WebApr 5, 2024 · With reference to a fluid injection in a single fracture, the proposed solution is validated by comparing it with an analytical solution inan infinite domain. Apart from the slight difference at later stages of the simulation, presumably due to the effect of the finite domain and boundary conditions, the two solutions match quite well. One issue that must be remembered is that the drag of a wing increases quickly as the flight Mach number approaches transonic conditions, a result of the development of shock waves and wave drag. However, such effects are difficult to generalize because the drag depends critically on the specific wing geometry … See more In general, the drag produced on an airplane will also be a function of the Reynolds number and flight Mach number. Therefore, another generalization of the prior approach is to write that (45) although, again, the … See more The purpose of winglets is to increase the effective aspect ratio of the wing but without significantly increasing the span of the wing. The classic “Whitcomb” winglet moves the tip … See more A combination of calculations (maybe even with CFD), wind tunnel measurements, and flight tests can most likely define the drag … See more

WebMar 6, 2024 · An infinite wing will not have any induced drag. There are no wingtips for the air to leak around. A wing will generate less induced drag the closer it gets to approximating an infinite wing. Hence, long slender wings with a high aspect ratio generate less … WebThe results from two-dimensional theory can be considered to apply to three-dimensional wings of infinite span.
