Noun1.drag coefficient- the ratio of the drag on a body moving through air to the product of the velocity and the surface area of the body coefficient of drag coefficient- a constant number that serves as a measure of some property or characteristic ...
DRAG coefficientFLOW simulationsA passive method for reducing the drag of a cylinder by placing a flat plate behind it at a Reynolds number Re=105 has been studied. The paper presents the results of an ANSYS Fluent simulation of the flow around a cylinder–plate system, ...
1) drag-coefficient 拉力系数1. We study adaptive computation of drag-coefficient of flow around a cylinder. 研究圆柱绕流中拉力系数的自适应计算问题。更多例句>> 2) restrictive coefficient of tension stress in concrete 拉应力限制系数 1. Results of the test and theoretical researches are introduced...
solid cylinder, and solid square rod have drag coefficients that are functions of the shape's dimensions. Blevins (2003) provides tables of the drag coefficient versus dimensions. LMNO Engineering has fit equations to the Blevins tabular data with the resulting drag coefficient shown in the calculat...

The drag coefficient of a cylinder was calculated from data obtained by performing tests in an air flow bench (AF12) with varying flow velocities and diameters as 12.5mm, 15 mm, 20 mm, and 25 mm. To obtain the values of co-efficient of drag, two methods: (i) direct weighing method,...
As η is the empirical coefficient that account for the variations in the in-line motion of the cylinder in Eq. (23), we established that η=0.5 will be used for this set of small gap ratios. This value was established because for all large and medium gap ratios simulated: 0.65≤η...
Hi, i have a probleme with the drag's coefficient. I am with a 2-D axissymetric problem for a flow over a modified cylinder (a rocket). L=10m , D=0.5m and Mach=1.3 It seems that the probleme is the "reference value". I don't know the right value for the "Area" and the "...
acquired conclusions are as follows: The drag coefficient increases with the increasing angles,which reaches maxim when the cylinders are in parallel,while it is minus with the cylinders in serial;as to the lift coefficient,the integral is not equal to 0 besides the two cylinders are in serial...
