STAR-CCM+ Computational Fluid Dynamics simulation software is a powerful tool with which numerical values of the velocity and temperature can be indicated in nearly every point of the flow. But after every STAR-CCM+ simulation the following question remains: Does the numerical results correspond to the values in the reality? One possibility is to measure the velocity at different points of the flow using a prototype and a test bench. This option is not developed here. Another possibility is to compare analytical results with the STAR-CCM+ simulation. For the first time, the analytical results...
KTH Royal Institute of Technology (KTH) is one of European’s key centers of innovation and intellectual talent for almost two centuries. Recognized as Sweden’s most prestigious technical university, KTH is also the country’s oldest and largest. Computerized simulation technique was recognized as a fundamental component of the higher-education sector at KTH as early as the fifties. Although the utilization of these tools in research is now considered to be standard, the educational aspects are not. In this field, the method of instruction followed by practice is considered to be a superior...

In this edition of Dynamics we explore Multi-Disciplinary Design Optimization (or MDX), a methodology that allows engineers to automatically test designs against ALL of the physics that might ultimately influence the products performance during its operational life
CD-adapco™, the largest privately held CFD-focused provider of Computer Aided Engineering software has integrated SPEED™ with STAR-CCM+®. SPEED is the leading electric machine design tool and STAR-CCM+ a powerful all in one tool that models heat transfer, fluid dynamics, structural stresses, electric and magnetic fields, and aero-acoustics that play important roles in many electric machine applications.
Using the Adjoint Solver to Gain Greater Insight into Product Behavior
One of the greatest challenges of engineering analysis is being able to understand how changes in geometry and flow features might influence your system’s performance. For a long time, the only way to gain insight into the sensitivity of engineering objectives to changes in input was to run multiple analyses and then analyze the results. The introduction of the adjoint solver in STAR-CCM+ ® changes that paradigm, allowing for direct access to sensitivity information from a single simulation. This webcast provides an introduction to the adjoint solver, the background of the adjoint technique,...
Simulating Flow & Heat in Gas Turbine Engines - Part 3: Combustion
With nearly 80% of worldwide energy requirements being met by fossil fuels, combustion remains a key player in both the transportation and energy sectors. Consequently, gas turbine combustors are an integral part of combustion research and development. Simulation tools provide an ideal platform for the analysis and design of gas turbine combustors. Whether it is the prediction of gas turbine performance under various operating conditions, the optimization of combustor design for performance efficiency or to minimize emissions, scalable and cost-effective simulations of the complex physics...
