    Study of FLAME anf CONDENSATION in a heat exchanger (HRSG system),

    Good afternoon, I have a trouble in resolve an industrial problem for heat exchanger type: HRSG. The study will be made using ANSYS FLUENT. My trouble occurs because in first step must to optimized the fluid flow of hot air inside of HRSG, especial in first portion of circuit, after burner. The...

    Culculus of radial velocity and tangential velocity for cylindrical fan !?

    Good morning, How I can calculate axial velocity, radial velocity and tangential velocity for an centrifugal fan ? Only what I know is outlet mass flow (Q [m^3/s], speed of motor [rpm], pressure at outlet from fan. The axial velocity I can found it from relation Va=Q/S. For tangential and...

    Visualize results from ANSYS Ls-Dyna,

    Good morning, I used ANSYS 14.5 and I want to know how to visualize the results from ANSYS Ls-Dyna, because from WB is saved only .K file and I can solve it only with application from ANSYS Launcher (both with parallel processing). I am in doubt about visualization of results, because I don´t...

    Submodelling in ANSYS 14.5

    Good morning, I using ANSYS 14.5 to made structural static and transient study. Sometimes, because of complexity of geometry I cannot made quality mesh from the point of view of results (stress especial). From this reason I used submodeling technique. My question is if somebody can help me with...

    Magnetic field,

    [ponder]Good morning, I have a question reffering to magnetic field (B): Considering an cylindrical magnet (dipole) in plane (resulting an rectangle). If magnetic field can be determinate analithic (aproximate) in vertical axe (axial), how can be determinate analithic magnetic field tangential...

    ANSYS LS-DYNA export,

    Good morning, I have the next situation: to resolve the impact of sloshing water in a tank in a moment of seism. To do this study I will used ANSYS LS-DYNA (from ANSYS 14). I observed that, if I will used as preprocessor ANSYS LS-DYNA from ANSYS WORKBENCH interface, they export only .k file...

    Wire diameter for magnetic generator?

    Hi all, I read very carefully documentations recomanded, but I am in doubt with some things. First of all, from my point of view the power of magnet must be depend on "power" of magnet, section area of magnet and air gap betweens surfaces of magnets (or magnet and ferometalic material) (this...
