Better Electronics System Design with Detailed Fan and Blower Simulations
This webcast explores in detail the typical method for testing fans and blowers, the inherent assumptions in the test procedures and several methods of simulating fans. Particular insights into the air flow produced by fans and blowers will be demonstrated along with potential extensions of the data such as aeroacoustic noise. The vast majority of electronic systems are cooled using fans or blowers to move air over heat exchange devices such as heat sinks. The fans and blowers are typically characterized by a performance (PQ) curve that shows the relationship between the flow that can be...
Counter-Current Flow in a Pressurized Water Reactor [Deendarlianto et al., NED, 39 (2012)]
STAR-CCM+ simulation of Counter-Current Flow in a Pressurized Water Reactor using Large Scale Interface Model
Rarely in life do we get the chance to get more for less, and the world of simulation is no different, or at least not until now. Typically in our simulations we have to make compromises, and in choosing those compromises we need to know which models will give us the best information at the minimum cost. We must also understand the assumptions our choices carry and how these might influence the decisions we make. This after all is the art of being a good Simulation Engineer. Before we begin and lose ourselves in the wonders of multiphase, imagine if you will a beach, the sun is beating down, the wind is blowing and the surf is up. The sea looks a little rough, but being a good Simulation Engineer the foamy seas pose no worries to you and your recent lunch…..
국방/항공 분야에서 중첩격자 기술(Overset Mesh)의 활용
중첩격자 기술(또는 키메라 격자)은 수십 여년 동안 있던 기술이지만 주로 일부 공력분야에서만 사용되어 왔습니다. 중첩격자 해석 툴들은 최근에는 특정 응용분야에 맞게 사용되도록 개발되고 있습니다. 하지만 그 나름대로 강력한 기능에도 불구하고 실제 사용하기에는 여전히 쉽지 않은 면이 있습니다. 본 영상에서 보여드리는 데모 시연에서는 중첩 격자를 사용한 형상준비, 격자 생성, 해석 및 후처리 과정을 포함한 전체적인 해석 프로세스를 시연할 예정입니다. 다음과 같은 몇 가지 응용 사례를 통해 중첩 격자의 장점에 대해 알려드리도록 하겠습니다. • 항공기/우주선 분리 • 항공기 제어 표면(Control Surface) 성능 • 역추진 장치 전개 • 회전익 항공기의 이착륙 • 수중양용차량의 입수 • 차량 침수와 물 관리 • 기어박스 윤활 • 밸브, 댐퍼 및 펌프 지상, 육상 및 해상 운송수단들에 대한 연구에 종사 중이신 분들에게는 유익한 강의가 될 것입니다. 이미 중첩 격자를 사용하셨던 경험을 가지고 계시더라도 관련 기술이 어느 정도 발전되었고, 모델링의 정확도 향상, 계산 시간 단축 및 설계 개선을 위해 얼마나 쉽게 사용할 수 있는지에 대해 다루게 될 것입니다.
Using Simulation for Cost Effective Mixing within the Chemical Industries
Mixing is a very common application within the chemical, pharmaceutical and many allied industries, where streams are mixed to achieve homogeneous distribution. Despite its widespread use, many challenges remain in the analysis of mixing applications. Every year, billions worth of production is lost due to poor mixing. Analytical methods and experimental measurements answer many of these challenges. However, there are many unknowns that arise during: Scale-up New designs or multiple internals in equipment Special operating conditions or troubleshooting These unknowns cannot be answered by the...

One warm July morning buddy of mine and I decided that we needed to hit the lakes and go catch "the big one". We headed out just as dawn broke so we can find that big old bass that I knew was hidden somewhere in our favorite spot. Once we got the boat in the water it is about a 15 minute ride across the lake over to the spot where our fish was bound to be. So a cup of coffee in hand we sped off across the lake, during that time one’s mind always tends to wander and apparently mine wanders back to meshing. Looking across the still lake nothing much is going on but behind the boat is a whole different story; the propeller is stirring up quite a bit of turbulence and the hull is producing a massive wake, this is where the action is. So I ask to myself, what kind of tools would our users need in order to build meshes automatically in order to capture this type of phenomena? A tool that would allow efficient meshes and could give accurate answers with a minimal cells count. STAR-CCM+ v10.02 meshing operation allows users to refine wake zones in both the polyhedral and the trim meshers as well as give wake a draft angle so that the refinement zone expands as it moves away from the model.
