A synoptic parameterization of the drag coefficient [PDF]

Atmosphere, 1974
Abstract The frictional force exerted on the atmosphere over Lake Erie is investigated by incorporating synoptic weather data into boundary layer theory. Over‐water data obtained during a severe winter storm by the ccgs N.B. McLean on Lake Erie are used. The friction force is a function of the drag coefficient Cd .

Computation of drag and diffusion coefficient for coronavirus: I

Journal of Aerosol Science, 2021
Monte Carlo simulations and integral equation techniques allow for the flexible and efficient computation of drag and diffusion coefficients for virus mimetic particles. We highlight a Monte Carlo method that is useful for computing the drag on biomimetic particles in the free-molecular regime and a numerical technique to solve a boundary integral ...

Superhydrophobic surfaces on supercritical airfoils: mitigating ice formation and enhancing performance

International Journal of Thermofluids
Superhydrophobic surfaces are characterized by low surface energy and micro- to nano-scale roughness. These properties cause fluids to slide over the surface, thereby reducing drag and adhesion, and resulting in a lower drag coefficient.
