(Multiphase)"},"content":{"rendered":"

Hello, I am new to Ansys and have been learning from tutorials and previous forums posts, please forgive my lack of technical knowledge and bad wording.  <\/p>\n

I am trying to do a simple thermal analysis on a enclosed chamber where half is filled with (static) water, the rest air, and a Silicon wafer heat source at the bottom. I’m assuming Fluent is the best option and the option I was told to use. I’ve also thought about steady state thermal but at some point I will have to simulate a moving body of water so I was hoping to get adapted to Fluent.<\/p>\n

The model was made in SolidWorks and imported. In the meshing stage I created named selections for the air, water, Si wafer, and the container itself (steel 0.2mm thickness). I changed the mesh sizing for water and air to .006 m and the container .009 m in hopes of getting a more accurate result.<\/p>\n

The Silicon wafer will be set to 65C. I would like to have convection and conduction included in the results. I am trying to see the temperature contours in general and see if they align with the physical experiments. <\/p>\n

Initially I was trying to do this wthout the use of Multiphase but I was getting:<\/p>\n

”Warning: zone of type interior found between different fluids!…” <\/div>\n
 <\/div>\n
After some googling someone said it’s not as simple as setting cell zone materials and I would need to turn on multiphase but now I’m more lost as to how to complete the analysis. I’m also unsure if this is the right approach. <\/div>\n
 <\/div>\n
I’ve gotten contours but they’re always very off and so I’ll change something else or try another method and still they don’t seem very accurate. I’m sure I’m missing something or trying to oversimplify\/overcomplicate the process. <\/div>\n
 <\/div>\n
Please let me know if this is possible and if I need to provide any calrification. <\/div>\n
 <\/div>\n
Thank You!<\/div>\n","protected":false},"template":"","class_list":["post-290003","topic","type-topic","status-closed","hentry","topic-tag-multiphase_models-1","topic-tag-fluent"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
