Jesko Absolut | Koenigsegg Automotive AB How to estimate a constant drag coefficient of a boat? Numerical investigations of the flow-induced vibration of a three ... This difference in the drag coefficient was due to end flow effects for the test points shown. To do so, I need to include a constant drag coefficient without knowing the drag force and velocity (both will be estimated after the resistance analysis). In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. The drag coefficient is a dimensionless number that depends on the shape of the object. A sensitivity experiment demonstrates the significant effects of sea-ice form drag included by an improved parameterization of the transfer coefficients for momentum and heat over sea ice. Nissan This has been well studied for round bodies like spheres and cylinders.The drag coefficient of a sphere will change rapidly from about 0.5 to 0.2 at a Reynolds number in the range of 300000. Labraga et al. drag coefficient In [16], the problem of the cylinder vortex resistance was considered and the drag coefficient was obtained, l … Flow Measurement and Instrumentation, Vol. Note that this definition replaces the F_D/d^2 present in the definition of the usual drag coefficient with f_d/d.
