| 内容記述 | The discrete vortex method was applied to the calculation of the separated flow around aerofoils. A new approach was formulated, in which the strength of the vortex, which is shed off at the separation point, was included in the unknown variables. In order to save computational cost, simplifications were introduced in the formulation; e. g., clusters of the drifting vortices were treated as concentrated single vortices. Because the total pressure in the separated region is less than that in the other region, the pressure distribution around the aerofoil, which is obtained from the velocity distribution through the Bernoulli formula, has to be evaluated individually for the non-separated and separated regions. To define the relativity between the two pressure distributions, a method of estimating the amount of the total pressure loss in the sepa-rated region was introduced. The Blasius formula, which is generally used to derive the forces acting on an obstacle, was modificd to include the influence of the total pressure loss upon the lift and the drag forces. | |||||||||
