Ltd., a company providing development, technical support and training for the open source CFD software OpenFOAM. Applied CCM has been a distributor of Pointwise since 2011. Along with development, training and support services, the company offers a fast transient, improved compressible and incompressible and robust surface-based adjoint solvers for OpenFOAM.

Dr. Stephens’ professional interests include optimization and optimization algorithms, population balance modeling, coupled solvers and the development of next-generation hybrid and multi-physics models. He earned his mechanical engineering B.Eng. and Ph.D. degrees from James Cook University in Townsville, Australia.
