A Novel Method for CSAR Multi-Focus Image Fusion

Circular synthetic aperture radar (CSAR) has attracted a lot of interest, recently, for its excellent performance in civilian and military applications.However, in CSAR imaging, the result is to be defocused when the height of an object deviates from a reference height.Existing approaches for this problem rely on digital elevation models (DEMs) for

The effects of flame orientation and mean shear on flame stretch in highly turbulent premixed flames using DNS

In the present work, direct numerical simulation data of a laboratory-scale high Karlovitz number (Ka) jet flame with a strong mean shear and a high Ka freely propagating planar flame without a mean shear were analyzed to explore the influence of flame orientation and mean shear on flame stretch in highly turbulent flames.Three flame fronts, i.e.th
