A blended drag coefficient model is constructed using a series of empirical relations based on Reynolds number, Mach number, and Knudsen number. When validated against experiments, the drag coefficient model produces matching values with a standard deviation error of 2.84% and a maximum error of ...
Drag coefficient calculations using the Cercignani–Lampis–Lord quasi-specular gas–surface interaction model have been used to derive modified closed-form solutions for several simple geometries. The key component of the modified closed-form solutions is a relation between the normal energy and normal...
Drag coefficient (Cd) is an essential metric in the calculation of momentum exchange over the air-sea interface and thus has large impacts on the simulation or forecast of the upper ocean state associated with sea surface winds such as storm surges. Generally,Cdis a function of wind speed. H...

Model S is built for speed and range, with beyond ludicrous acceleration, unparalleled performance and a refined design.
Using software FLUENT in the RNG κ-ε turbulence model with Reynolds number 20000 and spacing ratio s/d equaling to 1.75,this article simulates two cylinders' drag and lift coefficients in four engineering conditions,as the two cylinders are set in serial,in parallel,as well as there are an...
Besides, the particle's drag force is proportional to the projected area of the particle in its direction of motion. Therefore, it is important to include the effect of settling orientation into the drag coefficient and settling velocity model to better describe the settling behavior of non-...
Atmospheric boundary layer structure and drag coefficients over sea ice This paper estimates the air/sea drag coefficient for first-year ice from recent aircraft measurements and reconciles the range of observed drag coefficients (103CD = 1.2–3.7 referenced to 10 m) for all sea ice types, ...
drag coefficient with k-eps model #1 Mark Guest Posts: n/a Hi, I'm calculating the 2D-flow over a NACA0015 profil with standard k-eps turbulence model. yplus values are between 20 and 100 along the chord. I'm am looking for an explanation for the following observation. ...
