Abstract For a good functioning of the activities carried out within research institutions both at managerial level and for fulfilling technical requirements, we aim to determine aerodynamic characteristics standard profiles used in aerospace field by testing subsonic tunnel. We also intend conduct study based on numerous experimental tests performed wind tunnels that can be compared actual sca...

A rectangular wing with Wavy Leading Edge (WLE) effect was investigated experimentally and numerically. This research carried out the NACA 0018 profile. The morphology of humpback whale flippers, which are blunt rounded in a specific pattern, inspired design WLE. explored pitching motion reduced frequency k = 0.25 varied aspect ratios. Multiple ratios (AR) have been evaluated to determine best ...

It is generally assumed that hashing is essential to solve many language processing problems efficiently; e.g., symbol table formation and maintenance, grammar manipulation, basic block optimization, and global optimization. This paper questions this assumption, and initiates development of an efficient alternative compiler methodology without hashing or sorting. The methodology rests on effici...

The main aim of this article is to present two new ways solve the elliptic obstacle problem by using discontinuous Galerkin finite element methods. In Gaddam and Gudi (Comput Methods Appl Math 18:223–236, 2018. https://doi.org/10.1515/cmam-2017-0018 ), a bubble enriched conforming quadratic method introduced analyzed for in dimension 3. article, without adding functions, we derive optimal order...
