Request: Flow Around a Cylinder · 模型 181988
Complete with a SolidWorks animation (CFD). FEA not accurate, I think at the wind speed I applied in the CFD, the cylinder will blow away from the rack, Simulation Premium was giving an error that the model is not stable, so I added extra fixtures. Vertical Force: 0.845 N (Y-axis) Horizontal Force: -0.599 N (Z-axis) Animation here: http://www.dailymotion.com/video/x2kl2s2_solidworks-animation-flow-around-a-cylinder_tech Re = (ρ∞ * V∞ * D)/ μ∞ = (1.177 * 2.778 * 0.3048) / (1.846 * 10-5) = 53987.35 ρ∞ = kg/m3 = Dry air's density at 300 K V∞ = m/s = Velocity of stream (dry air) D = m = Diameter of cylinder (replacement for chord length) μ∞ = kg/m * s = Dry air's dynamic viscosity at 300 K Cd = D / (q∞ * S) = 0.599 / (4.541 * 0.584) = 0.226 D = 0.599 N (From SolidWorks Flow Simulation*) q∞ = ½ * ρ∞ * V∞2 = 0.5 * 1.177 * 7.716 = 4.541 Pa S = π * d * h = 3.142 * 0.3048 * 0.6096 = 0.584 m2 Cd = Drag Co-efficient D = Drag Force (*Mesh level I guess was 6 in Flow Simulation, no adaptive Mesh) q∞ = Dynamic pressure = Pa S = Surface area of cylinder = m2 d = Diameter of cylinder = m h = Length of cylinder = m
