Note: The model in the example also requires the Particle Tracing Module. The effect of the blade velocity on the compression factor is shown using a Parametric Sweep. Enter the email address you signed up with and well email you a reset link. laminar flow exerts on homogeneous spherical particles with a small Reynolds number. Multiphysics Modeling USING COMSOL ® Multiphysics Modeling USING COMSOL. mechanical traps for cell pairing (Skelley, Kirak, Suh, Jaenisch. The model uses the new Rotating Frame feature, which applies centrifugal and Coriolis forces to the particles, allowing the trajectories to be computed in a noninertial frame of reference that moves with the rotating blades.

and energy transport are also an important part of the system and must be coupled or connected to the fluid-flow in some way. In this example, the trajectories of gas molecules are computed in the empty space between two rotating blades of a turbomolecular pump. The Conjugate x Domain 4 Heat Transfer-Laminar Flow Interface is used primarily to model slow-moving flow in environments where temperature Figure 5: ASC model in COMSOL. Chauveteau 1981, James and Saringer 1980) reported that, in laminar flow of. For turbomolecular pumps, in which the blades move at speeds comparable to the thermal speed of the gas molecules, a Monte Carlo approach is needed. attempt to understand the mechanism of polymer-induced drag reduction.

The Free Molecular Flow interface available in the Molecular Flow Module is an efficient tool for modeling extremely rarefied gases when the gas molecules move much faster than any geometric entities in the domain. Laminar Flow: Time Dependent VS Stationary. I have imported the geometry (attached) of twin screw to COMSOL and created an air domain around it using box geometry. Number density (1/m 3) inside a vacuum chamber fed with a small capillary tube, modeled using half the geometry with a Plane Symmetry.Īpplication Library path for an example that uses the Plane Symmetry boundary condition: Molecular_Flow_Module/Industrial_Applications/differential_pumping New Tutorial: Turbomolecular Pump I am using rotating machinery, laminar flow physics.
