Pressure Drop due to Friction
Let me Explain the conditions of problem.
Pipe Ø4mm, Air velocity 50m/s, Turbulent flow, Dy viscosity 1.79E-5 N.S/m2, Density of Air 1.23kg/m3.Need of finding the Pressure Drop for 0.1m length.
The Calculation value is 1.076kPa,but in STAR CCM+ got value as 1.255kPa.In software i specified the B.C as Inlet-Velocity inlet 50m/s and outlet-massflow outlet -7.539E-9 kg/s and mentioned Roughness Height also for account of friction factor.
In physics continuum..Constant density/Segregated flow/Steady state/K-Epsilon Turbulence.
Can u tell me what i did wrong in software? Thankyou
Is your mesh fine enough? Try to refine it and have a look what happens.
