Mixing Simulation with Ease: Automating the Simulation Set-up Process
Poor mixing can result in the loss of millions of dollars within the chemical, pharmaceutical and many allied industries. Computational Fluid Dynamics (CFD) simulation is used to answer the numerous challenges that cannot be solved by analytical or experimental methods. This is especially important in the design and scale-up phases of process development. A common hurdle in performing simulation mixing for engineers who are new to simulation is the significant amount of time required to set up geometry, meshing and adequate physics. Even for experienced simulation experts, creating both...

The performance of the Standard Cirrus glider is simulated using a Computational Fluid Dynamics code, solving the incompressible Navier-Stokes equations for steady flow. To calculate the transitional boundary layer flow a correlationbased transition model is used. It is found that the numerical model is able to predict the performance of the Standard Cirrus well. The simulations using the transition model are found to improve the results compared to fully turbulent simulations, except for the region of the stall. The best in-flight measured glide ratio for the Standard Cirrus is 36.5 at 94.5...
Computational Fluid Dynamics is routinely used in clearance of stores for carriage and release from aircraft in the transonic range of flight. A well-known validation case is modelled in this study, for which aerodynamic loads have been compared with wind tunnel experimental data by other authors. In this study, having validated the numerical model, we apply more recent methodologies from flow dynamics to study the detailed flow field in the region of the store fins.

Increase Productivity by Closing the Gap Between CAD and Analysis with Automated Workflows
Dealing with the consequences of imperfect CAD has long been one of the biggest bottlenecks in CFD. Furthermore, reducing the costly process of manual CAD clean-up ensures an engineer's valuable time is instead spent gaining insight into product behavior and performance. This webcast demonstrates how to: Use a fully parametric 3D-feature based modeler to easily create and modify your own geometries Use automatic bi-directional geometry updates between CAD and simulations during the optimization process to facilitate Multidisciplinary Design Exploration (MDX) Eliminate manual repair from the...
