In an effort to improve ORC radial turbine performance and design, several concepts have recently been investigated. Nevertheless, there aren't many thorough studies that take into account how various elements affect the performance of radial turbines. Therefore, the objective and the interest of the present work is to create a 1-D algorithm that c...

Hi everyone,
I`m simulating a gas dispersion problem using Multi-component transport species (without reaction) in ANSYS-FLUENT. I`m considering the dispersion of one species (H2S) using the cell zone modeling, so I will have only H2S and air. I would like to consider the dispersion of H2S with a mass flow rate equal to 7 (kg/s) and the H2S should have a mass fraction equal to 0.29 (kg/m3). In Fluent inputs as in the attached file, there is an option to define the Mass source and also the H2S source ! I`m confusing where to define mass fraction of the H2S and where to define the mass flow rate ? based on the cell zone method !
Is the Mass source in the attached file means the total mass flow rate of the H2S ? and is the H2S source means the mass fraction of H2S ?
I would be grateful if anyone can clarify this for me ?
Regards,
Abdelkader
Hi all,
I have developed a code using Fortan included in the Microsoft Visual Studio 2010. I would like to create a graphical user interface GUI for this code but I don`t know how to do that in easier manner.
Could anyone please share his experience on such coding development ? is the Microsoft Visual Studio 2010 can do that or should I use other programming languages such Visual Basic, or Delphi or ... to do that ? I`m really confusing on how to start doing this and I would appreciate any suggestion and help.

Dear all
