“…In reality, the users need to repeat the grid movement computations and procedures many times during their simulation steps, which may take a long time to be fulfilled [1,5,12,13,15,19,24,28,29,31,33,39,43,44,51]. Therefore, the current achieved performances are much higher in real practical problems, where grid computations are very heavy and may need several hours of computations.…”

“…There are many fluid flow simulations, such as the aerodynamics shape optimization [1,13], fluid-structure interaction [24,43], store separation [15,19], moving objects [31,44], and free surface flows [12,28], in which the grid movement is mandatory. In such fluid flow simulations, the computational domain should be suitably moved to account for the deformation occurred at its boundaries.…”

This paper proposes a new theory explaining aerodynamic phenomena of airfoils. The theory is based on the application of Newton’s classical mechanics rather than differential equations of fluid dynamics. The approach in developing the equations contains both geometrical and fluid dynamics perspectives of motion of body in a fluid. Based on the theory, it is shown that new airfoil designs could be generated through the application of “contraction” and subsequent “expansion” in the geometry for lift generation. The effect of thickness of airfoil is important in the context of lift and drag and further investigation on its effect on airfoil aerodynamics is conducted. The obtained results are reported and discussed.
