Total enthalpy (h0​) is a thermodynamic property that represents the total energy content of a fluid per unit mass, taking into account both its internal energy and the energy associated with its velocity. It is a concept commonly used in fluid dynamics, aerodynamics, and thermodynamics to describe the energy state of a flowing fluid.  h0​ […]

Specific enthalpy represents the total energy content per unit mass of a substance, taking into account both its internal energy and the energy associated with the work done by or on the substance. It is particularly useful in thermodynamics to analyze energy changes during processes, especially those occurring at constant pressure where the change in

The specific gas constant (R) has different values depending on the units used for pressure, volume, and temperature. The value of R is commonly expressed in different units to match the units of other quantities in various equations. It plays a crucial role in thermodynamics and fluid dynamics, providing a bridge between macroscopic properties like

The maximum lift-to-drag ratio (L/D) refers to the highest achievable efficiency of an aircraft or other flying object in generating lift relative to the amount of drag it produces. It represents the optimal configuration or operating point at which the object generates the most lift for the least amount of drag. The concept of maximum

Parasite drag coefficient (CD,e) is a dimensionless aerodynamic parameter that quantifies the contribution of parasite drag to the total aerodynamic drag experienced by an object moving through a fluid, such as air. Parasite drag refers to the drag force that arises from factors other than lift production, and it includes various forms of non-lift-related resistance

The pressure distribution on the surface of a sphere refers to how the pressure of a fluid varies across different points on the sphere’s surface. In fluid dynamics, the pressure distribution is a critical parameter that provides insights into the forces acting on the sphere and the behavior of the fluid flow around it.  Sphere

The maximum tangential velocity at the top and bottom of a sphere in a fluid flow refers to the highest velocity values experienced by the fluid particles at these specific locations on the sphere’s surface. These velocities occur due to the interaction between the approaching flow and the shape of the sphere.  Freestream Velocity (V∞) 

Dynamic viscosity, denoted by the symbol 𝜇 (mu), is a fundamental property of a fluid that describes its resistance to shear deformation or internal flow. It quantifies the frictional forces between adjacent layers of fluid as they move relative to each other. In essence, dynamic viscosity characterizes how “thick” or “sticky” a fluid is and

Tangential velocity of the surface of a sphere refers to the component of velocity that is parallel to the surface of the sphere at a specific point. It describes the rate at which a point on the surface of the sphere is moving in the direction tangent to the surface, without accounting for any motion
