Are U interesting in general approach or exact formula?
Lets assume that we calculate it correctly. What after?]]> Thu, 29 Sep 2011 14:09:53 +0000 http://softinway.com/forum/forum_posts.asp?TID=146&PID=247#247 Usage of AxSTREAM Educational : Student contest In AxSTREAM.

Hi,

We in SIW are thinking about student contest. The goal is to present most interesting project available in educational version.
Preliminary schedule : 1-2 month EDU licenses provided for all students applied for contest. Then they present the brief description of their further projects. SIW selects say 10 most prospective and provides 3-4 month EDU licenses for projects completion.
Sure some awards are assumed.
This only an idea for now. What U think?

The accuracy om MoL is a critical question to any Design system. All MoLs are based on an approximations of some experimental results. So MoL accuracy depends on quality of source experiments, methods of approximations and how far is particular case from scope of experiments.
Commonly used method is "models identification". It used for any method of calculation including any advanced CFD.
Calculation results are compared with test data and MoL's tuning coefficients are used to adjust calculation results to experimental data.

There are at least two ways:


1. find good book for centrifugal turbine design and proceed with it.

 

2. take appropriative software. For example AxSTREAM Smile.

You can ask yor professor to apply for educational version. See info on SIW site.

hi, guys.
As the the cooling technique can be considered in Axstream, is there any loss model imported? 
and I'd like to know how do you define efficiency in cooled turbine. A specific furmula will be better.
Thank you!Smile

           Hello!

           What's about accuracy of Models of Losses (MoL)? Have you any verification results?
AxSTREAM has different types MoL, it's would be helpful to learn some recomendations from You about their using in different cases.
 
           Thank You!

Good day I am a student at the university of Johannesburg in South africa. I have been been given this project to work on but I am not sure where to start. I will be happy if you can help. The question is below:
 
Design a centrifugal turbine to drive the compressor. Assume the gas at inlet has a temperature of 1200 °C. To be compatible with the compressor, speed should be approximately 50 000 to 120 000 rpm.
 
Additional information:
 

Mass flow rate (kg/s)

Shaft power (kW)

Absolute pressure at inlet (kPa)

0.50

75

390

Dear colleague,

SoftinWay, Inc. started a new series of FREE web Demo, devoted to turbomachinery design and analysis in AxSTREAM III. 
 We hope that you find it interesting. Your feedback and opinion are vary valuable
