Scientists at the Research Institute of Mechanics of Moscow State University have developed a method that allows for more accurate calculation of thermal processes in supersonic flows. This discovery could radically improve the efficiency and reliability of future gas turbine engines and power plants.
The main feature of the new method is the ability to predict in more detail how parts inside the engine heat up and cool down as hot gas passes through them.
Previously, such calculations were based on simplified models that did not take into account the influence of flow compressibility, pressure gradients, and boundary layer behavior.
Now, engineers will be able to take into account key parameters, which is especially important when designing digital twins and test prototypes, where the accuracy of the simulation directly affects the reliability of the real machine.
The work was carried out on the AR-3 supersonic stand under the guidance of senior researcher Nikolai Kiselev. The researchers used infrared thermography and numerical modeling using the Navier-Stokes equations to determine how thermal processes change at different speeds and pressures-from subsonic to hypersonic regimes.
Earlierwww1.ru reported that the legendary Tu-134 will receive an unexpected purpose in the Moscow region.
