High-reynolds-number wake of a slender body
WebThe Reynolds number normal to the body may be written in terms of the Mach number normal to the body as follows: (7.109)Re=Vdν=(aν)Md Using Eqns (2.16) and (2.21)Equation 2.16Equation 2.21, we may approximate the unit Reynolds number, i.e., the Reynolds number per unit diameter, as follows: (7.110)Red≈2.56×107exp(−z7.16)M WebThere are some particularities that make the study of high-Reynolds-number slender-body wakes especially challenging. Computationally, it is very costly to simulate turbulent boundary layers over long bodies and also resolve their far wake. The problem is tremendously stiff and the required spatial and temporal resolution is enormous.
