Unexpected and costly thermally induced failures have been reported at power as well as process plants. The failures are caused by complex thermal-hydraulic mechanisms classified as Thermal Stratification, Cycling and Striping (TASCS). These mechanisms can cause fatigue cracking, pipe deformations, pipe support damage, and additionally lead to anticipated equipment failure. Three-dimensional, transient CFD simulations are necessary in order to predict the nature of these failures. The analyzed phenomena are diverse and complicated because of the wide variety of thermal-hydraulic and...
The presentation describes the evolution of features made available in recent releases and new capabilities that will be available within the forthcoming v4.22 release and their application to in-cylinder engine calculations. These include: Further development of combustion models including dual-fuel combustion such as diesel-natural gas; Support for 3rd party chemistry within the advanced ECFM and PVM-MF combustion models; Crank-angle resolved Conjugate Heat Transfer (CHT) analysis and automated meshing using STAR-CCM+.
Multiphase and reacting flow simulation capabilities of STAR-CCM+ is increasing with every release. This makes it possible to solve advanced level problems in the chemical processing industry. Some of the largest chemical companies around the world use STAR-CCM+ for addressing challenging day to day problems. A few pertinent enhancements from this year will be reviewed. Then some recent validation and case studies in gas-liquid flow, fixed bed reactor modeling and heater design optimization will be presented.
This presentation will provide recent examples of our work for all three major components of the gas turbine, compressor, combustor, turbine, i.e. we will present examples on the following sub-topics: Multi-stage flow simulation of axial compressor (Heavy Duty GT) and coupling to our ACF compressor design tool DLN combustor analysis (industrial GT) Turbine Cooling: Upgrade of E-Class Heavy Duty GT Advanced Film Cooling Technology: 1st Rotor Blade of industrial GT
An overview of the challenges of FSI will be presented along with the capabilities available in STAR-CCM+ to meet those challenges. The topics will include: a) Data mapping techniques b) Protocols and formats for exchanging data between CFD and CSM codes c) Coupling methods for stability and accuracy d) Techniques for dynamic fluid mesh evolution e) Validation of FSI results A technical overview under each of these topics will be provided. A range of examples which demonstrate the STAR-CCM+ FSI capabilities and validate the accuracy will be shown. The examples span analytical and experimental...
Recently, electric motor is required high efficiency and smaller. In order to satisfy high reliability, importance of thermal management for electric motor is rising. In this session, we introduce thermal management of electric motor by STAR-CCM+, SPEED and JMAG.* *JMAG is a registered trademark owned by JSOL Corporation.
Two new Virtual Product Development (VPD) series tools will be introduced: 1. OpenRoad is used to perform aerodynamic and thermal management assessments on ground vehicles. 2. EPH (Estimated Hull Performance) can be used to assess hull hydrodynamic performance in calm water.
CD-adapco not only provides the world's most comprehensive engineering simulation inside a single integrated package with STAR-CCM+ and STAR-CD, we also pride ourselves on the outstanding quality of our technical support. Every customer has access to a Dedicated Support Engineer, who is specifically tasked with understanding your application, and anticipating solutions to your problems, before they even happen.

In this presentation the overset grids methodology implemented in STAR-CCM+ will be first described, followed by the explanation of how to access this feature through the user interface. Next, the advantages of overset grids compared to alternative approaches when performing parametric studies or simulating motion of bodies relative to each other are discussed. Several examples of the use of overset grids for both steady-state and transient flows around static or moving bodies will be presented to illustrate the various features of overset grids. Finally, future developments of this...
LNG sloshing
Ships are being designed with increasingly larger insulated holding tanks to allow for a growing capacity in the marine industry and now more than ever, sloshing and structural integrity of these bigger tanks pose a significant technical challenge to the Marine Industry. Shown is LNG sloshing in a tank.
