Yes, I am using the Fluent expression and I also check the units. Now, I am simulating the air conditioning of nose in respiratory. So, there is a inspiration and respiration. I use the pressure inlet and mass flow outlet as my boundary condition and I set the sinusoidal mass flow rate...
Hi everyone. Its mentioned in the Ansys Fluent manual that I should not use outflow boundary condition especially in a multiphase flow. I am using a mass flow inlet and pressure outlet boundary condition. I am running with 1.6 million cells and I am alre
The evolution of inlet pressure is obtained by another transient case in FLUENT, where the 42-channels domain is modeled and inlet velocity is set as 5.457kg/s according to the design condition. Although it is convenient for RELAP code to simulate this progress, empirical formulas of local ...

NUMERICAL STUDIES ON VARIATION OF PRESSURE AND VELOCITY AT INLET AND EXHAUST OF A TURBOJET ENGINE WITH FLUENT SOFTWAREIn the present study, the flow analysis of various parameters such as static pressure, velocity, total temperature, along inlet and exhaust passages of the turbojet engine has ...
3c); this solution is adopted in order to keep the flow at the inlet boundary perpendicular to the boundary itself, since the vortex method is used as inflow generator for LES. As a matter of fact, in ANSYS Fluent [61] the VM does not provide accurate turbulence generation when oblique ...
I am trying to set a pressure inlet boundary condition in Fluent 6.1 I want to specify the static pressure at the inlet of the pipe. But Fluent only asks for the Total Pressure at inlet boundary. As soon as I run my pipe flow problem some dynamic pressure is developed and it reduces ...
My problem is the supersonic gauge pressure. The boundary described, is that the inlet boundary or the boundary where the flow becomes supersonic? If it is the latter, I fail to see from where I should know this information. It is this answer I am seeking to calculate using Fluent, not...
