报告摘要:The development of rotor aerodynamics (screw propeller,propeller, wind turbine, helicopter, etc.) has always been associated with anintensive development of the appropriate branch of industry. The first attemptconcerning the steamship navigation using screw propellers should results tothe one-dimensional momentum theory of the screw propeller, called also theone-dimensional slim-stream or actuator disc theory by Rankine and Froude. Thesecond era in the development, made by the scientific schools of Joukowsky andPrandtl, was motivated by creation and intensive evolution of aviation. At thattime the researches resulted in a development of the blade element momentum(BEM) theory to design rotor blades; in a creation of the general momentumtheory of the actuator disc and in a formulation of a new vortex concept ofrotor. The current development of the rotor aerodynamics is undoubtedlyassociated with the rapid progress of wind energy.
报告人简介:
Prof. Valery Okulovworks in DTU, Denmark more than 10 years but before that he worked long time inInstitute of Thermophysics, SB RAS, Russia. He obtained his degrees of D.Sc.(1994) and PhD (1985) in Fluid Dynamics. His research area is focused onaerodynamic and acoustic of turbo machines and wind turbines; hydrodynamics andphysical processes in swirl flows; vortex dynamic, resonances and hydrodynamicsinstability in power-engineering devices. His scientific works are awardeddiplomas and prizes: JSPS invitation fellowships (Japan), Diploma of TsAGI,Medal of G.I. Petrov for outstanding results in hydrodynamical stability andturbulence, Diploma of the Russian Academy of Sciences for outstandingscientific results, Otto Mønsted professorships (Denmark), Fellowship for youngD.Sc. granted by the President of the Russian Federation etc.
