Using SolidWorks Flow Simulation to Determine Which Fan Blade is Better

Using SolidWorks Flow Simulation to Determine Which Fan Blade is Better

Using SolidWorks Flow Simulation to Determine Which Fan Blade is Better

(OP)
Hey Everybody,

I am using SolidWorks Flow Simulation to look at the internal flow of air passing through a tube. Inside the tube is a small fan blade (approximate .700" OD). I am simulating the fan blade running at 2000 RPM.

I have several versions of the fan blade, and I am trying to figure out which "metric" to use to make an apples-to-apples comparison between the 4 different fan blades that I have designed.

I do not see MASS FLOW RATE as one of the options for simulation results. MASS FLOW RATE is however one of my goals for simulation convergence. When I look at the GOAL PLOT, the MASS FLOW RATE is positive and negative...like a transient response...until the MASS FLOW RATE converges. Is the converged value for MASS FLOW RATE the number that I should be looking at?

I thought that I would have to somehow integrate the velocity over the cross-sectional area and then multiply by the density (assuming constant density for air for simplification).

TIA,
--Neal
