Hello guys and girls,
I have a problem to which I tried some stuff with Ansys Fluent, but I donīt get it or maybe I have taken the wrong route to it.  This is the problem I am trying to solve in ANSYS Fluent. I have a plasmastream source with a diameter of about 20 mm, at 1 bar and a temperature of 2500 K which streams at a sample holder with about 0,5 kg/s. (For simulation purposes I could assume that it is just air with 2500K) This hits a round cylindrical Sample Holder which consists of a ceramic (0.1 W/mē thermal conductivity) and a sample (10 W/mē) inside the ceramic middle part so that it "sees" the stream. I propably have convection outside of the ceramic, since the stream flows around the sample and heat is radiated from the ceramic and the sample to the outside air at 300K. If possible, could someone maybe give me some advice on how I could simulate that problem in Fluent or CFX ? Thank you very much ! Best Regards Christian |
