A modification of the RANS turbulence model SSG/LRR-ωfor turbulent boundary layers in an adverse pressure gradient is presented. The modification is based on a wall law for the mean velocity, in which the log law is progressively eroded in an adverse pressure gradient and an extended wall law...
As everything related to a lens behavior, the final image lies on many factors, for example, a Perpective projection with a great Angle of View could seems more like an Orthographic projection, I mean, it's like to look to the ground from an airplane on air. From that distance, the c...
Figure6shows the 2D embedding of the airplane class, using t-SNE [37], as resulted from the triplet network. Similar viewpoints are better clustered when using our loss than when using the geometric loss of [7]. Moreover, the points are structured in a more “circular” shape, which refl...
These connections enable the flow of information between non-adjacent layers and by doing so, preserve spatial information from different scales. This idea is similar to the multi-scale approach of [9], which was shown to benefit viewpoint estimation. A concise view on the contribution of the ...
From the perspective of analyzing the aerodynamic performance of propellers according to the Reynolds number, the VLM, which is an ideal fluid-based analysis method, was considered, and the performance differences between the full and model scales were compared using the RANS simulation. The VLM is...
In Section 2, the matrix normal mixture model is explained and then the penalized matrix normal mixture model with the mean and precision matrices is introduced. Next, a new EM algorithm for the precision matrices of the proposed model, a model selection method, k-fold cross-validation, and ...
It divides the turbulence into large- and small-scales eddies by a spatially filtering function and treats the large eddies more exactly than the small ones. Many scholars, such as Dianat et al. [23] have applied LES to research fuel injection atomization and combustion. LES is the preferred...

AIR 1845—Procedure for the Calculation of Airplane noise in the Vicinity of Airports; SAE International: Warrendale, PA, USA, 2012. [Google Scholar] Moehler, U.; Kurze, U.J.; Liepert, M.; Onnich, H. The new German prediction model for railway noise “Schall 03 2006”: An alternative...
These are characterized by the propulsive system being conceived to operate in synergy with other airplane parts for an overall system-level energy benefit [1]. Consequently, the interactions between the propulsive system and its environment are enhanced and often lead to additional flow complexity, ...
