The polar angle (θ1) for a doublet is the angle measured in radians from a reference axis (usually the positive x-axis) to a point in the flow field that is affected by the doublet.  sin 𝜃1 is the polar angle for doublet one. (x1, y1) are the Cartesian coordinates of the point the position of […]

The stream function (Ψ) is a mathematical concept used in fluid dynamics to describe the flow patterns of a two-dimensional, incompressible fluid. It helps visualize and analyze fluid motion by representing the streamlines, which are curves that are always tangent to the velocity vector of the fluid at a given point.   Strength of the Doublet

Induced velocity at a specific point P refers to the change in velocity that is caused by the presence of some external influence, such as a moving object or a flow pattern, at that particular point. In fluid dynamics, induced velocity is commonly associated with the influence of vortices, sources, or other flow elements on

The Reynolds number (Re) based on a characteristic length x1 is a dimensionless quantity used to describe the nature of fluid flow past an object, such as a pipe, a cylinder, or an airfoil. It’s a fundamental parameter in fluid dynamics that helps predict whether the flow is laminar or turbulent.  Rex1: Reynolds number based

The length of a line segment, denoted as “l,” refers to the distance between two distinct endpoints along a straight or curved line. In geometry, a line segment is a finite portion of a line with two endpoints. It represents a distinct and measurable portion of the line between two specific points. The concept of

The radial distance, denoted as “r,” is the distance between a given point and a center or axis. In various fields, including mathematics, physics, and engineering, the radial distance is often used to describe the distance of a point from a reference point, origin, or center in a radial or circular pattern.  r: Radial distance

Velocity induced at a given point refers to the change in fluid velocity that occurs due to the presence of an object or disturbance in a fluid flow. This change in velocity is caused by interactions between the fluid and the object, leading to alterations in the flow pattern and direction of the fluid particles.
