Application of dynamic weighting in HVD coordinate integrated algorithm;

A Self-Adaptive Image Fusion Method Based on Dynamic Weighting of Regional Features;

In this paper,a multi factor dynamic weighting method of threatening estimation is put forward on the bases of analysing former threatening estimation methods for drawback.

To solve this problem,the basic methods of generating dynamic grids were introduced firstly,then the dynamic layering method was used to generate the dynamic grids,with which the inner flow field of solid rocket motor was calculated.

According to propagation principle of surge wave,a new characteristics method based on dynamic grids is proposed in the paper,which can simulate and calculate hydraulic transient effectively in batching transportation.

In order to solve the problems that data input reliance and the clustering result was not efficient in overlapping grids partition technique,this paper proposed a dynamic grids clustering algorithm based on overlapping partition(DGBO).

2D unstructured dynamic mesh research on store separation;

To study the flow characteristics and obstacles effects on the closure of rotary valve,the numerical simulation about the process of a rotary-valved PDE unsteady inlet flow is made with the technology of dynamic mesh.

The dynamic mesh deformation method based on Delaunay graph mapping is non-iterative and is therefore efficient for unsteady flow solutions.

Based upon the moving grids and embedded grids, a moving embedded grid system is established to consider actual blade flapping and pitching motions.
