The individual chapters reflect ongoing research conducted by the STAB members in the field of numerical and experimental fluid mechanics and aerodynamics, mainly for (but not limited to) aerospace applications, and cover both nationally and EC-funded projects. Special emphasis is given to collaborative research projects conducted by German scientists and engineers from universities, research-establishments and industries. By addressing a number of cutting-edge applications, together with the relevant physical and mathematics fundamentals, the book provides readers with a comprehensive overview of the current research work in the field. Though the book's primary emphasis is on the aerospace context, it also addresses further important applications, e.g. in ground transportation and energy Notes ""3.2 Effects of the Length Scale Equation on History Effects"" Includes author index Print version record Subject Aerodynamics -- Congresses Airplanes -- Design and construction -- Congresses Fluid dynamics -- Congresses Turbulence -- Congresses TECHNOLOGY & ENGINEERING -- Engineering (General) TECHNOLOGY & ENGINEERING -- Reference.
