AxSTREAM in University Programs

AxSTREAM IS GEARED FOR LUISIANA UNIVERSITY TURBOMACHINERY EDUCATION

FOR IMMEDIATE RELEASE

BURLINGTON, Massachusetts, June 22, 2005

SoftInWay, Inc., the developer of AxSTREAM™ - a powerful software suite that encompasses the complete engineering process of axial turbomachinery flow path conceptual design and optimization continues its education line in the way of inclusion of this flagship product in various education courses.

'We have developed educational programs for all who want to learn, improve or expand their knowledge in turbomachinery design. Our programs benefit undergraduates, graduates, teachers, professional designers and retrofitters, all of who, using our rapid and reliable design tools' - says Leonid Moroz, President and CEO of SoftInWay. - 'Recently, the Mechanical Engineering Department of Louisiana State University (LSU) has chosen to include AxSTREAM in their Turbomachinery Program. We are pleased with their decision to incorporate our software into their curriculum because LSU places high emphasis on turbomachinery academic, research and educational activities, making a real contribution to the industry science and practice.'

Dr. Shengmin Guo, LSU Mechanical Engineering Faculty Assistant Professor and instructor of the ME 4853 course Turbomachinery, said: "The educational version of AxSTREAM offered to us by SoftInWay covers all basic lines in turbine design and optimization. We were able to effortlessly integrate the AxSTREAM tool into the learning process as an efficiency assistant for students.' Dr. Guo also added: 'I am very pleased to report that most of students learned to use AxSTREAM, which helped enhance the theoretical matters encompassed by the course. Naturally, it took them some time to figure out how to set the important performance parameters and how to evaluate the effect of varying those parameters on the overall performance of the turbine. AxSTREAM enabled the students to examine the relationships between path parameters and blade shapes, making it a very useful supporting educational tool. Spanning the concepts-to-details process of axial turbine design and retrofitting, the tool enriched the students with application-oriented guidelines for new and existing turbine flow path designs along with real design techniques for the entire flow path and its optimization. In some of my students' opinion, this software has been one of the best they have worked with in their Mechanical Engineering curriculum.'

Being a company deeply committed to future engineers' solid knowledge of turbomachinery design, SoftInWay offers AxSTREAM for use in the turbomachinery courses of educational entities worldwide.

The AxSTREAM™ software suite can be downloaded for evaluation. Please request by writing to tech_suppot@softinway.com.

LEANED AIRFOILS DESIGN USING AxSTREAM

AxSTREAM turbine design suite gives an opportunity to design swept and leaned airfoils. Both lean and sweep can be as constant as arbitrary along the blade height, in the last case defined by cross-section offsets.

Airfoil surfaces designed with AxSTREAM can be exported in IGES format. Export of the airfoil geometry can be performed as the cross-section contours to build 3D CFD models (CFX, Fluent).

AxSTREAM turbine design software provides sufficient precision to calculate a leaned airfoil performance using axisymmetric stage analysis. AxSTREAM finds optimization solutions for leaned airfoils with the lean both constant along blade height and arbitrary with station offsets.

This paper presents:
1. Samples of leaned and swept airfoils designed with AxSTREAM;
2. Comparison of leaned airfoil calculation results for two solver types: 2D (AxSTREAM axisymmetric solver) and 3D CFD (CFX).

1. Samples of Leaned and Swept Airfoils Designed with AxSTREAM


Fig 1.1 Original model - cylindrical nozzle	Fig 1.2 Nozzle with constant sweep + 10 degrees

Fig 1.3 Nozzle with varied sweep of "Ñ" type	Fig 1.4 Nozzle with varied sweep of "S" type

The pictures above show how AxSTREAM calculates stage parameters with regard to lean.

2. Data Comparison 2.1 Comparison of AxSTREAM and 3D CFD
	Fig. 2.1 Parameters distribution in upstream stator with cylindrical blades
	Fig. 2.2 Parameters distribution in upstream stator with constant lean As it is shown in the diagrams, the result of constant nozzle lean is validation of the predicted effect - a decrease of static pressure gradient in the downstream stator gap.
	Fig. 2.3 Parameters distribution in upstream stator with varied lean of "S" type. S-formed nozzle was created arbitrary with the only aim to illustrate the lean effect and to carry out this calculation. As it is shown in the charts, the applied cross-section offsets near the root and at the periphery of the blade does not influence the flow structure substantially. Parameters near the mean-line remained unchanged, and the gradient slightly decreases in the direction of edge surfaces.

SoftInWay Through the Prizm of Events

SoftInWay on the ASME Anniversary Global Gas Turbine Event

ASME TURBO EXPO 2005- Power for Land, Sea and Air is celebrating its 50th anniversary in 2005. Grand show as it always was, this ASME ANNIVERSARY TURBO EXPO had gathered over 2000 of participants, including engineers, research scientists, and other professionals from across the world. The event included a keynote session titled "Gas Turbine Technology: Focus for the Future," featuring a panel of leading executives from the power generation industry. The event also hosted a major equipment exposition showcasing new and advanced products and systems, plus a Technical Congress featuring more than 600 papers and tutorials.

A booth with SoftInWay's AxSTREAM^™ and AxPLAN^™software had attracted a bulk of visitors searching for the integrated, robust and cost-effective solutions for turbomachinery design. A list spans current and future users of all categories beginning from students and teachers through designers and consulters to manufacturers and retrofitters.
