The normal force coefficient for a flat plate (cn) is a dimensionless quantity that measures the ratio of the normal force acting on the plate to the dynamic pressure of the fluid flow. The normal force is the component of the aerodynamic force that is perpendicular to the plate surface, and the dynamic pressure is […]

The pressure coefficient on the lower surface (Cp,l) is a dimensionless quantity that measures the relative pressure difference between a point on the lower surface of a body and the free-stream pressure in a fluid flow field. The pressure coefficient on the lower surface can be used to calculate the aerodynamic forces and moments acting

The maximum pressure coefficient (Cp,max) is a dimensionless quantity that measures the highest relative pressure difference between a point on the surface of a body and the free-stream pressure in a fluid flow field. The maximum pressure coefficient can be used to calculate the aerodynamic forces and moments acting on a body in various flow

The pressure coefficient for hypersonic flow across a normal shock wave is a dimensionless quantity that measures the relative change in pressure due to the shock wave. The pressure coefficient for hypersonic flow across a normal shock wave depends on the Mach number and the ratio of specific heats of the fluid. Pressure coefficient (Cp)

Pressure difference on the surface is the difference in pressure between two points on a surface that forms the boundary between two fluid regions. The pressure difference can be caused by various factors, such as the curvature of the surface, the surface tension of the interface, the density and viscosity of the fluids, and the

Modified Newton’s sine-squared law is a formula that improves the accuracy of Newton’s sine-square law of air resistance for predicting the aerodynamic forces on a body moving in a fluid. The modified law accounts for the effects of the body shape and the flow separation by introducing a correction factor called the Newtonian pressure coefficient.

The Newtonian theory, often referred to as Newtonian physics or classical mechanics, is a fundamental framework in physics developed by Sir Isaac Newton in the late 17th century. It provides a comprehensive understanding of the behavior of objects in motion and is considered one of the cornerstones of physics.  Pressure coefficient (Cp) Angle between a

Newton’s sine-squared law; it states that the pressure coefficient is proportional to the sine square of the angle between a tangent to the surface and the direction of the freestream. Pressure coefficient (Cp) Angle between a normal to the surface (𝜃) in rad

Normal force per unit area refers to the force exerted perpendicularly on a surface per unit area. In other words, it quantifies the force applied by a fluid, solid, or any other medium onto a surface in a direction that is perpendicular to that surface. Pressure is a fundamental concept in physics and engineering and
