TsAGI Takes Part in 17th International Heat, Mass Transfer Forum

6 June 2024

Development of aviation industry requires solving a great number of fundamental issues, such as turbulence. Eliminating the danger of turbulence can allow for better aircraft designs, for instance, in terms of cost efficiency. TsAGI (a part of NRC “Zhukovsky Institute”) presented its research results at the 17th International Heat and Mass Transfer Forum, which took place late May in Minsk, Belarus.

Ivan Yegorov, Chief Researcher for Aerohydrodynamics at TsAGI and Corresponding Member of the RAS, presented his report, Numerical simulation of the interaction of a Mach wave and a boundary layer on a flat plate.

‘Turbulence and its generation are a relevant problem. Analyzing the reasons of turbulence generation can allow for controlling turbulence. More cost-effective aircraft can be created with reliable tools that would shift boundary layer downstream and provide air-sweeping of most wing area with laminar boundary layer. And the costefficiency can be as much as 30%,’ said Ivan Yegorov.

The scientist spoke on the possibilities of controlling aircraft flow and showed results of numerical modeling of interaction between weak impact wave and laminar boundary layer on a flat plate. The plate is the simplest model of an aircraft’s unit, and is widely used in fundamental research.

Direct numerical simulation method used by TsAGI solves three-dimensional unsteady Navier-Stokes equations. All stages of laminar-turbulent transition are analyzed, from small disturbances coming to boundary layer, including receptivity stage, to the turbulence. Direct numerical simulation gives an understanding of key principles of this phenomenon.

The Forum is organized by A.V. Luikov Heat and Mass Transfer Institute of the National Academy of Sciences of Belarus. It focuses on convective and radiative heat transfer, heat and mass transfer in phase and chemical transformations, heat and mass transfer in energy and technological processes, thermophysical properties of substances and materials, thermal and transport processes in nanostructured and microstructured systems, high-temperature heat and mass transfer, plasma systems and technologies, modeling and controlling heat and mass transferring. This year’s Forum gathered over 200 specialists from Russia, Belarus, Kazakhstan and other countries, who presented more than 300 reports.
