3D Conjugate Heat Transfer Analysis of the Next Generation: Inner Reflector Plug for the Spallation Neutron Sourc
The Spallation Neutron Source (SNS) is an accelerator-based neutron source at Oak Ridge National Laboratory (ORNL). The SNS facility provides the most intense pulsed neutron beams in the world for scientific research and industrial development. The liquid mercury target, moderators and beryllium reflectors are contained inside the inner reflector plug. The main objectives of the redesign of the inner reflector plug are simplifying its disposal and increasing its neutronic performance. The inner reflector plug is actively cooled by flowing heavy and light water through a maze of channels...
Experimental Validation of STAR-CCM+ for Liquid Container Slosh Dynamics
The NASA Launch Services Program has funded several propellant slosh related projects over the years with the goal of obtaining experimental data to anchor CFD predictions. STAR-CCM+ is used to create a CFD model of water sloshing in an 8” diameter spherical tank. The predictions from this CFD slosh model are compared to experimental data to validate the results. The data compared include slosh natural frequency, damping rate and free surface topology. These important validations allow us to increase our confidence in STAR-CCM+ for use on NASA missions.

Numerical Validation of the Noise Characteristics of the Radial Fans with Forward Curved Blades
This presentation investigates the noise characteristics of radial fans with forward curved blades by performing CFD simulations with the emphasis on employing different turbulence models (RANS/URANS, DES, LES) and unstructured grids. The noise radiated from the fan is calculated with the aeroacoustic models provided by STAR-CCM+ (e.g. FW-H) and correlated with the results obtained from the hybrid approach (using ACTRAN) as well as the experimental results obtained from duct method according to DIN EN ISO 5136. The predicted noise spectra obtained from the simulations are in good agreement...
Class 8 Tractor Trailer Aerodynamics
Evaluating aerodynamic drag of class 8 trucks is critical for improving fuel economy, meeting EPA targets and maintaining a competitive edge in the industry. For a standard tractor trailer configuration, aerodynamic drag is responsible for approximately 30% of total fuel consumption. Reducing drag by 3% would improve fuel economy by 1%, which demonstrates the need for accurate methods to predict aerodynamic drag. Depending on available resources, truck companies may use one or more tools to evaluate drag, including wind tunnels and CFD software. This presentation focuses on the application of...
High Productivity CFD Workflows with STAR-CCM+ & FieldView: Real-World Success with HPC & CFD
Zipp Speed Weaponry used CFD simulation results, wind tunnel testing and their own creativity to rapidly develop a state-of-the-art product that succeeded in an already crowded bicycle racing wheel market. Their Firecrest wheels were a technological breakthrough that delivered 100% category revenue growth and the addition of over 120 new manufacturing jobs in Indiana in just two years, confirming their place as the established leader in this hotly contested market. With the help of Intelligent Light and CD-adapco, the company is working to rapidly develop a well-engineered, highly automated...

Transient Radial Blower Simulation as Part of the Development Process
Behr GmbH & Co. KG is a leading supplier in the automotive industry in the field of thermal management. Radial blowers are a central component of the air-conditioning system of a passenger compartment. The target for the development of a radial blower is to increase the efficiency of the blower while reducing the noise level. This enables the provision of adequate air flow in all operating points. For supporting the development of radial blowers a CFD method based on transient DES simulations with STAR-CCM+ was developed. The development of the method was accompanied with various...
Virtual Testing for Automotive Components & its Integration into the OEM´s Product Creation Process
InDesA operates a suite of virtual test benches for automotive auxiliary components, such as fans, pumps, compressors and heat exchangers. The objective is to speed up design iterations by verifying CAD designs directly by virtual performance testing and without the need of building prototype components for physical bench testing. As automotive components from suppliers are integrated into larger systems this is done within the OEM’s development process and software environment. Consequently the component’s performance data must be adapted to suit the requirements of other simulation...
