Numerical study of the aerodynamic characteristics of an axisymmetric profile of an optimized shape

Abstract

Today, one of the important and urgent tasks of the aerodynamics science is the study and op-timization of aerodynamic characteristics of optimized profile shapes in a gas flow. This problem arises in the design of aircraft and various vessels and is associated with a rational choice of profile shape for a large number of different characteristics and, in particular, in terms of aerodynamic drag. In this paper, consider methods for optimizing an axisymmetric aerodynamic profile in a sta-tionary laminar inviscid gas flow at different angles of attack. The proposed method of solv-ing such a problem of optimization and numerical study of aerodynamic characteristics of the described body in the flow is relevant due to the complexity of its solution, for example, by traditional methods based on the Navier-Stokes system of differential equations. Experi-mental methods are based on expensive and time-consuming tools that do not guarantee find-ing the optimum. Such a computing tool as Ansys Fluent is well suited for solving such prob-lems of hydroaerodynamics and allows not only to speed up and reduce the cost of the compu-tational experiment, but also to increase the efficiency of its implementation. The article describes the process of finding the optimum, which reduces to minimizing the drag force of the previously described axisymmetric profile. A description is also given of the wing
