Extending the outlet will prevent fluid from trying to re-enter at this boundary.&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span lang=&#8221;EN-US&#8221; style=&#8221;mso-ansi-language: EN-US;&#8221;&gt;You wrote that you have a nanofluid in this heat exchanger. Is the second phase that you are trying to model the nanoparticles? If so, what are your problem dimensions? Typically, when we model nanofluids we will adjust the fluid properties of a single phase simulation. Modeling the particles themselves is a computationally intensive problem and done only for very simple geometries. Your HEx looks a bit more complex than what is typically considered.&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span lang=&#8221;EN-US&#8221; style=&#8221;mso-ansi-language: EN-US;&#8221;&gt;Yes look at the velocity vectors and temperature contours at the exit. It would also be good to look closely at the condition you defined at the outlet. When the solution builds a wall at the outlet it can lead to the convergence not being good, especially if the mesh is coarse.&nbsp;&lt;\/span&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-374818","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Yes with the multiphase model the outlet boundary condition is more complex.
