摘要:Abstract(#br)Swept wing is widely used in civil aircraft, whose airfoil is chosen, designed and optimized to increase the cruise speed and decrease the drag coefficient. The parameters of swept wing, such as sweep angle and angle of attack, are determined according to the cruis...

摘要:Abstract(#br)In the estimation of momentum fluxes over land surfaces by the bulk aerodynamic method, no unique value of the drag coefficient ( C D ) is found in the literature. The drag coefficient is generally estimated from special observations at different parts of the worl...

摘要:... A special attention is paid to compute the drag and lift forces acting on the rectangular shapes, which allowed determining the best shapes configuration in terms of both drag and lift. The unsteady periodic wake is characterized by the Strouhal number, which varies with the ...

摘要:Abstract(#br)Using MONTBLEX-90 mean velocity data, roughness lengths and drag coefficients are estimated at Jodhpur and Kharagpur. At Jodhpur, since the surface is not uniform the roughness length is estimated separately in three different subsectors within the range of prev...

摘要:Abstract(#br)The drag coefficient of a spherical particle translating in a viscoelastic matrix is affected by the viscoelasticity of the fluid. In many computational modeling for large industrial applications, where the ensemble-averaged behavior of the mixture is of most inter...

摘要:Abstract(#br)The detailed numerical simulation of the unsteady drag coefficient of deformable droplet is investigated with a mass conserving level set (LS) method. The simulation results indicate that the unsteady drag coefficient is always larger than the steady standard drag coefficient...

摘要:Abstract(#br)We seek to determine whether a small number of measurements of upper ocean temperature and currents can be used to make estimates of the drag coefficient that have a smaller range of uncertainty than previously found. We adopt a numerical approach in an inverse probl...

摘要:Drag coefficient has been commonly used as a quantifying parameter to represent the vegetative drag, i.e., resistance to the flow by vegetation. In this study, the measured data on the drag coefficient for rigid vegetation in subcritical open-channel flow reported in previous...

摘要:The \(^{3}\) He impurity influence on the oscillations of a quartz resonator and thus its drag coefficient in a laminar flow of a superfluid \(^{3}\) He– \(^{4}\) He mixture has been investigated. The temperature dependences of the resonance curves were measured on quartz tun...
