As the Mach number is defined as the ratio of two speeds, it is a dimensionless quantity. If M < 0.2–0.3 and the flow is quasi-steady and isothermal, compressibility effects will be small and simplified incompressible flow equations can be used.[1][2] 【参考译文】本地声速和因此马赫数...
MACH NUMBER and AIRSPEED vs ALTITUDE MACH NUMBER is defined as a speed ratio, referenced to the speed of sound, i.e. MACH NUMBER ' Velocity of Interest Velocity of Sound (at the given atmospheric conditions) [1] Since the temperature and density of air decreases with altitude, so does ...
Mach Number Compute Mach number using velocity and speed of sound expand all in page Libraries: Aerospace Blockset / Flight Parameters Description TheMach Numberblock computes the Mach number. The Mach number is defined as Mach=√V⋅Va,
The dimensionless Mach number is a means to represent the speed of an object through a fluid (or the speed of a fluid over an object) relative to the speed of sound in the fluid. More formally, the Mach number is defined as: M = V / a where: M is the dimensionless Mach number V...
The Mach number (Ma) is a dynamic measure of fluid compressibility, and is defined as the ratio of flow velocity (v) to sound speed (a):(1)Ma=v/a. From: Advances in Colloid and Interface Science, 2007 About this pageSet alert ...
The Mach number (M) is defined as the ratio of the speed of an object (V) to the speed of sound (a) in the same medium: Mach Number (M) = Speed of Object (V) / Speed of Sound (a) For example, if an aircraft is flying at a speed equal to the speed of sound, its Mach ...
The meaning of MACH NUMBER is a number representing the ratio of the speed of a body (such as an aircraft) to the speed of sound in a surrounding medium (such as air). How to use Mach number in a sentence.
Mach number is generally defined as the ratio between the gas speed and the speed of sound. In centrifugal compressor applications two Mach numbers commonly referred to are the peripheral Mach number (Mu) and the inlet relative Mach number (M1rs). The peripheral Mach number (also known as ...
The dynamic performance of a ram air system will vary with mach number and altitude and this tends to follow the aerodynamic characteristics of the missile .像导弹空气动力特性一样，冲压空气式系统的动态特性随马赫数和高度的变化而变化。This fusion phenomena is called the " mach ...
Mach number M is defined as the ratio of the local flow velocity V to the local speed of sound a. Whence (12.10)M=Va The critical Mach number Mcrit is the free stream Mach number at which the local flow Mach number just reaches unity at some point on the airframe. In general, Mcr...
