In fluid dynamics, Sauter mean diameter (SMD) is an average measure of particle size. It was originally developed by German scientist Josef Sauter in the late 1920s. [1] [2] It is defined as the diameter of a sphere that has the same volume/surface area ratio as a particle of interest. Several methods have been devised to obtain a good estimate ...
In all methods the size is an indirect measure, obtained by a model that transforms, in abstract way, the real particle shape into a simple and standardized shape, like a sphere (the most usual) or a cuboid (when minimum bounding box is used), where the size parameter (ex. diameter of sphere) makes sense.
Eratosthenes, who calculated the diameter of the Earth around 240 BC. Graph or network diameter – Length of shortest path between two nodes of a graph; Hydraulic diameter – Measure of a channel flow efficiency; Inside diameter* Semidiameter – Term in geometry; half of a shape's diameter; Sauter mean diameter – Average measure of ...
λ: Gas mean free path (cm) D 50: Mass-median-diameter (MMD). The log-normal distribution mass median diameter. The MMD is considered to be the average particle diameter by mass. σ g: Geometric standard deviation. This value is determined mathematically by the equation: σ g = D 84.13 /D 50 = D 50 /D 15.87
Flux F through a surface, dS is the differential vector area element, n is the unit normal to the surface. Left: No flux passes in the surface, the maximum amount flows normal to the surface.
A 24-year-old California man was electrocuted and died while hanging Christmas lights on Thursday, according to officials. Antonio Pascual was hanging Christmas lights the morning of Nov. 21 on a ...
