Aerodynamics of Spheres

چکیده
Introduction This discussion is a qualitative treatment of a topic that is usually treated rigorously and quantitatively in engineering textbooks. This discussion is intended for the general audience of nonspecialists and will attempt to convey the main ideas behind aerodynamics of spheres in a qualitative manner, with a minimum number of mathematical equations. As the Latin roots of the word imply, aerodynamics deals with the dynamic flow of air (or any gas that acts like air) when in proximity to a solid body. Aerodynamics is a special subset of the more general topic of fluid dynamics. The significant distinction between air and more generic fluids is that air is a compressible fluid, whereas other fluids such as water may not be. As a compressible fluid, the density of air may vary from point to point in space as it interacts with a solid body and flows around it.

Comprehensive Investigating on the Aerodynamic Influences of the Wheel Contact Patch
Computational fluid dynamics is implemented to investigate the influence of the wheel contact patch on the global car aerodynamics. Two main aspects of the problem are the contact step and patch shape. Three important parameters: step height, cut angle, and tire tread shape are taken into consideration. For validations of the numerical results, the experimental data are also considered. The obt...
متن کاملA Numerical Study of Flow and Heat Transfer Between Two Rotating Vertically Eccentric Spheres with Time- Dependent Angular Velocities
The transient motion and the heat transfer of a viscous incompressible flow contained between two vertically eccentric spheres maintained at different temperatures and rotating about a common axis with different angular velocities is numerically considered when the angular velocities are an arbitrary functions of time. The resulting flow pattern, temperature distribution, and heat transfer char...
متن کاملHeat Transfer in a Column Packed With Spheres
The purpose of the study is to investigate average and local surface heat transfer coefficients in a cylinder packed with spheres. Here the term «local» applies to a single sphere within the bed. Averages are derived from the sixteen different spheres that were instrumented and distributed throughout the bed. The experimental technique consisted of introducing a step - wise change in the temper...
متن کاملEvaluation of the Centre Manifold Method for Limit Cycle Calculations of a Nonlinear Structural Wing
In this study the centre manifold is applied for reduction and limit cycle calculation of a highly nonlinear structural aeroelastic wing. The limit cycle is arisen from structural nonlinearity due to the large deflection of the wing. Results obtained by different orders of centre manifolds are compared with those obtained by time marching method (fourth-order Runge-Kutta method). These comparis...
متن کاملMEAN VALUE INTERPOLATION ON SPHERES
In this paper we consider multivariate Lagrange mean-value interpolation problem, where interpolation parameters are integrals over spheres. We have concentric spheres. Indeed, we consider the problem in three variables when it is not correct.
