Hi, i'm a student and i'm working on my final project about fan performance using flow simulation.
The installation of fan performance test that i made is bassed on AMCA 210 standard, my boundary condition is environmental pressure on both side (inlet & outlet)
The pressure difference in the simulation results is very small, causing a small efficiency.
Does anyone know the cause?
and why the result of motor power (power input) so far from the design power (74 W)?
please help:( your help means a lot to me
