Using CFD to Design More Efficient Combustion Systems
Combustion is the major source of energy in the world today. Improving the efficiency of combustion systems is not only critical from an economic perspective, but it greatly impacts the environment and long-term sustainability of our planet. Experiments and prototyping are expensive due to the complexity and high temperatures involved in combustion systems. Therefore, CFD simulation is a key enabling technology for designing better combustion and aftertreatment systems. Combustion engineers are now integrating simulation up front in their design processes to increase efficiency and reduce...
The Virtual Refinery: An Introduction to CFD in Downstream (Refining and Petrochemical) Operations
If you are involved in equipment design, maximizing refinery uptime and efficiency, troubleshooting problems or preparing for turnarounds, and are interested in the latest flow and thermal simulation technology, this webinar is for you. Whether it is maldistribution of flow causing catalyst exhaustion, separation, combustion, thermal fatigue of mixing tees or coking, successful management of fluid and particle dynamics and heat transfer are critical for maximizing refinery uptime and process efficiency. Achieving process efficiency at the plant scale requires strong performance of individual...
In STAR-CCM+® v11.04, the highly regarded (extended) pom-pom adds to our list of viscoelastic constitutive models. Best suited for highly branched polymers like low density polyethylene (LDPE), it is able to most accurately predict viscoelastic responses for elongational flows commonly encountered in industrial processing.
Fluid-Structure Interaction (FSI) is the study of thermo-mechanical interactions of a fluid and a solid structure. FSI modeling for implant device design is taking on even greater importance in the current medical device environment, as producing better designs, faster, is imperative in this industry to reduce operating costs and introduce necessary potentially live-saving devices to market.
STAR-CCM+를 이용한 소음 해석 기술
지난 수 십 년간 인류는 여러 산업 분야에서 눈부신 기술 발전을 이룩하였습니다. 이러한 기술 발전은 우리에게 많은 혜택을 안겨 주었지만, 부정적인 측면도 발생 하게 되었습니다. 그 중 환경오염 문제 해결에 대한 요구가 증가하고 있고 특히 소음 문제는 근래에 사회적 이슈로 대두 되고 있습니다. 이러한 소음 문제를 해결하기 위해서 최근에 컴퓨터를 이용한 해석 기술이 많이 이용되고 있습니다. 향상된 알고리즘과 계산 능력으로 인해 유동 소음 해석 분야에서도 시뮬레이션을 통한 소음 저감 노력이 활발하게 진행 되고 있습니다. 특히 소음의 발생 매커니즘과 음의 전파를 해석하기에 더욱 수월해졌습니다. 이번 동영상에서는 STAR-CCM+를 사용한 소음 해석 기법 소개 및 다양한 적용 사례를 통해 실제 제품 개발에 응용하기 위한 소음 해석 기법에 대한 이해를 높이고자 합니다. 주요 발표 내용은 다음과 같습니다. 주요 내용 소음 해석 소개 Direct Noise Calculations Aeroacoustics in STAR-CCM+ Ffowcs-Williams & Hawkings Acoustic Wave Solver Surface FFT
At this year's AIAA SCITECH annual conference, I sat down with the editors of Aerospace America to talk about the future of CFD analysis in the aerospace and defense market. Predicting the future of CFD is the subject of intense debate. The recent publication of the NASA led CFD Vision 2030 study attempted to define the key challenges that face the industry over the next 15 years. In the report, the authors identified several obstacles to wider adoption of CFD in the aerospace industry: Limited Funding : NASA investment in basic research has declined significantly over the last few years...
The Next Big Thing in Hydrodynamic Optimization of Ship Hulls
Still water resistance has been the traditional way of optimizing ship hulls since the time of William Froude. In the last few years, hydrodynamic optimization of hulls has been carried out with consideration to their operating profiles as opposed to design condition alone. However, ships sail in waves most of the time, so how can the resistance of the hull in waves be improved? The answer is positive: the potential, especially in short waves, is far from being negligible. On the other hand, optimization for minimization of added resistance in waves is far from trivial, due to the difficulty...
Keeping It Cool in STAR-CCM+
As a general-purpose simulation tool, STAR-CCM+® is used for applications in almost every industry where products are developed - automotive, aerospace, marine, oil & gas, energy, nuclear, life sciences, chemical processing…and electronics. Thermal simulations are the most common in electronics companies, but many of the other industries also frequently involve electronics cooling applications. In electronics, cooling temperature prediction and control is the primary goal of the simulations - which requires full conjugate heat transfer of conduction, convection, and radiation - whether...
The demand for safe and efficient Li-ion batteries has never been as high as it is today. By coupling Battery Design Studio® to HEEDS® MDO, battery manufacturers can intelligently drive their designs through a range of design parameters and operating conditions. This speeds up the design process, facilitates innovation and helps battery designers stay ahead of the competition.
