Fire in an aircraft cockpit
Simulation showing spreading of fire in the cockpit of a Hawker Hurricane. This helps in understanding and analyzing fire suppression systems in the cockpit.
CD-adapco™, the largest privately held CFD-focused provider of Computer Aided Engineering software, today unveiled wave6, a new software product line for vibro-acoustic and aero-vibro-acoustic simulation. The new products will complement and extend the functionality of the company’s flagship simulation tool, STAR-CCM+®, to address flow-induced noise and vibration problems.
더 나은 전자 시스템 설계를 위한 팬과 송풍기 시뮬레이션
이번 온라인 동영상에서는 팬과 송풍기 테스팅의 일반적인 방법과 테스트 과정에 내재된 가정, 그리고 팬을 시뮬레이션하는 다양한 방법에 대하여 상세하게 살펴볼 예정입니다. 팬과 송풍기에서 생성된 공기 유동에 대한 이해와 공력 소음과 같은 데이터로의 확장 가능성을 함께 보여드릴 예정입니다. 전자 시스템의 대부분은 히트 싱크(Heat Sink)와 같은 열 교환 장치를 통해 공기를 이동시켜 팬 또는 송풍기를 사용하여 냉각하고 있습니다. 일반적으로 이러한 팬과 송풍기는 압력의 범위 내에서 해석되면서 나타나는 유체의 성능 곡선(PQ)으로 특징지어집니다. 설계 엔지니어들은 특정 시스템에서 택한 팬의 실제 공기 유동을 예측하기 위해 시스템 저항 특성과 PQ곡선의 교점으로 사용할 수 있습니다. 팬의 다운스트림 또는 업스트림에 상당한 유동 장애를 일으키거나 PQ 곡선으로 예측할 수 없는 유동간 상호작용을 유발하는 팬의 구성을 포함한 시스템 예제를 보여드립니다. 이와 같은 상세한 사례를 통한 팬 또는 송풍기 시뮬레이션 온라인 세미나는 설계자들에게 냉각 현상에 대한 이해를 크게 높일 수 있는 자료가될 것 입니다.
Is a picture worth a thousand words? Some are, some aren’t — but why? When it comes to presenting simulation results, it is not an easy question to answer or anticipate. While we are fully engaged in projects, we learn a lot about the devices and processes we are modeling. With excessive amounts of data being generated in the face of fast-approaching deadlines and our target audiences needing to form their own thousand-word narratives, it is easy to lose sight of our primary objective: delivering something in an efficient and effective way that enables others to see problems immediately and...
Optimized Drive-cycle Performance and Thermal Analysis
Electric motor design is a complicated task that requires the designer to consider many tradeoffs — this process can be successfully enhanced with the help of advanced optimization algorithms and detailed 3D thermal analysis. This webcast explores the design of a traction motor application for a mid-sized electric vehicle and maximize the machine efficiency averaged over the US06 drive cycle (considered an aggressive acceleration drive-cycle). A 3D transient thermal simulation over the drive cycle is then performed to determine under what condition the motor reaches worst-case temperatures...
We will discuss how STAR-CCM+ ® Computational Fluid Dynamics software can be used to help in the design of energy efficient buildings. Some areas include fire and smoke modeling, cleanroom studies, wind dispersion, thermal comfort, solar loading, pedestrian comfort and other building-related analyses. Each discipline carries with it, numerous opportunities to simultaneously improve energy efficiency and human safety. There is also a hands-on session to solve an HVAC problem. Put your engineering skills to the test and create a better design than your neighbor! No previous training required.
With presentations from CD-adapco™ and Kimberly-Clark, this workshop will detail how customers benefit from seamless, easy-to-use, and robust fluid-structure interaction solutions using STAR-CCM+, as well as how you can link leading Finite Element Analysis (FEA) tools such as SIMULIA’s Abaqus.
Eliminating environmental or other airborne contaminants within medical, biological research and production facilities is critical to the success of their mission. The use of CFD allows for a non-intrusive way of determining air conditions of a room without concern for operator safety potentially disturbing a measurement. In this webinar we will demonstrate how CFD is used for analysis and optimization in several environments: be it determining ventilation rates in an operating room, playing a critical role in minimizing the rate of infection from airborne bacteria and viruses; or a study of...
Multi-stage turbomachinery flow-fields are inherently unsteady. Accurately capturing unsteady flow features such as tip vortex motion and blade-row interaction is important for properly predicting machine performance and thermal profiles. Modeling these unsteady features provides greater insight into the transient nature of the system, and is also necessary for accurate prediction of time-averaged quantities such as efficiency and blade temperature. Traditional time-marching unsteady methods are often accompanied by prohibitive expense with regard to computational cost. The harmonic balance...
