A Difference Scheme with Autocontrol Artificial Viscosity to Predict Ablated Nosetip Shape

Abstract

The trio-layer explicit difference scheme which is added artificial viscosity item is found by using filteration in the computation of ablated nosetip shape. The scheme is of first order accuracy in regions where shape change is wavy and second order accuracy in regions where is Smooth. Numerical experiments show that the scheme developed is effective.
