The heat exchanger also has baffles. I am keeping the tubes at constant temperature and named them solid tubes. Also named the baffles as solid baffles which are adiabatic. In the fluent K-epsilon model is besing used. When I run the fluent, it shows &#8221; Reverse flow&#8221; in the console and all the plots become constant after some iterations. Why is this happening? Is it because of reverse flow or any other problem? How can I solve this problem?&lt;\/p&gt;&lt;p&gt;Please help me with this.
