Fast transonic flow prediction enables efficient aerodynamic design
The Physics of Fluids, 2023A deep learning framework is proposed for real-time transonic flow prediction. To capture the complex shock discontinuityof transonic flow, we introduce the residual network ResNet and deconvolutional neural networks to learn thenonlinear discontinuity ...

Flow in Transonic Compressors [PDF]
AIAA Journal, 1980 Introduction B the term transonic compressor we mean an axial flow compressor in which the inlet flow Mach number, relative to the rotating blades, varies from below unity at radii near the inner casing or hub to values substantially above unity at radii near the blade tips.

Summary: The structure of the flowfield in the vicinity of the trailing edge of a flat plane at zero incidence in mixed transonic flow has been studied using viscous-inviscid interaction methods. The resulting nonlinear partial differential equations governing the flow were solved numerically using finite-difference methods for a range of values of a ...

We are concerned with geometric properties of transonic shocks as free boundaries in two-dimensional self-similar coordinates for compressible fluid flows, which are not only important for the understanding of geometric structure and stability of fluid ...

Steady and unsteady transonic flow
16th Aerospace Sciences Meeting, 1978An investigation of the transonic flow over a circular arc airfoil was conducted to obtain basic information for turbulence modeling of shock-induced separated flows and to verify numerical computer codes which are being developed to simulate such flows. The investigation included the employment of a laser velocimeter to obtain data concerning the mean

Perturbation of a discontinuous transonic flow
15th Aerospace Sciences Meeting, 1977The main difficulty in perturbing a discontinuous transonic flow is in the representation of the shift in the location of the discontinuity (shock wave). Herein presented is a method of overcoming this difficulty by using a distorted airfoil as the initial case rather than the real physical airfoil; the distortion is chosen such that the shock location

Transonic flow in unconventional nozzles.
AIAA Journal, 1968The description of the compressible gas flow in the throat region of unconventional rocket nozzles must be known in order to optimize the wall contours and to predict the performance. The existence of both subsonic and supersonic flow in close proximity does not permit the use of conventional analytical techniques to obtain a mathematical description ...
