FORT WORTH, TX (22 August 2013) – Combustion Research and Flow Technology (CRAFT Tech), CEI and Pointwise will present a joint, 30-minute webinar at 10 a.m. CDT (-5 GMT) on 12 September on how to utilize the best CAE tools to investigate and understand the complex cavitation phenomena occurring in high energy water injection pumps. The complex geometry and physics make it challenging to predict the unsteady interactions between the various components of the pump and the potential for cavitation in the impeller.
The webinar will be presented by Jeremy Shipman, research scientist at CRAFT Tech; Kevin Colburn, sales manager at CEI, and Travis Carrigan, senior engineer at Pointwise.

The team at CRAFT Tech utilizes Pointwise for preprocessing and relies on its ability to easily manage and organize complex assemblies so they may focus on meshing a single component or multiple components at any time. This allows engineers to rapidly generate multiple blocks resulting in high quality hybrid grid assemblies while maintaining the connectivity between adjacent components to improve interpolation and solution accuracy.
CRAFT Tech's CRUNCH CFD solver is utilized to resolve the unsteady interactions within the pump and the physics involved with predicting cavitation. CRUNCH CFD contains cavitation models as well as the ability to treat the thermodynamic effects of vaporizing fluids. Both single- and two-phase unsteady analyses of the pump system are performed to understand the potential for impeller cavitation and predict the far-field acoustic properties of the pump.
Finally, EnSight is used to help extract, visualize, and communicate the results of the solution to help understand the performance and ensure a proper design of the pump. EnSight's capability to illustrate the implicit motion of the impeller, along with dynamic and flexible post processing environment allows the engineers to quickly and easily extract key information from a complex result.
The webinar will demonstrate how to
Mr. Shipman joined CRAFT Tech in 1998 after completing his M.S. in Mechanical Engineering from the George Washington University. Since joining CRAFT Tech, he has been involved in the numerical simulation of a broad range of applications, including high altitude continuum/rarified flows, chemically reacting and particle laden flows, cryogenic liquid turbopumps and feed systems, and flight simulation models for aircraft launch and recovery from Naval ships. He has many years experience utilizing pre and post processing tools from Pointwise and CEI with CRAFT Tech's flow solvers in the CFD analysis process.
Mr. Colburn joined CEI in 2007 after working for 14 years in automotive, combustion and aerospace fields as a CFD engineer. His background is as a CFD user utilizing a wide variety of tools and techniques within real world design cycles. Mr. Colburn had seven years' experience using EnSight as a user before joining CEI. He received his B.S. from Rensselaer Polytechnic University in 1995.
Mr. Carrigan joined Pointwise as a senior engineer after completing his M.S. in aerospace engineering at The University of Texas at Arlington in 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 CFD processes by developing interactive and automated meshing solutions.
