The enormous breadth of applications for which STAR-CCM+ is being used is in part a result of the deep range of options available for all steps of the simulation process - from CAD to meshing to conditions and physics to solving and post-processing. But the range of options comes with a price: Sometimes it can be difficult to know the particular settings most appropriate for a given application. This presentation will overview the recommended STAR-CCM+ settings for typical electronics cooling analyses. All steps of the simulation process will be systematically addressed, with explanations of...
CFD has been a common tool in thermal design of electronics for many years. The first electronics-focused CFD program came out nearly 30 years ago, and currently there are no less than 6 CFD-based programs that focus solely on electronics thermal applications. So it is fair - and right - to ask, what can STAR-CCM+ bring to this application area? Why would people use STAR-CCM+ over any of the other tools? This presentation will explore how the author predicts electronics thermal simulations will advance in the next 5 - 10 years. The context for the advancements rests with the historical and...
Engineering simulation impacts a wide range of external aerodynamic applications such as fuel economy, maneuverability and noise. With demanding schedules, shrinking resources and a competitive market, engineers need to obtain accurate results as quickly and efficiently as possible. This presentation will cover best-practice techniques to model a range of aerodynamic conditions for aerospace applications. You will learn which physics models, numerical schemes, turbulence models, meshing strategies, and optimization techniques are best-suited for this class of simulation problem. With this...
This study looked into the DES simulations of the eight bladed NASA SR-2 propeller. The 24.5 inch diameter propeller was simulated at Mach 0.6, with and without the presence of a straight aft wing of NACA0010 profile, to investigate the effects on the level of aero-acoustic noise detected on 12 microphone probes. The geometry of the straight-blade SR-2 propeller, along with the area-ruled spinner and contoured nacelle, were generated within the simulations based on available literature. The acoustic plate, housing all the microphones, was included in the simulations so as to provide a better...
Free shear turbulent noise is prevalent in many engineering applications. Study of the noise generation mechanism in such flows using DNS is not computationally realistic. LES, however, offers a significantly less expensive solution while maintaining similar modelling capability as that of DNS. The classical test case chosen for this study is a generic Mach 0.75 round jet flow. This study focuses on investigating the roles of shear layer instabilities and large scale coherent structures in free shear flow aeroacoustics. Inflow conditions were treated in this study to provide a realistic yet...
