New capabilities in modeling multiphase flows using the Eulerian Multiphase (EMP) model are demonstrated by examples. These new capabilities include granular model for multi-size particle flows, RSM for turbulent multiphase flows, multi-component boiling model for evaporation of chemical species and the Adaptive-MUSIG (A-MUSIG) population balance model for poly-dispersed flows.
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.

The most common simulation for electronics products involves predicting the system temperature under the chosen cooling methodology. This presentation will overview the primary best practices for thermal simulation of electronics models. Specific techniques in STAR-CCM+ will be addressed covering the entire CAD-to-results process including geometry preparation, meshing, physics setup, conditions, and solution settings on models with hundreds of components. Both forced and natural cooling simulations involving conduction, convection, and radiation will be examined in the detailed tips and...
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.
