Recent advances in automated mesh generation, availability of high-fidelity and fully-coupled physics, and increased computational power are necessary and enabling factors for CFD-based design of next generation rotor-craft systems. The incorporation of CFD estimates early in the design stage is beneficial for obtaining improved performance predictions as well as to reduce the number of design iterations required. It is with this aim that numerous physics capabilities and enhancements were added to STAR-CCM+ for complete rotorcraft simulations. Rotor performance prediction methods available...
'The hardware for a Mars exploration mission shall be designed to operate during exposure to the Martian dust devil winds. The current numerical investigation aims to predict the aerodynamic loads and the convective heat transfer coefficient on the surface of the geophysical instruments deployed on Mars. An additional issue is the stability analysis of the payload, according to the maximum ground slope detected. A detailed 3D model of the instruments has been realized, discretizing the fluid domain with a high-resolution volume grid of more than 3 million tetrahedral cells. The Martian flow...
Transport phenomena in multiphase processes play a major role in many industrial applications and scientific investigations. One of the most interesting aspects is the study of mass transfer and hydrodynamic behavior in gas/liquid and liquid/liquid systems which often show complex mutual interactions. Beside simulations experimental investigations in multiphase systems were carried out to study phenomena such as drop breakage, drop coalescence or interfacial instabilities. Optical in situ measurements provide local information pertaining to the volume fraction as well as drop-size...
At the University of Southampton, the author has been teaching and designing the M-level module-applications of CFD using software such as CD-adapco's STAR-CCM+ since 2009. This 10-credit module is for MSc and MEng of Aero, Mech and Maritime programmes. Students enjoy using the latest CFD technology and learning updated case studies. Although these increase teaching workload, they are worthwhile indeed. Some examples will be given in the presentation. As the class has evolved over the last 6-year, the number of students taking the module has been growing steadily from over 40 to over 60 in...
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...
