The energy ratio (ER) equation you provided, ER = Pt/Pc, relates the total energy output (Pt) to the energy input associated with flow losses in a complete circuit (Pc).  ER is the energy ratio, a dimensionless quantity that represents the ratio of output energy to input energy. It provides a measure of the efficiency or […]

The diameter of a cylinder is the distance between two points on the cylinder’s surface that are farthest from each other and lie on a line passing through the center of the cylinder. In other words, the diameter is a straight line segment that passes through the center of the circular cross-section of the cylinder

cl is the lift coefficient, a dimensionless quantity that represents the lift force generated by an object (such as a cylinder) in a fluid flow. The lift force is perpendicular to the flow direction and is typically normalized by various parameters, including the dynamic pressure and the object’s characteristics.  cl is the Lift coefficient  Γ

The pressure coefficient (Cp) for a cylinder is a dimensionless quantity used in fluid dynamics to describe the pressure distribution around a circular cylinder exposed to a fluid flow, such as air or water. It provides valuable information about the aerodynamic or hydrodynamic forces acting on the cylinder.  Cp is the coefficient of pressure  Γ

The polar angle (θ), also known as the azimuthal angle, is a fundamental concept used in the context of cylindrical or spherical coordinate systems. It is an angle measured in radians that specifies the angular position of a point relative to a reference direction. When considering the velocity potential (φ) in a polar coordinate system,

A vortex of strength Γ, represents a rotational flow pattern in a fluid where the fluid particles circulate around a central axis. The strength of the vortex quantifies the intensity or magnitude of the circulation around this axis.  Γ vortex strength   r is the radial distance from the center of the vortex. Vθ is the

The velocity potential (φ) is a fundamental concept in fluid dynamics that describes irrotational flow patterns, where the fluid particles move without any rotation (vorticity). In the context of vortex flow, the velocity potential is often not defined because vortex flow, by its nature, involves vorticity and rotational motion. In irrotational flow (which can be

The streamlines of a doublet flow refer to the imaginary curves that depict the paths followed by fluid particles in a flow field created by a doublet. A doublet is a theoretical idealization of fluid flow that consists of a combination of a source (emission of fluid) and a sink (absorption of fluid) placed close

The velocity potential (φ) for a doublet in fluid dynamics is a scalar function used to describe the irrotational flow pattern created by a doublet source-sink combination. A doublet is a hypothetical flow pattern that consists of a source (a point that emits fluid) and a sink (a point that absorbs fluid) of equal strength

The stream function (ψ) is a concept used in fluid dynamics to describe the flow of an incompressible and irrotational fluid in two dimensions. It’s a mathematical function that helps visualize and analyze fluid motion.  𝜓 is the stream function V∞ is the free-stream velocity r is the radial distance from the origin (center) of
