The average slope of a characteristic line between two points, such as points twelve and thirteen in fluid dynamics, refers to the average rate of change of a certain property or variable along the path defined by the characteristic line as you move from point twelve to point thirteen. This property or variable can vary […]

In fluid dynamics and aerodynamics, a characteristic line is a curve that represents the path along which disturbances in a fluid flow propagate. The average slope of a characteristic line between two points, such as points nine and twelve, typically refers to the average rate of change of a certain property or variable along this

The slope of a right-running Mach wave characteristic between points four and five refers to the rate of change of certain properties of a gas as it passes through a Mach wave that is propagating to the right. In aerodynamics and gas dynamics, Mach waves are shock waves or expansion waves that travel through a

The local total enthalpy at a specific point within a fluid flow, denoted as “h0,2,” is a thermodynamic property that describes the total energy per unit mass of a fluid at that particular location. Similar to the concept of local total enthalpy at point one (h0,1), it takes into account both the internal energy of

The local total enthalpy at a specific point within a fluid flow, denoted as “h0,1,” is a thermodynamic property that describes the total energy per unit mass of a fluid at that point. It takes into account both the internal energy of the fluid and the kinetic energy associated with its motion at that specific

For a calorically perfect gas, the total enthalpy is a thermodynamic property that represents the combination of internal energy, kinetic energy, and potential energy per unit mass of the gas. It is used to describe the energy content of a calorically perfect gas and is especially relevant in fluid dynamics and thermodynamics.  Total enthalpy (h0)

The total enthalpy at any point in a fluid flow, denoted as “h0,” is a thermodynamic property that represents the combination of internal energy, kinetic energy, and potential energy per unit mass of a fluid element. It is used in fluid dynamics and aerodynamics to analyze and understand the behavior of flowing fluids, such as

The mean molecular kinetic energy is an average value that accounts for the fact that there is a distribution of molecular speeds within a gas due to the Maxwell-Boltzmann distribution. It is calculated as the average kinetic energy of all the molecules in the gas.  Mean molecular kinetic energy (KE) in J Boltzmann constant (K)

Dynamic pressure, often denoted as “q,” is a term used in fluid dynamics and aerodynamics to describe the pressure exerted by a fluid (such as air or a gas) in motion. It represents the kinetic energy per unit volume of the fluid due to its motion and is a fundamental concept in the study of

The lift-to-drag ratio, often denoted as L/D, is a fundamental parameter in aerodynamics that quantifies the efficiency of an airfoil, wing, or aircraft in generating lift (the upward force) compared to the amount of drag (the resistive force) it produces. It is a critical metric used to assess the performance and efficiency of an aircraft
