WebNext, we apply the two pseudo-spectral methods to solve the nearly singular solution of the 3D incompress-ible Euler equations. We would like to see if the comparison we make regarding the convergence properties of the two pseudo-spectral methods for the 1D Burgers equation is still valid for the more challenging 3D incom-pressible Euler equations.

The pseudospectral method: Accurate representation of …
WebApr 11, 2024 · The spectral adjustment factors (SAF) were derived from the solar spectrum measured by the sensor to minimize the uncertainties caused by the different spectral response functions (SRF) of sensors. In addition, a correction method based on the radiative transfer model (RTM) SCIATRAN was used to suppress unaccounted angular dependence … WebPartial differential equations arise in almost all areas of science, engineering, modeling, and forecasting. During the last two decades pseudospectral methods have emerged as … WebThe results demonstrate that the speed of convergence for this method is O ( 2 − J ) where J ∈ N 0. One of the advantages of the method is that it is not too complicated in form, and it can be used to solve a variety of problems. Furthermore, the method is computationally desirable and gives very accurate results. flash help player
