Abstract
Study on the calculation method of wind forces on a 2-dimensional body is made to propose a more reasonable one in theoretical treatment, based on the Discrete Vortex Method (DVM) which is considered to be useful in calculation because of its simplicity. The general theory based on a Fredholm type integral equation of the 2nd kind is introduced into the problem, in which the unknows of both vortex and source distributions on the body surface are signified simunltaneously, and this problem leads to the so-called well-posed problem differing from the usual DVM. Furthermore, another calculation method of the pressure distribution on the body surface is proposed considering with the unsteadiness of vortex shedding. Numerical calculations are carried out for simple cases and compared with the experimental data in order to confirm validity of this method.
