Respected!<\/div>\n
I am new to using Ansys fluent. I am combustion and use heat of combustion to boil water.<\/div>\n
\"\"<\/div>\n
I have achieved combustion using species transport model. But my problem is with Multiphase model. I have define 3 phases, phase 1; water liquid, phase 2; water vapour and phase 3; combustion species. <\/div>\n
\"\"<\/div>\n
There is no interaction between phase 1 and 2 to phase 3. I can’t remove the interfacial area between phase 3 and phase 1 in phase interaction of multiphase model.<\/div>\n
\"\"<\/div>\n
I have set none for virtual mass, drag, lift, wall lubrication, turbulence dissipation, turbulence interaction, heat and surface tension between phase 3 and phase 1 and 2. I have use single mechansim of mass transfer from water liquid to vapour.<\/div>\n
\"\" <\/div>\n
I have used 0 reactions in reaction option as I have select methane air two step reaction using species transport. <\/div>\n
\"\"<\/div>\n
My question is: As there no interaction between phase 1 and 2 to phase 3 but multiphase model shows that there is interaction in all three phases?<\/div>\n
My second question: Is there is a way to extract heat flux or temperature on surface and use separate fluent model for phase change of liquid water to vapour and how can I achieve it?<\/div>\n
