DEVELOPMENT OF A TECHNOLOGY FOR COUPLED CALCULATIONS OF THE DYNAMICS OF A BODY PERFORMING WAVE OSCILLATIONS AND HYDRODYNAMICS OF A FLUID FLOWING AROUND IT
This article presents the development of a calculation methodology for a class of problems where the movement of a body is caused by a largescale deformation of the shape of the body itself, in particular, a wing flap type deformation. The approbation of this technology takes place on the task of flying a mosquito in a stationary environment. The parameters of the problem, the shape of the vibrations and the deformation of the wing are taken based on the article [3]. The calculation method involves the joint solution of the equations of the dynamics of the body and the equations of the hydrodynamics of the fluid flowing around it. For this task, an original mesh deformation algorithm was developed that allows hydrodynamic calculations to be performed near the wings of the model performing flapping and bending vibrations. The use of deformable mesh technology allows you to reproduce the shape of vibrations as accurately as possible. In addition, the calculation scheme has the property of conservativeness, which makes it possible to obtain high quality calculations, confirmed by comparison with experimental data.
