The Japan Society for Aeronautical and Space Sciences : Japan Aerospace Exploration Agency (JAXA), Online meeting), The variational principle of the Stokes equations for low Reynolds number flow, and its relation to the drag force acting on a body immersed in fluid are discussed. The steady Stokes equations are known to be derived by minimizing the integral of the dissipation over the whole flow domain under the constraint of the equation of continuity. Considering the uniform flow at the outer boundary and the no-slip condition on the body surface, it is shown that the minimization of the dissipation is equivalent to that of the drag force acting on the body. Consequently, the drag force in the Stokes flow is smaller than that acting in the flow governed by the Navier-Stokes equations. To check the validity of the above theory, the numerical simulation was conducted by varying the Reynolds numbers., 形態: 図版あり, Physical characteristics: Original contains illustrations, 資料番号: AA2030013011, レポート番号: JAXA-SP-20-008},
