ANSYS, Stanford & Honeywell Join for Fuel-Efficient Aircraft Engines

Engineers from Stanford University, Honeywell International and ANSYS are working together with simulation software to create more energy-efficient aircraft engines at lower costs.

As demand grows for increased gas turbine efficiency, engine manufacturers are challenged with creating designs that operate at higher temperatures. But that becomes a significant challenge as temperatures approach the melting point of some engine component material. A well-established method for maintaining turbine blade temperatures at acceptable levels is to employ “film-cooling,” a technique in which cooler, compressor-discharge air is detoured around the combustor then ejected from precisely-machined holes placed over the surface of the turbine airfoil. Excessive use of compressor air for turbine film cooling can, however, reduce engine efficiency.

Historically, film-cooling-hole-placement on turbine airfoils has been optimized by elaborate experiments, sometimes necessitating engine testing. For decades, research engineers have been developing computer simulations of film cooling geometries with the ambition of reducing – if not eliminating – the need for expensive, time-consuming rig testing.

Stanford, with support from Honeywell and ANSYS, is performing a new type of testing with 3-D magnetic resonance velocimetry to measure the velocity and concentration field in a test section. These methods measure the turbulent interaction of crossflow jets with the main flow, for a variety of jet configurations and orientations. These data sets provide an important benchmark against which the large available range of ANSYS turbulence models and computational methods can be compared. The objective is to develop validated models, methods and best practices for prediction of film cooling.

"This is the first time that an engineering software company has supported an extensive test series like this, and it illustrates the commitment of ANSYS to the continued upgrade of the turbulence models in ANSYS computational fluid dynamics solutions," said John K. Eaton, the Charles Lee Powell Foundation professor in Stanford’s School of Engineering. “Our combined efforts are aimed at validating the turbulent mixing models in these tools over entire complex flow fields, something that has never been done before. Conducting this testing over a wide range of film cooling conditions provides a comprehensive test of the predictive capability."

“At 30,000 feet in the air, there’s little margin for error,” said Brad Hutchinson, global industry director for industrial equipment and rotating machinery at ANSYS. “By always focusing on solving the most complex problems – like the thin film cooling challenge Honeywell and Stanford are addressing – ANSYS ensures that our customers are armed with the tools that will help them to create the most innovative products on the market.” 

IT Services Develops Three-Phased Approach for FATCA Quality Assurance

Mindtree, a global technology services company, today released results of their Strategies for Achieving FATCA Compliance survey.  Conducted in May and June 2014, the survey examined the challenges that risk, compliance and IT decision makers face in achieving FATCA compliance. 

 “This survey reinforces that there are still many hurdles to be overcome to become FATCA compliant,” said Gaurav Johri, Senior Vice President and Head of Banking, Financial Services and Insurance at Mindtree. He added, “What most risk, compliance and IT decision makers need to understand is that executing a comprehensive product assessment helps avoid unintended impact of FATCA on their offerings. An assessment validates the way a FATCA-compliant product is offered while dealing with the variables of the client, their location and the generation of US sourced Fixed, Annual, Determinable or Periodic (FDAP) income.”

Complying with FATCA through a product assessment is a complex task with multiple work-streams. To assist financial institutions, Mindtree has developed a FATCA quality assurance pack to reduce testing effort and costs up to 20%, identify gaps in the implementation process, report issues to stakeholders and enable informed decision-making. 

Part one of the pack focuses on test planning to assess the FATCA implementation and design a scope for data-centric, functional, performance, security and interface testing. Part two centers on the test automation, agile testing and product assessment. The third and final part of the pack examines the test results and identifies gaps.

Thrust Laid On Tech Innovation At Indo-US Summit Welcomed

The National Association of Software and Services Companies (NASSCOM) welcomes the recently concluded bilateral summit between the United States and India. The Summit was focused on discussing broad Strategic and Global partnership between the two countries and establish continued prosperity and security for their citizens and the world. During his visit, Prime Minister Narendra Modi emphasized on the priority India accords to its partnership with the United States, a principal partner in the realization of India’s rise as a responsible and influential world power. 

 The two leaders recognized that the bilateral relationship between the two nations enjoys strong support in both countries, which has allowed the strategic partnership to flourish even post the change in government. Both leaders agreed to revitalize the existing partnership and find new areas for collaboration and mutual benefit. The bilateral summit laid additional focus on the need to foster innovation in a manner that promotes economic growth and job creation and to recognize in particular the contribution of the Indian and U.S. IT/ITES industry in strengthening India-U.S. trade and investment relations. 

Expressing his views, R Chandrashekhar, President, NASSCOM, said, “We are delighted with the enthusiastic welcome that PM Modi received in the U.S. – from the White House, from hundreds of American business leaders, and from the citizens of the U.S. NASSCOM is encouraged by President Obama and Prime Minister Modi’s recognition to the contributions of ICT sectors in the U.S. and India, and the synergies produced when these important sectors work together to resolve issues, innovate, and invigorate both  nations’ economies. We also welcome restarting collaborative dialogues such as TPF forum. NASSCOM has been working with the government to ease the trade relations and will continue to advocate for the removal of existing impediments and the prevention of additional barriers for India-based IT services companies providing valuable services to customers in the U.S.”

 At the summit, both the countries also recognized the critical role played by the U.S. and Indian businesses in sustainable, inclusive, and job-led growth and development. We welcome US and India partnership on the Digital India initiative and US industry to be lead partner in developing smart cities in Ajmer (Rajasthan), Vishakhapatnam (Andhra Pradesh) and Allahabad (Uttar Pradesh). At the bilateral summit, the Prime Minister also mentioned the two trade missions to be organised in 2015 which will focused on meeting India’s infrastructure needs with U.S. technology and services.
