Aerodynamic effect of bicycle wheel cladding: A CFD study

Arora, B. B.; Bhattacharjee, Sourajit; Kashyap, Vishesh; … - In: Energy Reports 5 (2019), pp. 1626-1637

Aerodynamic drag in a bicycle can originate through the rotation of wheels, and the addition of cladding on the wheels … has a pronounced impact on the same. In the present work, the effect of cladding on the wheels of a bicycle is studied in … terms of the percentage cladding in order to predict the aerodynamic drag using a validated CFD model. SolidWorks Flow …

Kinetic theory of drag on objects in nearly free molecular flow

Sengers, J.V.; Lin Wang, Y.-Y.; Kamgar-Parsi, B.; … - In: Physica A: Statistical Mechanics and its Applications 413 (2014) C, pp. 409-425

Using an analogy between the density expansion of the transport coefficients of moderately dense gases and the inverse-Knudsen-number expansion of the drag on objects in nearly free molecular flows, we formulate the collision integrals that determine the first correction term to the...

The modeling of colloidal fluids by the real-coded lattice gas

Sakazaki, Y.; Masuda, S.; Onishi, J.; Chen, Y.; Ohashi, H. - In: Mathematics and Computers in Simulation (MATCOM) 72 (2006) 2, pp. 184-189

We model colloid-dispersed fluids using the real-coded lattice gas, in which colloidal particles are treated as hard spheres interacting with solvents of the lattice gas particles. We simulate the Brownian motion of a colloidal particle and compare its velocity distribution with that from the...

On the influence of changes in the drag relation on surface wind speeds and storm surge forecasts

Zweers, N.; Makin, V.; Vries, J.; Burgers, G. - In: Natural Hazards 62 (2012) 2, pp. 207-219

In this study it is investigated how uncertainties in the magnitude of the drag coefficient translate into uncertainties in storm surge forecasts in the case of severe weather. A storm surge model is used with wind stress data from a numerical weather prediction (NWP) model, to simulate several...
