Potential flow over a submerged rectangular obstacle: Consequences for initiation of boulder motion

Abstract: AbstractSteady two-dimensional fluid flow over an obstacle is solved using complex variable methods. We consider the cases of rectangular obstacles, such as large boulders, submerged in a potential flow. These may arise in geophysics, marine and civil engineering. Our models are applicable to initiation of motion that may result in subsequent transport. The local flow depends on the obstacle shape, slowing down in confining corners and speeding up in expanding corners. The flow… Show more

“…Reference [50] pointed out that, apart from flaws in the formulas, the estimation of both C L and C D is critical; therefore, instead of applying values excerpted from the literature, the estimation should be accomplished with strict reference to the local physical conditions. As an example, higher values than the one (0.178) usually used for C L were obtained by both field and modeling investigations [51,52]. Such a finding reduces the minimum energy wave required to initiate the boulder displacement (see the equations in Section 5).…”

“…King and Bloor [31] investigated free-surface flow produced by polygonal obstacles, and even devised a numerical conformal-mapping technique based on a continuous Schwarz–Christoffel mapping [32]. More recent flows over rectangular obstacles have been presented by Herterich and Dias [25].…”
