Web23 hours ago · The company recorded record free cash flow of $6 billion and an all-time high production increase to an average of 316,000 BPD. They increased the fixed dividend by 11%. WebAway from the half-cylinder the flow is irrotational, ∇ → × u → = 0 →, allowing a potential function to be defined: u = ∂ ϕ ∂ x, w = ∂ ϕ ∂ z. The incompressibility condition reduces to: ∇ 2 ϕ = 0. This is Laplace’s equation. Noting the axial symmetry, the math may be simplified by converting to polar coordinates.

In mathematics, potential flow around a circular cylinder is a classical solution for the flow of an inviscid, incompressible fluid around a cylinder that is transverse to the flow. Far from the cylinder, the flow is unidirectional and uniform. The flow has no vorticity and thus the velocity field is irrotational and can be … See more A cylinder (or disk) of radius R is placed in a two-dimensional, incompressible, inviscid flow. The goal is to find the steady velocity vector V and pressure p in a plane, subject to the condition that far from the cylinder the velocity … See more The symmetry of this ideal solution has a stagnation point on the rear side of the cylinder, as well as on the front side. The pressure distribution over the front and rear sides are identical, leading to the peculiar property of having zero drag on the cylinder, a property … See more Regular perturbation analysis for a flow around a cylinder with slight perturbation in the configurations can be found in Milton Van Dyke (1975). In the following, ε will represent a small … See more Laplace's equation is linear, and is one of the most elementary partial differential equations. This simple equation yields the entire solution for both V and p because of the constraint of irrotationality and incompressibility.
