When modelling wheels in CFD there are two main challenges, replicating the geometry and ap- plying representative boundary conditions. The focus of this work will be the boundary conditions.

Mar 1, 2018 · This section describes the numerical approach used to simulate the rotation of tyres. Most Computational Fluid Dynamics (CFD) codes offer different numerical approaches to describe models with rotational parts: Rotating Wall (RW), Moving Reference Frame (MRF) and Sliding Mesh (SM).

Nov 3, 2019 · This tutorial video shows the correct way of modelling a wheel in rotational motion for CFD analysis. The wheel geometry file for the tutorial can be found h...

Nov 1, 2019 · The present paper aims at defining a framework for CFD simulations of an isolated spoked wheel by a systematic sensitivity analysis focused on the computational grid, wheel rotation modeling and turbulence modeling.

Apr 3, 2018 · Wheel Aerodynamics is an important part of vehicle aerodynamics. The wheels can notably influence the total aerodynamic drag, lift and ventilation drag of vehicles. In order to simulate the real on-road condition of driving cars, the moving ground and wheel rotation is of major importance in CFD.

Nov 1, 2020 · 37 CFD simulations are performed on a cycling spoked wheel. • CFD results are validated with respect to WT results available in literature. • CFD shows significant blockage effect in WT tests even at very low BRs. • CFD guidelines for wheel/ground contact modeling in crosswind conditions. •

In the present study, a detailed experimental validation is conducted to verify, evaluate and validate the previously identified rotational speed induced effects and the developed enhanced modelling approach.

By investigating six different wheels with varying rim profiles, depths and spoke counts, combined with upstream flow angles varying between 0° and 30°, this study should show if CFD is a valid tool to develop aerodynamic bicycle wheels.

however, the complex nature of rotating spoked wheels requires high resolution meshes to model at acceptable fidelity. This research investigates an alternative CFD method that lowers the computational cost of modeling aerodynamic bicycle wheels by modeling spokes using Blade Element Method (BEM).

May 23, 2019 · Vdovin et al. 18 present a simulation study on the ventilation resistance moment of a wheel and factors that affect it using computational fluid dynamic (CFD) methods.
