A Semi-empirical Model to Predict the Attached Axisymmetric Shock Shape
In this work, a simple semi-empirical model is proposed, based on Response Surface Model, RSM, to determine the shape of an attached oblique shock wave emanating from a pointed axisymmetric nose at zero angle of attack. Extensive supersonic visualization images have been compiled from various nose shapes at different Mach numbers, along with some others performed by the author for the present p...

Using Neural Networks to Predict Aircraft Trajectories
This paper deals with the problem of predicting an aircraft trajectory in the vertical plane. A method depending on a small number of starting parameters is introduced and then used on a wide range of cases. The chosen method is based on neural networks. Neural networks are trained using a set of real trajectories and then used to forecast new ones. Two prediction methods have been developed: t...
متن کاملComputation of hypersonic shock boundary layer interaction on a double wedge using a differential Reynolds Stress Model
The simulation of hypersonic flows presents some difficulties due to the interaction between boundary layers and shock waves and to the high total enthalpy. In order to achieve more accurate numerical results with respect to physics, a Reynolds stress model (RSM) has been implemented in the well validated Reynolds averaged Navier-Stokes solver QUADFLOW. The RSM developed and tested by Eisfeld, ...
متن کاملReynolds stress and the physics of turbulent momentum transport
The nature of the momentum transport processes responsible for the Reynolds shear stress is investigated using several ensembles of fluid particle paths obtained from a direct numerical simulation of turbulent channel flow. It is found that the Reynolds stress can be viewed as arising from two fundamentally different mechanisms. The more significant entails transport in the manner described by ...
