Virtual Powertrain Design: Simulating Engine Operation
Original Equipment Manufacturers (OEMs) are increasingly turning to computer aided simulation to help improve engine performance. They are finding that simulation-based design offers the greatest potential for cost savings, as the engine can be first broken down into different key components which influence performance. These key components vary from the intake port flow, in cylinder combustion process, to coolant flow, piston cooling, and even the oil flow patterns in the engine. There are certain test criteria that have been contingent on using only physical testing in the product...

【会议信息】 时间:2015年11月25日下午3:00-4:00 费用:免费(需事先注册) 语言:中文 注册方法: 希望参加本Webinar的客户,请从本页面的注册窗口进行注册。 【内容介绍】 CD-adapco公司很高兴的宣布,STAR-CCM+ v10.06版本已于2015年10月28日正式向全球用户发布。该版本最大的特色是增加了对一个新的工程学科计算——流变学的模拟功能,这样使得我们将多学科设计探索(MDX)这一CAE行业创新的使命又向前迈进了一步,帮助用户更快更好的寻找更优设计。 计算流变学功能进一步扩展了STAR-CCM+多学科求解的范围,能够解决粘性和粘弹性占主导的力学问题。现在可以应用于解决静态混合器的流动、流入容器、具有显著发热的泵送泥浆以及型材和材料加工。这一求解功能是建立在与v10.04发布的计算固体力学相同的有限元(FE)架构上的。 STAR-CCM+ v10.06其它主要新功能以及对已有功能的增强列举如下: 双向流固耦合:通过STAR-CCM+单一用户界面更容易实现紧密耦合,提高计算精度; 手动表面修复易用性增强:无论有经验的工程师还是新手,都能为其节省大量的工程时间; 基于查询的选择:使操作、显示和零部件的过滤和选择更加简单直观; 运用Parts-based的工作流程提高了基于Parts的Interfaces的性能和扩展性,...
This article details results from the numerical simulations on the NASA Trapezoidal Wing geometry, focusing on the high lift prediction using the CD-adapco solver STAR-CCM+. Computations and validation were based on the guidelines and experimental data provided for the 1st AIAA High Lift Prediction Workshop (HiLiftPW-1) to assess the numerical prediction capability of STAR-CCM+ for high lift configurations.
In this report, the performance of the Standard Cirrus glider is simulated using STAR-CCM+. To calculate the important transitional boundary layer flow, the Ȗ-Reș transition model is used. The study is performed to test the quality of the transition model and to create a validated reference model of the glider’s performance in steady level flight. The validated model will in future studies be used to improve the performance and handling quality of the glider and serve as a reference model for other simulation tools.
STAR-CCM+ is developed to be accurate, efficient, easy to use, and, thanks to its rapid release cycle of three major releases each year, to grow with the needs of our users in mind. We are always improving the technology and capabilities to better solve the problems facing the aerospace industry. This article highlights a few recent and upcoming capabilities.
One of the greatest challenges facing the aerospace industry is improving the aeroacoustic noise generation of their products to meet today’s more and more stringent noise pollution standards. As flow-induced noise makes a significant contribution to the overall output decibels, it seems essential to understand how to optimize the aircraft design in order to minimize the flow-induced noise without impairing the general performance of the air-vehicle.
In today’s competitive climate, driven by climbing fuel costs and increasing demand for air travel, high-fidelity CAe is a key enabling technology for aerospace companies to develop innovative minimum structural weight designs while meeting the tight schedule and cost constraints of a typical production environment. It is imperative that the CAe capability is accurate, robust and efficient and that it easily fits into the current engineering design processes, producing high-quality results with minimum user efforts. With its unrivaled meshing technology, high-fidelity physics, intuitive user...
Sikorsky Aircraft set out to explore an alternate method of predicting hub drag of production geometries based on numerical simulation. This method can provide a reasonable prediction of hub drag for different designs in a short time period, allowing easier optimization of component design in a production environment. This article showcases the application of CD-adapco’s unstructured Navier Stokes solver, STAR-CCM+, to the blind prediction of hub drag on two production rotor hub geometries, the S-92A hub and the UH-60A hub.
Develop an aircraft design concept and design aids/mockup that will illustrate that the key performance requirements stated in this document were met in addition to the mission success and safety of the occupants were ensured. Concepts can be demonstrated or illustrated in many ways – choose the most appropriate and cost eff ective (paper/pencil, trade studies, desk top models, charts, mini-demos, electronic simulations, analysis tools, etc.). Develop innovative concept ideas in an integrated fashion to show traceability to meeting the requirements – both stated and derived.”
The 2013-2014 AerosPACE course partners are The Boeing Company, Brigham Young University, Embry-Riddle Aeronautical University, Georgia Institute of Technology and Purdue University. Teams consisting of students from each university were asked to design, build and test a UAV that can monitor agricultural fields to improve crop yield. The UAV must meet various mission parameters.
