Hello! <\/p>\n

I’m simulating a laminar flow crossing a device in different cases (with modifications of its internal geometry). <\/p>\n

In case of a widening of the ducts of the internal geometry, the average velocity tends to decrease (It has sense because the diameters of the ducts are bigger). But the average pressure results show also the pressure tends to decrease and I don’t know if it has sense, considering the pressure should increase with the widening of the ducts… The boundary condictions are: inlet velocity>0; inlet pressure=0; outlet pressure=0, for all cases.<\/p>\n

My question is: what type of pressure measure Fluent? and, has it sense the pressure and the velocity decrease at the same time?<\/p>\n

In a third case, with already bigger ducts, the effect is the same: average velocity and also pressure of the flow decrease…<\/p>\n

Here is the system schematically:<\/p>\n

<\/p>\n

Thank you in advaced.<\/p>\n","protected":false},"template":"","class_list":["post-367058","topic","type-topic","status-closed","hentry"],"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\n\t\t\n\t\t\n\t\t
