The wake flow past an axisymmetric body of revolution at a diameter-based Reynolds number $Re=u_{\infty }D/\nu =5000$ is investigated via direct numerical simulation. study focused on identification coherent vortical motions and the dominant frequencies in this flow. Three are identified wake: vortex shedding motion with frequency $St=fD/u_{\infty }=0.27$ , bubble pumping $St=0.02$ very-low-fre...

Extensions to the first and second theorems of Pappus are presented, whereby centroid a surface or solid revolution can be determined using only geometric properties generating plane curve figure arc revolution. The derivations well suited first-year-level courses in mathematics engineering. From didactic perspective, resulting formulas simple apply, especially since required typically availabl...

Hypersonic flows around spatial vehicles during their reentry phase in planetary atmospheres are characterized by intense aerothermal phenomena. The aim of this work is to analyze high temperature flows around an axisymmetric blunt body taking into account chemical and vibrational non-equilibrium for air mixture species. For this purpose, a finite volume methodology is employed to determine the...
